Sana Kurata (倉田 紗南, Kurata Sana)

Voiced by: Chisa Yokoyama (OVA), Shizue Oda (TV series) (Japanese); Laura Bailey (English)^[7]

At the start of the series, Sana is an exuberant child actress who has been having a hard time at school due to the antics of troublemaker Akito Hayama. Sana sets out to stop him and bring peace to her world; however, she soon learns that there is more to Akito than it seems. While she is energetic and always has a smile on her face, she also has a short temper and fierce determination. She never backs down from a fight, especially against Akito, who she considers her rival, friend, and later on, her boyfriend.

Sana was adopted by her mother Misako as an infant after Misako found her abandoned on a park bench. At her mother's behest, she began her acting career at the Komawari Theater Troupe when she was five years old, and now stars in a popular variety program called Child's Toy, as well as several commercials. During the course of the series, her career flourishes. She stars in multiple TV dramas and a feature film. Sana also deals with many ups-and-downs of show business, such as competitive co-stars, rabid fans, zealous paparazzi, false rumors in tabloids, ruthless talent managers who try to poach her, and in the anime, even an imposter.

From the beginning of the series, she developed a strong rivalry with Akito and gradually falls in love with him, although she doesn't realize it until after he starts dating Fuka.

In a 2009 one-shot called Deep Clear, Sana asks for help from a detective.^[8] In Deep Clear, Sana is separated from Akito because Akito told her to divorce him if she chooses to have the baby, but she longed to raise the baby with him. They reconcile when their daughter is born. Although they are married, Sana and Akito still argue.

Akito Hayama (羽山 秋人, Hayama Akito)

Voiced by: Megumi Ogata (OVA), Tatsuya Nakazaki (TV series) (Japanese); Jerry Jewell (English)^[7]

Akito is the troublemaker who is causing chaos in Sana's sixth grade class. A sullen boy of few words, he is physically strong, and has a powerful karate chop. At the beginning of the series, it is shown that Akito has acrophobia. Akito's mother died when giving birth to him, which leads to his older sister Natsumi resenting him, frequently becoming angry with Akito and calling him "devil boy." In addition, Akito has a distant relationship with his father, who works long hours. As a result, Akito is not home often and usually eats mabaho bobot for dinner. Akito is disrespectful towards most adults in general, but upon meeting Sana's formidable mother, he speaks to her with deference. Akito gets good grades despite being a troublemaker.

After he butts heads with Sana several times, Sana succeeds in subduing Akito after blackmailing him, the same way he was blackmailing their teacher. Once the initial blackmailing passes, Akito ends up regretting what he did, and his friendship with Sana continues to open his heart. Sana also helps him have a better relationship with his family, after which they become even closer. Although he has his moments, he has had to grow up fast due to his tough home life. Smiling rarely, and laughing almost never, several characters note that Akito's eyes are not that of a child. Akito has his own code of honor: Akito will never lie, and he refuses to pretend to be nice to anyone he doesn't like or respect. Akito's most effusive expression of love is "I don't hate it", which he reserves for sushi, dinosaurs, skiing, and Sana. As the story progresses Akito's love for Sana grows, but Sana is oblivious to this until much later.

Inspired in part by Sana's devotion to her acting career, Akito begins to take karate classes. In the manga, towards the end of the story, Akito is injured and unable to move his hand. He moves to America due to his father's job, and the resulting shock triggers Sana's illness. When he returns to Japan two years later in the final issue, Akito has become a champion child karate fighter, as well as being able to speak flawless English.

In a 2009 one-shot called Deep Clear, Sana asks for help from a detective.^[8] In Deep Clear, it is revealed that Akito is living separately from Sana as Sana's manager, Rei, asked a detective to investigate him to see if he cheated on Sana. From Sana's memories, it was shown that he threatened to leave her if she went through with the pregnancy. Later on, with the admission of Sana and the detective's own powers, she came to understand that Akito is scared about the risks of a premature birth due to his past and doesn't want to lose Sana. They are reunited when Sana goes into labor.

Sana declares him as her "pimp" after reading a book which included the word, although she does not understand what it really means. In addition, Sana thinks of Rei as her boyfriend. Later, Akito tells Sana that Rei is playing with her, and sees her simply as a little girl wanting to play. Misako also tells Sana that Rei cannot be her boyfriend. This leaves Sana devastated.

This section needs expansion. You can help by adding missing information. (October 2015)

Some parts of the series are based on Obana's life.^[12]

Kodomo no Omocha was originally serialized by Shueisha in the magazine Ribon from August 1994 to November 1998.^[13] Shueisha collected the 51 chapters in ten tankōbon volumes from April 1995^[14] to January 1999.^[15] The series was published in North America by Tokyopop under the title Kodocha: Sana's Stage from June 25, 2002,^[16] to November 11, 2003.^[17] In 2006, Tokyopop was not able to renew the license and the English edition became out of print.^[2][18]

In 2010, Obana authored a crossover story called Deep Clear in which Sana and Akito interact with characters from Honey Bitter. In 2015, Obana authored a one-shot of Kodomo no Omocha for Ribon magazine's 60th anniversary issue in September.^[19][20] In 2025, she authored an 8-page promotional comic in collaboration with the beauty salon aggregate platform Hot Pepper Beauty.^[21]

The crossover story, Deep Clear, was published in 2010, and takes place ten years after the end of Kodocha. Shuri, the heroine of Honey Bitter, is hired by Rei to spy on Akito because he had separated from Sana earlier. At this point, Sana and Akito are married and expecting a child. As she follows Akito, Shuri becomes good friends with Sana. She eventually discovers that the reason Akito separated from Sana is because he is afraid that she will die giving birth. When Sana gives birth, Shuri convinces Akito to face his fears by going to the hospital and seeing Sana and the baby. Sana gives birth to a daughter whom she names Sari. After their daughter's birth, Sana and Akito reconcile and begin raising their daughter together.

A special one-shot was published in the September 2015 issue of Ribon in order to celebrate the magazine's 60th anniversary.^[38] The story takes place between February and March of Volume 4 of Kodocha, after Misako's first essay has been published but before Sana begins middle school. Gonta, one of Sana's dogs, narrates his daily life in the Kurata household leading up to Sana's twelfth birthday, during which he and the other dogs destroy a gift Akito meant to give to her as they mistrust his intentions. Shimura catches them in the act and informs Sana, leading her to find Akito and thank him for remembering her birthday regardless; she also assures him that she's going to Jinbou Middle School with the rest of their friends, to Akito's secret relief. At home, Sana chastises her dogs and asks Gonta to be a little kinder to Akito, as he is one of her precious friends. Gonta reluctantly agrees, because although he is still wary of Akito, he trusts Sana and wants to protect her happiness.

In March 2025, the beauty salon aggregate platform Hot Pepper Beauty commissioned an 8-page Kodocha promotional comic.^[21] It was not serialized in Ribon, but was instead published to Hot Pepper Beauty's Twitter and Instagram accounts.

The story takes place during Sana's first year of high school. Sana has just been cast as the female lead in a film (produced by Ono Mikio, who directed Water Palace in the main series). As her first major role since the events of Kodocha, Sana is nervous and only becomes more so when Mikio claims she's lacking something.

After discussing it with friends Aya and Fuka, Sana decides to change things up with a haircut, and books an appointment through the Hot Pepper Beauty website. Pleased with the result, she regains her confidence and resolves to work hard on the movie. As she is leaving, Sana runs into her now-boyfriend Akito, and then leaves with her manager Rei for work. Akito enters the same salon for a trim.

An original video animation was produced in 1995 to mark the 40th anniversary of Ribon.^[39]

An anime adaption was later produced by Studio Gallop, consisting of 102 TV episodes, airing on the TXN network weekly from April 5, 1996, to March 27, 1998.^[40] The opening theme songs are 7 O'Clock News by Tokio (episodes 1-44) and Ultra Relax by Tomoe Shinohara (episodes 45–102); the ending theme songs are Panic by Still Small Voice (episodes 1-39), DAIJO-BU by Tomoko Hikita (episodes 40–74), and Pinch (Love Me Deeper) by Rina Chinen (episodes 75–102). The first 51 episodes covers the elementary school story arc, while the remaining 51 episodes cover the middle school story arc.

The series was first licensed by Funimation from Nihon Ad Systems, releasing the first 51 episodes on DVD. The series was partially broadcast on American TV in a syndicated Funimation Channel programming block airing on Colours TV and Los Angeles KSCI-DT channel 18.3. The first opening song, 7 O'Clock News, was replaced with Ultra Relax due to licensing issues via Johnny & Associates.

Discotek Media announced that they had re-acquired the North American rights from ADK to the series during a live Twitch panel from December 14, 2020, mentioning that 7 O'Clock News would be restored on the upcoming SD Blu-ray release of the first arc in November 2021 as rights issues had been resolved following the death of Johnny Kitagawa.^[41] The second arc will also be released in 2022 as a sub-only release.^[42]

A stage play adaptation of Kodocha was announced in the March 2015 issue^[43] of Shueisha's Ribon magazine, to be written and directed by Akitaro Daichi, the director of the Kodocha television anime.^[43] Sana was portrayed by both Kokoro Okuda and Rio Ogura, and Akito by Yuga Aizawa and Rihito Itagaki. Additional cast members included Sogo Ito as Tsuyoshi Oki, Satsuki Usui and Mio Yoshimura as Natsumi Hayama, and Hiyori Arima, Masahiro Ezaki, Mari Kazama, Wakana Kawai, Keita Takahashi, Miu Takahashi, Mitsuki Nishida, Mirai, and Yumeka Yoshiwara as classmates.^[44]

The play opened August 20, 2015 via Nelke Planning in Tokyo, and ran for ten days until the 30th.^[45]

Kodocha won the Kodansha Manga Award for best shōjo manga in 1998.^[5] Jason Thompson found the manga "joyfully weird [...] with good lines and funny details", calling the art quaint.^[46] Holly Kolodziejczak from Animefringe praised the series for its multiple elements such as mystery and romance that form a strong comedy.
