List of Yotsuba&! chapters
Yotsuba&! is a manga written and drawn by Kiyohiko Azuma, and published in Japan by ASCII Media Works in the monthly magazine Dengeki Daioh. Eighty-two chapters have been published; 81 of these have been collected in twelve tankōbon volumes, with further chapters appearing in Dengeki Daioh to be collected in tankōbon format over time. The series was licensed in English by ADV Manga, with five volumes published; volume six was scheduled to be published February 2008 but was delayed indefinitely. Yen Press announced at New York Comic Con 2009 that they had acquired the North American license for the English release of the manga; volume six was released in September 2009 along with new translations of the first five volumes, with later volumes to follow. The series has been licensed in France by Kurokawa, in Spain by Norma Editorial, in Germany by Tokyopop Germany, in Italy by Dynit, in Finland by Punainen jättiläinen, in Korea by Daiwon C.I., in Taiwan by Kadokawa Media, in Vietnam by TVM Comics, and in Thailand by NED Comics.
Yotsuba&! follows the daily life of a young girl named Yotsuba Koiwai and her adoptive father, with each chapter taking place on a specific, nearly sequential day of a common year starting on Wednesday. The year was initially believed to be 2003, coinciding with the date of the manga's serialization, but Azuma has stated that the manga always takes place in the present day. This allows the appearance of products created after 2003, such as the Nintendo DS Mr. Ayase plays in chapter forty-two.
Official story dates through volume five are given by a small artbook, Yotsuba&! Illustrations and Materials, distributed in Japan with volume six and Yotsuba & Monochrome Animals; dates from volume six on are established by evidence within the series, such as statements by characters, and by statements by Azuma. The collected volumes have seven chapters each, spanning about a week in series time. The first five volumes cover a summer vacation period.

|On the last day of the spring semester, Yotsuba and her father Koiwai move into their new house and meet the neighboring Ayase girls, Asagi, Fuka, and Ena. As the Koiwais settle in, they encounter problems, including a broken bathroom lock and Yotsuba needing to learn about polite greetings, air conditioners, and the proper uses of doorbells. Fuka offers the Koiwais her family's old television, and when Koiwai's friend Jumbo helps carry it, the Ayases are impressed by his height. For other household goods, Koiwai takes Yotsuba shopping at a department store for the first time. Jumbo takes Yotsuba and Ena cicada-catching, and they return to show off their catch to Mrs. Ayase. The next day, after Fuka helps Yotsuba bring in the Koiwais' forgotten laundry, Yotsuba plays in the rain.|

The next day, Mrs. Ayase sends Ena, Miura, and Yotsuba to buy cake from a bakery. After working all night on a deadline, Koiwai falls asleep, leaving Yotsuba to watch the house on her own. In a failed attempt to get closer to Asagi, Jumbo takes Yotsuba, Fuka, and Ena swimming at the pool. When Yotsuba catches a bullfrog, Ena adores it but Miura is frightened of it. Asagi returns from an Okinawa vacation with souvenirs for her family—and leftover sata andagi for Yotsuba.|

While helping Fuka shop at Jumbo's flower shop, Yotsuba buys all the leftover stock for ¥10. The next day, during Obon, Koiwai sends Yotsuba, dressed as the "Flower Cupid," to give away excess flowers. The next day, Koiwai takes Yotsuba on her first visit to a zoo to see an elephant.

After Ena takes Yotsuba to radio exercises for the first time, she invites Yotsuba over for breakfast, where Yotsuba decides to become a newspaperman. Her career ends, however, when The Yotsuba Times publishes the secret of Fuka's heartbreak to the rest of the family. After dreaming of being a tsukutsukubōshi, Yotsuba dresses up as one, only to learn that they are not summer-ending fairies but a type of cicada.|

Yotsuba helps Mrs. Ayase with household chores and then meets Koiwai's kōhai, Yanda, whom she instantly dislikes. To help with Ena's homework, Jumbo takes her, Miura, Yotsuba, and Fuka stargazing. During rainy day errands, Yotsuba misinterprets Koiwai's excuse for not going to the ocean, "There'll be jellyfish!" as a promise to go see the jellyfish, and invites Ena and Fuka along. When she throws a tantrum, he gives in and the four spend the afternoon at the beach.|

|On the last day of summer vacation, as Miura desperately finishes her homework, Yotsuba gives herself the assignment of constructing a utility shirt out of recycled materials. Koiwai takes Yotsuba shopping for a bicycle. After a few falls, she learns to ride it and uses it to accompany Asagi and Torako on an errand. Yotsuba tries out more careers, first as an office worker by writing memos, then as a milkman, delivering a bottle of milk to Fuka at her high school. For riding off without permission, Koiwai takes away her bicycle privileges, but after she helps him and Jumbo build some bookshelves, he restores them.|

|Ena and Miura show Yotsuba how to make a paper-cup telephone, which they string between Koiwai's office and Fuka's bedroom, and then take her on a bike ride to the playground of their elementary school. Because of Yotsuba's continuing interest in how milk is produced, Koiwai plans a trip to a farm, but this is put off when she gets a fever. Yotsuba helps Fuka and Fuka's classmate (Hiwatari, nicknamed Miss Stake) bake an elaborate cake as practice for their school cultural festival. When Koiwai wants instant ramen for lunch, Yotsuba insists on running the errand by herself for the first time. Koiwai, Jumbo, and Yanda take Yotsuba on her long-delayed farm visit, where she meets sheep and learns how to milk a cow.|

|Still excited from her trip to the dairy farm, Yotsuba brings the Ayases a souvenir of butter toffees and is fascinated by Mrs. Ayase's mail-order catalog. The next day, Mrs. Ayase tells Koiwai about the cart-pulling festival the following week, while Yotsuba confuses him with her "opposites game." When he takes Yotsuba out for lunch, Yotsuba runs into Torako and manages to order for herself. Yotsuba and Koiwai attend the cultural festival at Fuka's high school, where Yotsuba is disappointed with the plain pound cake her class serves. Yotsuba is excited by her first typhoon, and insists on going next door in the torrential downpour. When Fuka warns her that she will fly away in the wind, Yotsuba goes back outside to test this. Jumbo babysits Yotsuba while Koiwai is out, and when Yanda shows up to eat his instant ramen, he helps Yotsuba defends the house from the "intruder". Yotsuba and Ena help pull a children's cart in the aforementioned festival, where Yotsuba is visibly impressed by the happi, the taiko drum, Jumbo's tengu costume, exposed butts, and the amount of candy she receives. Koiwai takes Yotsuba shopping for autumn clothes, but when they pass a park she insists on collecting as many acorns as she can.|

|While Koiwai works, Yotsuba plans out a schedule for the day, but immediately falls behind and plays with her acorns instead. The next day, Dad takes Yotsuba shopping for a coffee maker at a mall, and while there buys Yotsuba her first teddy bear, which she names Juralumin. The next day, she shows Juralumin to the Ayases, who give Yotsuba Ena's old wagon to carry it in. To help Fuka study, Yotsuba brings her a mug of her father's coffee, but spills it on the table. One of Jumbo's customers invites him to her yakiniku shop's half-off night, and he brings Yanda and Koiwai along. When Yotsuba again drops the coffee she tries to bring to Fuka, the Ayase sisters visit her house. While there, they clean up and Asagi invites Yotsuba and Koiwai along to a hot air balloon festival the next day. The Koiwais, Asagi, Ena, and Torako get up before dawn to drive to the festival, where they watch the balloons inflate and take off on a race. After breakfast, they ride in a balloon, play with hand helicopters, and collect candy thrown by a paraglider.|

While Koiwai works, Yotsuba plays house with her wooden blocks, then talks her father into a game of hide and seek and playing on the swings in the park. Inspired by a picture book, Yotsuba learns how to cook pancakes from her father, with assistance from Yanda. That evening, the Koiwais show Jumbo photographs from the hot air balloon festival. While her father finishes an assignment, Jumbo babysits Yotsuba and gives her a book about animals. The next day, Jumbo takes the Koiwais shopping for a digital camera. While the adults compare cameras, Yotsuba explores the electronics store with Fuka. When Yotsuba lies about breaking some dishes, Koiwai takes her to a guardian Niō statue at a Buddhist temple to scare the "lying bug" out of her. When Yotsuba and Ena visit Miura's apartment, Yotsuba is upset when she sees her empty cardboard robot costume. To reassure her that the robot is not dead, Miura puts the costume on and plays with her in the park.

Yotsuba goes to an udon shop without her father's knowledge, and is allowed to watch udon being made. After getting a pizza menu in the mail, the Koiwais order a couple, though one turns out to be too much for Yotsuba to hold. After an announcement of an upcoming camping trip, Yanda arrives with various bubble-blowing devices, which they play inside, then outside, with. Yotsuba, Fuka, and Miss Stake (Fuka's classmate from chapter 45) go to a shrine to pick chestnuts, and Yotsuba learns about burr covers and bug infestations. Koiwai gives Yotsuba her own camera, which she uses to go around taking pictures of people. Yotsuba meets Miura at her apartment building, and they go to Ena's. On the way, a dog grabs her teddy bear and shakes it, making it smell like dog, so they wash it and dry it at the Ayases'. As a result, the bear's ability to speak is broken, so Asagi offers to repair it overnight. Yotsuba spends much of the intervening time sulking about Juralumin's absence until Yanda finally gets a reaction out of her. She goes to the Ayases', where she finds Juralumin repaired.

|A short opening sequence shows Yotsuba drawing Danbo in chalk on the street before noticing migrating geese flying overhead. She welcomes Torako to the Ayase household where she shows off her photographs and learns to tie a bow. After arriving to the flower shop too late to help Jumbo paint a desk, Yotsuba finds a can of blue paint in the shoe rack at home and paints a kitchen table while her dad is working, staining her hands and leaving drips and blue footprints throughout the house. She futilely tries to clean up the mess and is confronted by her dad, who laughs instead of scolding her. Before Mr. Koiwai shows her how to use paint thinner, they go to the grocery to purchase ingredients for mapo tofu and a helmet from the bike shop. On Halloween, Fuuka and Miss Stake dress Yotsuba as a pumpkin, explaining how to ask for candy before also dressing in costume to go trick-or-treating together. Early the next morning, Miura's mom and Ena's parents see them off for a camping trip organized by Jumbo and Koiwai. Yotsuba is unpleasantly surprised to learn that Yanda has invited himself along, but ends up laughing at his jokes on the journey. At the campsite, the girls help pitch the tent, rest in a hammock, and cook curry for lunch. For dinner, they grill the meat given as a present by the parents and Yotsuba wakes early the next day, surprised by the sunrise simultaneous with the moonset.|

|Yotsuba heads over to the Ayase house early in the morning, where she shows off her souvenirs and demonstrates the sleeping bag for Asagi. Because her dad says he is too busy, Yotsuba bullies Fuuka into taking her to the park, where they meet her friend Mii and play in the sandbox, making taiyaki and pudding with sand molds. After her dad puts her to bed, Yotsuba wakes up and explores the dark house before finding her father working. The next morning, Ena helps Yotsuba decorate the house for her grandmother's visit before Yotsuba and her father meet her grandmother at the train station, who Yotsuba attempts to greet with a headbutt. Once they are home, Yotsuba receives souvenirs from her grandma. In the morning, Yotsuba helps her grandmother clean the street in front of the house and later, they clean the house once her grandmother believes Yotsuba is taking cleaning seriously. Yotsuba and her grandmother practice origami with Ena and run errands together before her grandmother has to leave, which Yotsuba attempts to prevent by hiding her luggage. The next day, Yotsuba is sweeping the street in front of the house when Yanda arrives and helps himself to the grilled onigiri Yotsuba had made with her grandmother; at bedtime, Koiwai transforms into Sleepyman to put Yotsuba to sleep.|

|After helping Koiwai move a new table upstairs, Jumbo presents Yotsuba with a set of beads; an intense necklace-making session ensues for the trio. Miss Stake invites Fuuka and Yotsuba to join her for a free trial session of yoga; as the older girls struggle, Yotsuba exhibits astonishing flexibility. Yotsuba reads the story of Cinderella; inspired, she ties ribbons to her hair and is infuriated when Koiwai fails to see her fancy long hair. Going next door, Asagi immediately recognizes her as a princess and makes a fancy dress for Yotsuba using plastic trash bags; after she returns home for her bead necklace, Koiwai makes up for his earlier faux pas by asking the self-proclaimed Princess Zapunzel for a dance. The day before their trip to Tokyo, Yotsuba asks her neighbors and friends for places to go; Mother Ayase suggests Ginza, Asagi suggests Shibuya and Shinjuku, Ena suggests Tokyo Tower, and Fuuka suggests Harajuku specifically to eat crepes, which she calls stylish. Torako suggests Daikanyama but then gloomily asserts there are no fun places for kids in Tokyo. To prepare for their trip, Koiwai buys a smartphone and Yotsuba accompanies him to buy a sushi dinner at the market. Jumbo and Yanda visit later that evening to help Koiwai with his new phone and ask Yotsuba where she would like to visit when they arrive in Tokyo. At the train station, Yotsuba helps Koiwai buy a ticket and they board a train to Ikebukuro Station, where they transfer to the JR East Yamanote Line. The pair stop in Harajuku for cotton candy and crepes, and then Koiwai gets a text message from his sister Koharuko suggesting they all meet in Yoyogi Park. At the park, Yotsuba spies on three women dressed as aliens, who she successfully convinces to not destroy the earth. Koharuko reminds Yotsuba they traveled to Tokyo to pick up Koiwai's new car, a Mini convertible, and takes them to a buffet at a luxury hotel restaurant for lunch. After a filling meal, Yotsuba and Koiwai set off for the highway in their new car.|
