1997–2000: Beginning, Michiyo Heike & Morning Musume
In 1997, Japanese rock group Sharam Q, fronted by Tsunku, began auditions for a female vocalist. These auditions aired via the reality show Asayan, and resulted in Michiyo Heike being crowned winner. Tsunku, however, decided to give five of the runners-up, Yuko Nakazawa, Natsumi Abe, Kaori Iida, Asuka Fukuda and Aya Ishiguro, a chance to become a group in their own right. The girls were set the task of selling 50,000 copies of their demo single "Ai no Tane," in just five days. The girls sold the required number of copies in four days, and subsequently became an official group.
Morning Musume's debut single, "Morning Coffee," was released on January 28, 1998 on the One Up Music label and charted at #6 on the Oricon weekly chart. The group's first official appearance was a joint live in August 1998, at Shibuya Public Hall (now Shibuya C.C. Lemon Hall), under the name "Michiyo Heike and Morning Musume," (平家みちよとモーニング娘。) the fan club of the two acts was called "Hello!" The first official "units" were Tanpopo and Petitmoni, created in October 1998. The first "Michiyo Heike & Morning Musume Imotōbun Audition" took place, resulting in the "second generation" of Morning Musume to be added, made up of Sayaka Ichii, Mari Yaguchi and Kei Yasuda.
In January 1999, auditions for Country Musume were held on "Idol o Sagase!" (アイドルをさがせ! Search For an Idol!). In April of that year the girls' official fan club was renamed "Hello! Project." Auditions were once again held on Asayan between April and July, resulting in Taiyō to Ciscomoon and Coconuts Musume, with Country Musume's official formation announced. In July, the first live concert of Hello! Project, "Hello! Project '99 at Yokohama Arena," was held.
2001–2006: Rise to popularity, Berryz Kobo & C-ute
In March 2001, Morning Musume co-founder and leader Yuko Nakazawa announced her graduation from the group. The actual graduation took place in April, and Nakazawa was subsequently named as leader of the entirety of Hello! Project. Nakazawa's was the first graduation in the history of Hello! Project, and garnered considerable media attention as a result, the first time the group had truly caught the attention of the mainstream press.
Between April and June 2002, the first, and to date only, Hello! Project Kids auditions were held. These auditions resulted in the future members of Japanese idol groups Berryz Kobo and C-ute, who would go on to debut in March 2004 and February 2007 respectively, also spawning offshoot auditions such as auditions for Hello! Pro Egg and Hello! Project Kansai. On July 31, 2002, a major reform of all of the groups within Hello! Project began, which was referred to as "Haromageddon" (ハローマゲドン) (a pun on Hello (ハロー, Harō) and Armageddon (ハルマゲドン, "Harumagedon")) and "the 7/31 incident" by fans.
In February 2006, former Morning Musume member and sub-leader of duo W, Ai Kago was caught smoking in public while underage. She was also suspected of dating a much older man. Kago was suspended from her activities and eventually began to attempt a return.
On March 26, 2007, Kago was again caught smoking. Her contract was terminated and she had no graduation ceremony, as had become standard for exiting members.
In June, it was announced that Asami Konno, who had graduated from Hello! Project a year prior to study at university, would be returning. Konno became the first person to have graduated from Hello! Project to return.
2007–2010: Expansion to Taiwan & South Korea, and S/mileage formation
In April 2008, the debut of Hello! Project Kansai group Sina (SI☆NA) was announced. The group never actually debuted, though they occasionally appeared on television shows and radio they have never recorded a song.
In September it was announced that, as a result of the Taiwanese auditions, the group Ice Creamusume (アイスクリー娘。) would be formed, consisting of six members. Duo Francis & Aiko, both still only children, was also announced from the same audition.
On October 19, 2008, Hello! Project announced its entire Elder Club would be graduating on March 31, 2009.
2008 also marked the first time in a decade that Morning Musume had no performed at the annual Kōhaku Uta Gassen event, after ten consecutive appearances. The only Hello! Project member to appear on that year's show was Mai Satoda, marking the first appearance of a member of Country Musume.
On February 1, 2009, at the Yokohama Arena, Hello! Project held its largest concert ever—the Hello! Pro Awards '09: Elder Club Graduation Special (決定！ハロ☆プロアワード’０９ ～エルダークラブ卒業記念スべシャル～ Kettei! Hello Pro Awards '09: Elder Club Sotsugyō Kinen Special)—featuring 21 groups and 72 members. Former Morning Musume member Nozomi Tsuji performed in her first official event in a year and nine months, after marrying actor Taiyō Sugiura in June 2007 and giving birth to her daughter, Noa, that November. During the concert, former Hello! Project leader Yuko Nakazawa passed her leadership position to Morning Musume leader Ai Takahashi. This mass-graduation caused another large surge of fan backlash, resulting in even more fanclub cancellations and merchandise boycotts, and is considered the "third coming of Haromageddon".
Later in 2009, several of the old, dormant units were revived. Tanpopo, Minimoni, Petitmoni, ZYX, Aa! and v-u-den all returned with new line-ups, and High-King returned from hiatus with its original members. These groups became a new concert unit, "Champloo".
In August 2009, Morning Musume released their 40th single, 'Nanchatte Ren'ai'.
2011–2014: Additional Members Added to Morning Musume and S/mileage
In 2011, the most members were added since Hello! Project Kids back in 2002 - Morning Musume's 9th generation: Mizuki Fukumura, Erina Ikuta, Riho Sayashi, and Kanon Suzuki in January, S/mileage's 2nd generation: Kana Nakanishi, Fuyuka Kosuga, Akari Takeuchi, Rina Katsuta, and Meimi Tamura in August, and Morning Musume's 10th generation: Haruna Iikubo, Ayumi Ishida, Masaki Sato, and Haruka Kudo in September.
On January 28, 2011, Dream Morning Musume was formed consisting of previous Morning Musume members such as Yuko Nakazawa, Kaori Iida, Abe Natsumi, Kei Yasuda, Mari Yaguchi, Rika Ishikawa, Hitomi Yoshizawa, Nozomi Tsuji, Makoto Ogawa, Miki Fujimoto, and Koharu Kusumi. Asami Konno was set to debut with the group, but she chose to become a TV announcer. On April 20, 2011, the group released their first album called Dorimusu ①. Their first single was released on February 15, 2012 called Shining Butterfly. The group lasted till their last concert held at the Nippon Budokan on March 10, 2012 which featured former Morning Musume members Aya Ishiguro, Maki Goto, and current Morning Musume members.
On April 6, 2011, Morning Musume released their 45th single called Maji Desu ka Ska!.The single was originally scheduled to be released on March 23, 2011, but it was postponed to April 6 due to the 2011 Touhoku earthquake and tsunami. It is the debut single of Morning Musume's 9th generation members.
On June 15, 2011, Morning Musume releases their 46th single called Only you. Riho Sayashi was the only member out of all the 9th generation members to receive solo lines deeming her as the next ace of Morning Musume.
On August 14, 2011, 5 new sub-members were set to join S/mileage. On August 27, Saki Ogawa graduated from S/mileage and Hello! Project. A few days later on September 9, Fuyuka Kosuga leaves S/mileage. Although Kosuga left the group, she still debuted with the rest of the sub-members and the three remaining S/mileage members on September 28 with Tachiagirl. The sub-members in S/mileage became official 2nd generation members on October 16.
On December 31, 2011, Yuuka Maeda graduates S/mileage.
On January 2, 2012 at the Hello! Project 2012 Winter concert, Morning Musume leader Risa Niigaki announced that she would graduate at the end of Morning Musume's 2012 Spring tour. Niigaki's last single in Morning Musume was in Renai Hunter which was released on April 11, 2012. Niigaki officially graduated Morning Musume and Hello! Project on May 18, 2012 passing on leadership for both Morning Musume and Hello! Project to Sayumi Michishige.
In July 2012, Morning Musume released their 50th single, 'One Two Three / The Matenrō Show'.
2013–2014: Tsunku's Laryngeal Cancer and Juice=Juice
In the last concert of the Winter 2013 Hello! Project concert, a new unit consisting of Hello! Pro Kenshuusei members Miyamoto Karin, Kanazawa Tomoko, Uemura Akari, Otsuka Aina and Takagi Sayuki, and Miyazaki Yuka was announced, although it has been stated that this is not the definitive lineup and members may change before their official debut. It was subsequently announced on February 25 that the new unit would be called Juice=Juice and it would soon release its first indie single. At a Hello Project concert series held on March 2–3, Juice=Juice already premiered the song.
In March 2014, a shocking blog post by Tsunku was posted, saying that he had laryngeal cancer, this was found out after having throat surgery due to its unspecified condition. He announced on his official site that he has been seeking treatment for it. On April 4, 2015, Tsunku revealed that he had his vocal cords removed as part of his cancer treatment. In his memoir, "Dakara, Ikiru", which was published in September 2015 - it was revealed that he stepped down as Hello! Project's General Manager sometime after Morning Musume's New York concert that happened on October 5, 2014. He still remains involved with Morning Musume as its Sound Producer.
On November 26, 2014, Sayumi Michishige graduated and handed her position of Leader of Morning Musume over to fellow member Mizuki Fukumura and announced Erina Ikuta and Haruna Iikubo as sub-leaders. Michishige also handed her position as Hello Project Leader to C-ute's Maimi Yajima. This is the first time in Hello! Project history for the Leader of Hello! Project to not be from the flagship group: Morning Musume.
2015–Present: New Era, Country Girls, Kobushi & Tsubaki Factory, and Major Line-Up Changes
On January 2, 2015, during the Hello! Project 2015 WINTER concert, a new Hello! Project unit consisting of Hello Pro Kenshuusei members: Rio Fujii, Ayaka Hirose, Minami Nomura, Rena Ogawa, Ayano Hamaura, Natsumi Taguchi, Sakurako Wada and Rei Inoue was announced. On February 25, 2015, the group name was announced as Kobushi Factory (Magnolia Factory) in light of Berryz Koubou's upcoming indefinite hiatus.

Former artists and groups
Leaving a subgroup or Hello! Project is referred to as graduating (卒業 sotsugyō). A graduation is a member's final performance either with Morning Musume or one of its many subgroups or associated acts, in which case they are either beginning a solo career or forming a new group within Hello! Project— or, rarely, leaving the Hello! Project umbrella entirely. These departures are usually voluntary and amicable.
The magazine Friday has, on three occasions, published photographs of Morning Musume members that have caused them either to quit the group or be fired. These members are Mari Yaguchi, Miki Fujimoto and Ai Kago. Because of these "scandals," and their subsequent sudden departures from the group, Mari Yaguchi and Miki Fujimoto are the only members of Morning Musume to have not undergone a "graduation ceremony" from the band before starting or resuming a solo career. Yaguchi was photographed with her then-boyfriend Shun Oguri in 2005, and although 22 at the time, she left voluntarily, stating that she could not maintain the "idol" image required to stay in the group. Yaguchi did have a graduation ceremony three years earlier when she departed MiniMoni, the subgroup she co-founded, in 2002, but did not receive another. Fujimoto was photographed with her boyfriend Shōji Tomoharu (whom she later married) in 2007. Ai Kago, although having a graduation ceremony from Morning Musume, did not have a ceremony for leaving Hello! Project, since her repeated scandals resulted in her contract being dissolved and later being fired from the agency.
All four of the main groups in Hello! Project (Morning Musume, Berryz Kobo, Cute and S/mileage) have all had at least one graduation within the group.
Conversely, Melon Kinenbi is the only (former) group in the history of Hello! Project to not undergo a graduation or other personnel change in its entire existence.
