The Touhou Project (Japanese: 東方Project, Hepburn: Tōhō Purojekuto), also known simply as Touhou (東方, literally "Eastern direction"), is a bullet hell shoot 'em up video game series created by one-man independent Japanese doujin soft developer Team Shanghai Alice. Since 1995, the team's member, Jun'ya "ZUN" Ōta, has independently developed programming, graphics, writing, and music for the series, self-publishing 18 mainline titles and five spin-offs as of May 2021[update]. ZUN has also produced related print works and music albums, and collaborated with developer Twilight Frontier on seven official Touhou spin-offs, most being fighting games.
The Touhou Project is set in Gensokyo,[a] a land sealed from the outside world and primarily inhabited by humans and yōkai, legendary creatures from Japanese folklore that are personified in Touhou as bishōjo in an anthropomorphic moe style. Reimu Hakurei, the miko of the Hakurei Shrine and the main character of the series, is often tasked with resolving supernatural "incidents" caused in and around Gensokyo.
The first five titles were developed for the Japanese NEC PC-9800 computer series, with the first, Highly Responsive to Prayers, released in August 1997; the series' signature danmaku (弾幕, lit. 'bullet curtain') mechanics were introduced in the second game, Story of Eastern Wonderland (also 1997). The release of Embodiment of Scarlet Devil in August 2002 marked a shift to Microsoft Windows. Numerous sequels followed, including several spin-offs departing from the traditional bullet hell format.
Touhou Project has become particularly notable as a prominent source of Japanese dōjin content, with the series spawning a vast body of fan-made works such as artwork, music, print works, video games, and Internet memes. Because of this, it has gained somewhat of a cult following outside of Japan. The popularity of the series and its derivative works has been attributed in part to the few restrictions placed by ZUN on the use of his content. Unofficial works are frequently sold at fan conventions, including Comiket, where the franchise has frequently held the record for circle participation, and the official convention Reitaisai, where trial versions of the official games are typically distributed prior to release.

Jun'ya Ōta, who was then a mathematics student at Tokyo Denki University working under the name "ZUN Soft", developed the first five Touhou titles for NEC PC-9800 personal computers, utilizing the platform's 16-bit color graphics and 6-channel FM synthesis audio. The titles were published by Amusement Makers, a student game development club that Ōta was a member of.
- Highly Responsive to Prayers (東方靈異伝, Tōhō Reiiden, lit. "Wondrous Tale")
- The 1st game in the series, was released on August 15, 1997, at Comiket 52. ZUN began development in 1995 and first showcased the game in November 1996 at the 20th Hatoyama Matsuri, the annual fair held at the Hatoyama campus of Tokyo Denki University. It features the first appearance of series protagonist Reimu Hakurei, the miko of Hakurei Shrine (博麗神社 Hakurei Jinja). After the destruction of the shrine, she charges through a gateway to another world, intent on locating and punishing those responsible. It features gameplay similar to Arkanoid and differs from the vertically-scrolling format of later titles. Players direct a Yin-Yang Orb (陰陽玉 Onmyō-gyoku) by side-kicking, swinging Reimu's purification rod (御幣 gohei), and firing amulets (御札 ofuda), with the goal of using it to overturn all the cards in a level. If the player runs out of time, bullets rain down from the top of the screen until the player either completes the level or dies. There are 20 stages, with every fifth stage being a battle where the player must use the orb to deal damage to a boss. After completing Stage 5, the player is given a choice between two routes, Makai (魔界, lit. "Demon World") and Hell (地獄 jigoku), with each featuring distinct stages, bosses, and endings. It introduces the last-resort "Bomb" system, present in some form in all subsequent titles, as well as the four levels of difficulty that would become hallmarks of the series: Easy, Normal, Hard, and Lunatic. According to ZUN, 30 copies of the game were sold.
- Story of Eastern Wonderland (東方封魔録, Tōhō Fūmaroku, lit. "Demon-Sealing Record")
- The 2nd game in the series was released alongside Highly Responsive to Prayers at Comiket 52. Reimu Hakurei returns from a training session in the mountains only to find the Hakurei Shrine overrun by ghosts and yōkai. Excited at the opportunity to test her abilities, she takes off with her Yin-Yang Orbs on the back of her turtle Genjii to seek out the source of the invasion. It is the first vertically-scrolling danmaku (弾幕 "barrage", lit. "bullet curtain") title and also marks the first appearance of Marisa Kirisame, the second major player character in the series, who appears as the Stage 4 boss. ZUN has cited shoot 'em up arcade game Darius Gaiden as an influence for the gameplay, which consists of firing bullets at bosses that appear from the top of the screen while simultaneously dodging their attacks. It is the only game in the series with five stages (excluding the extra stage). The game introduces many features that would later become standard, including weapon selection, hitboxes that are smaller than the player character, power-ups, mid-bosses, and an unlockable Extra Stage. 50 copies of the game were sold.
- Phantasmagoria of Dim. Dream (東方夢時空, Tōhō Yumejikū, lit. "Dream Space-Time")
- The 3rd game in the series was released on December 29, 1997, at Comiket 53. While enjoying a quiet morning walk, Reimu Hakurei stumbles across mysterious ruins that have suddenly appeared a short distance from the Hakurei Shrine's gateway. She joins in a violent competition with several others who want to explore them, as it is said that the one who reaches the heart of the ruins first will win a prize. In Match Play Mode, it is a versus-type scrolling shooter similar to Twinkle Star Sprites, in which two players engage in danmaku battles in split-screen. In Story Mode, the player faces off against nine increasingly skilled AI opponents. The combat makes use of a "Spell Gauge", with characters unleashing attacks of varying strength based on their charged level of magical power. Approximately 100 to 150 copies of the game were sold.
- Lotus Land Story (東方幻想郷, Tōhō Gensōkyō, lit. "Fantasy Land")
- The 4th game in the series was released on August 14, 1998, at Comiket 54. The peace in Gensokyo (first used in this entry's title) is broken when a tremendous energy surges from beneath a mountain lake, causing yōkai to swarm the Hakurei Shrine. Reimu Hakurei and Marisa Kirisame travel to seek out and eliminate the source of the disturbance, battling yōkai along the way. It features six stages, with the game ending after Stage 5 if the player selects Easy difficulty or uses a "continue". A notable new feature is a "graze" counter for near-misses. According to ZUN, 200 to 300 copies of the game were sold.
- Mystic Square (東方怪綺談, Tōhō Kaikidan, lit. "Bizarre Romantic Story")
- The 5th and final Touhou game for the PC-98 was released on December 30, 1998 at Comiket 55. When demons begin emerging from a cave high in the mountains of Gensokyo, Reimu Hakurei and others must travel to the depths of Makai to confront the one behind the incident. Mima and Yuuka, the final bosses of Story of Eastern Wonderland and Lotus Land Story respectively, return as playable characters along with Marisa Kirisame. The game contains six stages and includes a "Dream Gauge" system, which rewards the player for collecting items by clearing all enemy bullets when it is filled to maximum.
After the release of Mystic Square, ZUN graduated from university and the series became inactive for four years. During this time, he worked at Taito Corporation as a game developer and also composed music for various games created by members of Amusement Makers. He left the group in 2001 to focus on game development for Microsoft Windows, forming the one-man dōjin circle Team Shanghai Alice and self-publishing all subsequent titles. According to ZUN, the Windows games represent a "clean slate" for the series canon, albeit with many carry-overs and references from the PC-98 era. Games numbered with decimals are spin-offs from the main series that vary in genre.
- Embodiment of Scarlet Devil (東方紅魔郷, Tōhō Kōmakyō, lit. "Scarlet Devil Land")
- The 6th game in the series and the first on Windows was released on August 11, 2002, at Comiket 62. It marked a dramatic graphical improvement from the PC-98 games, and the game's music and sounds used synthesized PCM and MIDI instead of FM synthesis. It introduces the "Spell Card" system, in which bosses fire danmaku patterns in a specific sequence as their health is depleted, with a health bar and unique name for each attack appearing on screen as it is used. For comparison, in the PC-98 games, boss characters would have a select few danmaku patterns that they would switch between at random.
- A peaceful summer in Gensokyo is interrupted when an ominous scarlet mist blocks out the sun. As either the shrine maiden Reimu Hakurei or the magician Marisa Kirisame, the player must infiltrate the Scarlet Devil Mansion (紅魔館 Koumakan) and confront the mysterious Scarlet Devil that lives within. The game features the debut of Sakuya Izayoi, who would become a playable character in several sequels.
- Several features from the PC-98 era were re-introduced in Embodiment of the Scarlet Devil, which set a standard for the later Windows titles. At the start of a game, the player must choose an attack style, which affects their character's weapon type and Spell Card bomb. A limited number of these "bombs" are provided as a method of escaping from difficult situations by dealing heavy damage to enemies, cancelling enemy bullets, and collecting all items on the screen. A notable feature added in this title and present in future main titles is Focused Fire mode, which allows the player to slow their movement and focus their shots when activated. The game features six increasingly difficult stages, with the boss of each stage being preceded by a less powerful "midboss". Playing on Easy difficulty causes the game to prematurely end after Stage 5, and completing the game after using a "continue" results in a bad ending. Once a good ending has been achieved on Normal or higher difficulty, the player unlocks a bonus "Extra Stage", which features the game's final boss battle.
- Perfect Cherry Blossom (東方妖々夢, Tōhō Yōyōmu, lit. "Ghostly Dream")
- The 7th game in the series, released on August 17, 2003, at Comiket 64. As the month turns to May, it is clear that winter in Gensokyo has lasted far longer than normal. As Reimu, Marisa, or Sakuya, the player must embark on a trip to the Netherworld (冥界 Meikai, lit. "Realm of the Dead") to find those responsible for stopping the coming of spring. With the addition of Sakuya, Perfect Cherry Blossom continues the series tradition of former bosses reappearing as playable characters. It also features a "Cherry Gauge", which is filled by grazing, shooting enemies, and completing Spell Cards without using bombs, which when full, activates a "Supernatural Border", giving the player a temporary shield. Alice Margatroid from Mystic Square makes her Windows debut in this game. As well as featuring an extra stage, the game also has an unlockable phantasm stage that can be accessed after the player clears the extra stage and has captured a certain amount of spell cards.
- Immaterial and Missing Power (東方萃夢想, Tōhō Suimusō, lit. "Gathering Reverie")
- The 7.5th game in the series and the first versus fighting game released on December 30, 2004, at Comiket 67. It is a 2D fighting game with danmaku influences, as reflected by its heavy emphasis on Spell Card projectile attacks. As with all the official fighting games, it was primarily developed by Twilight Frontier, with ZUN providing scenarios, Spell Card designs, and several music tracks. Between the events of Perfect Cherry Blossom and Imperishable Night, a strange mist descends on Gensokyo as Reimu Hakurei and other residents find themselves inexplicably holding a feast every three days. Initially playable characters include Reimu, Marisa, Sakuya, Alice, Youmu Konpaku from Perfect Cherry Blossom, and Patchouli Knowledge from Embodiment of Scarlet Devil.

- Imperishable Night (東方永夜抄, Tōhō Eiyashō, lit. "Eternal Night Vignette")
- The 8th game in the series released on August 15, 2004, at Comiket 66. It is the eve of Gensokyo's yearly Harvest Moon Festival (月見 Tsukimi) when it is discovered that the moon has been replaced with a fake. Two-person teams of humans and yōkai set out into the Bamboo Forest of the Lost (迷いの竹林 Mayoi no Chikurin) to confront the culprits and restore the moon before the night is over. The four playable teams are the Illusionary Barrier Team (Reimu Hakurei and Yukari Yakumo), the Aria of Forbidden Magic Team (Marisa Kirisame and Alice Margatroid), the Visionary Scarlet Devil Team (Sakuya Izayoi and Remilia Scarlet), and the Netherworld Dwellers' Team (Youmu Konpaku and Yuyuko Saigyouji), with the player swapping between characters on a team by activating Focused Fire mode. It adds powerful "Last Spell" Cards for players and enemies, as well as "Time Orb" items that affect the story by changing the speed at which the night passes.
- Phantasmagoria of Flower View (東方花映塚, Tōhō Kaeizuka, lit. "Flower Reflecting Mound")
- The 9th game in the series released on August 15, 2005, at Comiket 68. The game is a split-screen versus-type shooter similar to Phantasmagoria of Dim. Dream.

"(Burial) Mound of the Nameless") and reveal the truth behind the abnormal spring.

Playing as tengu reporter Aya Shameimaru, the player is tasked with photographing bosses and their danmaku in 10 increasingly difficult stages. The game is unique in that the player has no standard shot or bombs; rather, the camera is the main method of offense and defense, as it clears bullets from the screen when used. Scoring is based on the contents of each photo, including the amount and type of bullets included. The game features bosses from Embodiment of Scarlet Devil to Phantasmagoria of Flower View.
- Mountain of Faith (東方風神録, Tōhō Fūjinroku, lit. "Wind God Chronicles")
- The 10th game in the series released on August 17, 2007 at Comiket 72. This entry marks a "soft reboot" for the series, with a total overhaul of the game engine that resulted in substantial design and pacing changes. The bomb counter has been removed and replaced by the "Options" system, which adds up to four "satellites" that hover near the player and fire bullets. They can be obtained by collecting power items, and have additional effects based on selected weapon type. The "Faith" system is also used, where players can collect green "Faith" items to increase the value of point items. the game is also one of three games in the series that allows the player to have unlimited continues, but using one results in the player having to restart the current stage.
- One autumn, Reimu receives a message demanding the closure of Hakurei Shrine and threatening its destruction at the hands of the god of Yōkai Mountain.

In the shooting games, the player's bullet power increases on a linear scale as the player collects power-ups dropped by enemies, and eventually maxes out. The player can also collect "point" icons to earn extra lives; the amount needed grows exponentially as the player's score rises. The player can enter "focus mode" by holding the shift key by default, which slows down the player's movement, makes their hitbox visible (from Perfect Cherry Blossom onwards), and generally focuses the player's attack to make it more powerful. The graze counter, missing from Mountain of Faith and Story of Eastern Wonderland, tracks how many bullets entered the character sprite but avoided the hitbox, rewarding the player with a score bonus for taking risks.
The player can use a "bomb" or "spell card", similar to the "bomb" in many other shooting games. Although the player has a limited number at any given time, losing a life replenishes the current number of bombs up to a certain amount. With some exceptions, use of a bomb will make the user temporarily invulnerable, clear many of the bullets, and cause heavy damage to any enemies on screen. The overall effect the bomb has varies by character and by game. The player can use one during a short period after being hit by a bullet (called a "deathbomb") to avoid loss of a life. The amount of time the player has available to deathbomb is usually around 0.3 seconds (8 frames). Bosses have attack phases, which are also referred to as spell cards, but with bosses the term applies to a prolonged pattern of movements and shots that last until the player depletes the boss' health by a certain amount or the time runs out.
Each individual game of the main series from Perfect Cherry Blossom to Wily Beast and Weakest Creature has additional items that affect some aspect of gameplay, such as scoring or gaining extra lives/bombs. For example, Perfect Cherry Blossom has "cherry points", which are used mostly in scoring, but can grant temporary invulnerability (known as the "supernatural border"); Imperishable Night has "time points", which are essential for advancing to later stages, and also determine if the player gets to challenge a boss's 'final spell' on normal or higher difficulties; Mountain of Faith has "faith" points, which boost the score the player receives upon gathering point items and bonuses for clearing spell cards without dying or using a spell card.
Each main Touhou game has four difficulty levels—easy, normal, hard, and lunatic—with each one being harder than the previous. Regardless of difficulty choice, there are six stages in each game that become progressively difficult. The only exceptions to this are Story of Eastern Wonderland and Embodiment of Scarlet Devil on easy difficulty, both of which only have five stages.
In addition to the four main difficulties, there is an extra stage, unlocked after completing the game without using any continues. The extra stage is considerably more difficult than the regular game, and contains an especially long boss fight (usually with ten spell cards). Bosses in extra stages are usually immune to bombs. The only games that allow players to reach the extra stage by completing the easy difficulty are Story of Eastern Wonderland, Mystic Square, Perfect Cherry Blossom, Imperishable Night, Fairy Wars, Double Dealing Character, Legacy of Lunatic Kingdom, Hidden Star in Four Seasons, and Wily Beast and Weakest Creature. In Perfect Cherry Blossom, there is a phantasm extra stage where the difficulty is increased even further. The phantasm stage is accessed by beating the extra stage and capturing at least 60 spells with any of the characters and weapon types combined.
- 1CC (one credit clear)
- Completing a game without running out of lives. A 1CC is required to unlock the Extra Stage, and get the good ending.
- A weapon given to the player that will clear the screen of enemy bullets, deal large amounts of damage, and give temporary invulnerability. The bomb's power is offset by its lack of availability, with most characters typically starting with two. In Mountain of Faith and Subterranean Animism, bombs are not given their own counter, but instead consume some of the player's shot power. From Imperishable Night onward, they are referred to as Spell Cards.
- Surviving an enemy Spell Card without dying, bombing, or running out of time.
- Using a bomb shortly after being hit (normally within 8 frames), which prevents the player from losing a life.
- Extra Stage
- The final stage in each Touhou game, unlocked after a 1CC of the regular game. The Extra Stage is shorter than a stage in the regular game, but also much harder.
- Focus Mode
- An ability which can be activated at any time, which will slow the player down, making them easier to control. Focus Mode was introduced in Lotus Land Story, and has appeared in every shoot 'em up Touhou game since. Since Perfect Cherry Blossom, activating Focus will show the player's hitbox, and tighten their cone of fire.
- Having enemy bullets reach the edge of the player's hitbox.
- The part of the player sprite that determines if they have been hit by an enemy bullet.
- Any of several power-ups that will appear for the player to collect. These can give the player extra bombs, lives, shot power, or points.
- Point of Collection
- An area towards the top of screen, that will collect all onscreen items when it is approached. Only present in the Windows games, it can only be activated at full shot power in Embodiment of Scarlet Devil and Perfect Cherry Blossom, and in Imperishable Night, Marisa is the only character that can activate it without full shot power.
- The player's main method of attack, that differs depending on the chosen character, and, in every game except Lotus Land Story, each character will have at least two shot types to choose from.
- Slow Mode
- An optional feature in Lotus Land Story, Mystic Square, Perfect Cherry Blossom and Imperishable Night that reduces the frame rate when a large number of bullets are onscreen, making them easier to avoid.
- Spell Card
- The name given to specific attacks used by bosses. Also used in reference to bombs.
The plots of the Touhou Project revolve around the strange phenomena that occur in the fictional realm of Gensokyo (幻想郷, Gensōkyō, literally Fantasy Village or Fantasy Land), which ZUN designed with a human village in some remote mountain recesses in Japan. Originally, it was simply called "a remote separated land of a human village in an eastern country." Long before Touhou Project's story begins, many non-humans like yōkai lived with some humans in the area. After a few humans disappeared into Gensokyo, many humans became afraid of approaching this area, while others settled there to exterminate yōkai. However, as time went on, humans developed civilization and multiplied in number, and thus yōkai worried about how the balance between humans and yōkai would be affected. 500 years before Embodiment of Scarlet Devil (EoSD), the yōkai sage Yukari Yakumo developed the "boundary of phantasm and substance," which was favored by the yōkai and protected the balance. This was called the "Yōkai Expansion Project" and made Gensokyo a phantasmal world that automatically called out to the weakened yōkai of the outside world. Other things that disappear from the outside world, like extinct animals, lost tools, and architecture, appear in Gensokyo. Since Gensokyo was a plot of land in Japan that is separated by a barrier, it is Japan that is immediately outside of this barrier.
As a result of the seal, Gensokyo became inaccessible from the outside world, and similarly, those in Gensokyo were unable to leave. Gensokyo's existence could not be confirmed from the outside world, nor could the outside world be confirmed within Gensokyo. As a result, the isolated community developed its own civilization, separate from the outside world. Although separated by a barrier, it is a bordering world to its outside, as opposed to being in a parallel universe. There are no seas in Gensokyo, since it is landlocked. In Gensokyo, there are few humans, and various kinds of yōkai. Some species include magicians, beasts, therianthropes, vampires, bōrei, tengu, mermaids, kappa, and yōkai (a kind of miscellaneous group). There are others species that could be yōkai depending on definition, like fairies, spirits, yūrei, onryō, poltergeists, hermits, oni, and gods which are all portrayed in human female form.
In present Gensokyo, presented in all Touhou Project games since EoSD, magical and spiritual qualities prevail compared to the outside world where unscientific phenomena were dismissed as "superstition" around the time of the Meiji era. The only known gateway from the outside world into Gensokyo is the Hakurei Shrine on the border of Gensokyo. The spell card rules were also established to keep up the relationship between humans and yōkai in a mock style, which was necessary for the preservation of the balance of Gensokyo. The "Great Hakurei Barrier," managed by past Hakurei miko, was constructed several decades before EoSD, which is described as a "barrier of common sense," and is thus a strong logical barrier that not even yōkai can pass through. The yōkai opposed its construction at first before understanding its usefulness.
In Gensokyo, events called "incidents" occur once in a while. An incident is an event that affects all of Gensokyo and is of unknown cause at the time it occurs. Touhou Project mainly focuses on incidents that affects the entirety of Gensokyo in its stories, but there are also works like Mountain of Faith that are centered on lesser-scale events.
Frequently, incidents are due to a yōkai's whim or curiosity, and usually Reimu Hakurei would go to investigate it and find and chastise the perpetrator. While Reimu is usually the one to resolve incidents, there are cases where Marisa Kirisame and other characters would resolve them. When a major incident occurs, the spirits and fairies are affected by the incident and experience an increase in power for the duration incident.
With its focus on bishōjo characters, the Touhou series possesses a large cast compared to other shooting games. While they are not developed nearly to the standards of a story-based game, many players love them. One example is Hong Meiling, affectionately called Chūgoku (China), the stage 3 boss of Embodiment of Scarlet Devil, who won a popularity contest in Japan out of all Touhou characters. Among the vast array of characters, only six named characters are male. One (Genjii) is a turtle, one is a cat (Sokrates), two (Youki Konpaku and Myouren Hijiri) are only mentioned in passing, one (Rinnosuke Morichika) who is a merchant is only featured in the serialized novel, and the last (Unzan) is a cloud-like entity. There is also one before all these (Shingyoku), but this character has three forms of different genders, so this character may not exactly be male.
Though each game features a collection of different characters, the main protagonist of the series is always Reimu Hakurei, joined by Marisa Kirisame after the second game. Exceptions to this include Shoot the Bullet and Double Spoiler (Aya Shameimaru is playable on both, and Hatate Himekaidou can become playable in Double Spoiler), Fairy Wars (which has Cirno as the sole playable character), Impossible Spell Card and Gold Rush (where only Seija Kijin is playable), and Violet Detector (where only Sumireko Usami is playable).
The Touhou Project is a one-man project by Jun'ya Ōta (usually under the pseudonym ZUN), who does all the graphics, music, and programming alone for the bullet hell games, with the exceptions of the portrait art in Fairy Wars, which was done by Makoto Hirasaka. The fighting games, Immaterial and Missing Power, Scarlet Weather Rhapsody, Touhou Hisōtensoku, Hopeless Masquerade, Urban Legend in Limbo, and Antinomy of Common Flowers, were dual efforts with Twilight Frontier, in which ZUN wrote the music and story, and Twilight Frontier created the art and gameplay.
ZUN's first interest in developing video games came during his high school years. While most shoot 'em up games utilise a military or science fiction theme, ZUN wanted a game with a miko main character, and a Shinto aesthetic. ZUN was part of his school's orchestra club, and originally wanted to create music for video games. He went to college, hoping to compose music for fighting games, since they were popular at the time due to Street Fighter II. As he did not know anybody else who was making games that he could put his music in, he made his own games for this purpose, which led to the first Touhou game, Highly Responsive to Prayers, being released in 1996. The first game was originally intended as a practice in programming. Touhou only became a shooting game series from the second game onwards, because the popularity of shooting games had revived due to RayForce and ZUN had long been a fan of such games. ZUN remarked how the general theme and direction of Touhou only started coming together in the sixth game, Embodiment of Scarlet Devil.
Reception and fanworks
Many derivative works based on Touhou have been created since the release of Embodiment of Scarlet Devil, including dōjinshi, dōjin music (many of the songs had been made remixing the original games' music), dōjin anime, and dōjin games (even though the Touhou games themselves are dōjin games). The vast scope of Touhou derivatives prompted commentary, noting that Touhou Project became an unmissable aspect of Japanese consumer generated media. These dōjin activities are mostly responsible for adding original attributes to characters that ZUN may not have intended. ZUN, for the most part, had acknowledged, appreciated, and even encouraged these derivative works by imposing very few restrictions on the use of his works. The major restrictions are on unauthorized commercial distribution (as opposed to dōjin) and the spoiling of endings; proper attribution to Team Shanghai Alice is a requirement. ZUN stated himself that he did not want the Touhou Project game series to be officially commercialized.
The first publication of Touhou derivative doujinshi occurred during December 2003, following the release of Perfect Cherry Blossom; seven circles sold Touhou derivative works at Comiket 65 in December 2003. At Comiket 74 in August 2008, a total of 885 circles had Touhou derivative works on display or for sale, out of a total of 35,000 circles participating at Comiket. At Comiket 77 (December 2009), 2,372 circles were dedicated to Touhou, breaking the previous record held by The Prince of Tennis at Comiket 66 (August 2004), which had 2,130 circles. At Comiket 85 (December 2013), Touhou was still in the lead, with 2,272 participating circles selling Touhou derivatives, compared to Kuroko's Basketball, the second most popular franchise at that year's Comiket, which had 1,462 circles. Throughout the mid 2010s, Touhou's popularity at Comiket began to diminish. From 2015-2017, Kantai Collection was consistently the most popular series at Comiket. By 2019, Touhou was the fourth most popular series at Comiket, with less than half the circles at Comiket than the Fate series.
The dōjin games based on Touhou include adaptations of other game series' mechanics with Touhou characters, such as Kōmajō Densetsu: Scarlet Symphony (a parody of the Castlevania games with the title being a play on the Japanese title of the series, Akumajō Dracula), Age of Ethanols (based on the Age of Empires series), and Touhou Puppet Dance Performance (based on the Pokémon games).
At Tokyo Game Show 2014, ZUN announced a collaborative project with PlayStation bringing unofficial, fan-made Touhou Project dōjin games to the PlayStation 4 (PS4) and PlayStation Vita platforms. Yuyuko Saigyouji and Reimu Hakurei also made cameo character appearances in Square Enix's game Lord of Vermilion Re:2.
The music of Touhou has been a particular source of interest, and many arrangement CDs are sold at Comiket and other Japanese conventions. Among the most popular derivatives are the series of Flash music videos created by the dōjin music circle IOSYS, which are often shared on otaku internet forums and Nico Nico Douga. One such song, Marisa Stole the Precious Thing, was parodied in derivative anime music videos. Marisa Stole the Precious Thing, alongside Cirno's Perfect Math Class, Night of Nights, and Bad Apple were included in the dōjin game Touhou Spell Bubble. Toby Fox, the creator of Undertale, cited Touhou as one of his musical influences.
Several fanmade anime have been made for Touhou. Albeit created by amateur studios, the projects have sometimes included appearance by professional voice actors, such as Rie Tanaka. Dōjin anime of note include Fantasy Kaleidoscope ~ The Memories of Phantasm (幻想万華鏡) by the circle Manpuku Jinja in 2011, A Summer Day's Dream (夢想夏郷) by the dōjin circle Maikaze, and Hifuu Club Activity Record ~ The Sealed Esoteric History (秘封活动记录) by the Chinese dōjin circle Kyoto Fantasy Troupe. A derivative anime from a commercial anime studio came in the form of Anime Tenchou x Touhou Project (アニメ店長 x 東方Project) by Ufotable to celebrate the 10th anniversary of Japanese goods chain Animate as a promotional video for the store combining Touhou with Animate's mascot, Meito Anizawa.
The Touhou Project was nominated for the 11th annual Media Arts Awards held by Japan's Agency for Cultural Affairs, under the Entertainment category, where Touhou Project eventually lost to Nintendo's Wii Sports for the Grand Prize award. The series was inducted into the Guinness World Records in October 2010 as the "most prolific fan-made shooter series".
A major Internet meme based on Touhou is "Yukkuri shite itte ne!!!" (ゆっくりしていってね!!!, often translated as "You should be taking it easy!!!"), which centers around the disembodied, deformed heads of Touhou characters, often referred to as "yukkuris". This meme originated from a disfigured attempt to draw the main characters Reimu and Marisa with Shift JIS art. Yukkuris became so popular that the phrase "Yukkuri shite itte ne!!!" won bronze for 2008's "Net Slang of the Year" in Japan. Yukkuris also appear in Internet advertisements, the anime Natsu no Arashi! and Pani Poni Dash!, and most notably, the front page of 2channel, the largest Internet forum in the world.
The Hakurei Shrine Reitaisai (博麗神社例大祭, Hakurei Jinja Reitaisai, Hakurei Shrine's Regular Grand Festival) is the largest of the many dōjin conventions hosting only Touhou content. Although the coordinator of this convention has nothing to do with Team Shanghai Alice officially, the name "Hakurei Shrine Reitaisai" was given by ZUN himself. It first started in 2004 as a way for Team Shanghai Alice to publicly distribute the trial version for their upcoming games, Imperishable Night and Immaterial and Missing Power. In addition, the 2004 Reitaisai featured a total of 114 participating circles. Since then, many Touhou derivative works are gathered and sold there. Commencing every year in April or May, the convention has been hosted in Ōta, Tokyo, in 2004; Naka-ku, Yokohama, in 2005; Sunshine City, Tokyo, in 2006 and 2007; and the Tokyo Big Sight from 2008 onwards. In 2010 Reitaisai SP, an additional Reitaisai to be held every autumn due to increasing popularity, was started, but it was cancelled after 2011, and later brought back and rebranded as Autumn Reitaisai from 2014 onwards. The 2011 Reitaisai was originally cancelled due to safety concerns after the 2011 Tōhoku earthquake and tsunami, and the release of Ten Desires was also postponed. It was later rescheduled and held on May 8, 2011, with approximately 4,940 participating circles. In addition to events in Japan, there is another Reitaisai held in Taiwan that started in 2015. The 17th Reitaisai in 2020, which was originally going to run on March 22 before being postponed to May 17, was ultimately cancelled due to safety concerns over the COVID-19 pandemic, making it the first Reitaisai to be cancelled.
