A 26-episode anime adaptation directed by Tatsuya Ishihara and produced by Kyoto Animation was broadcast in Japan between April and September 2011, after an earlier original video animation (OVA) was released in March. A PlayStation Portable game by Vridge and Kadokawa Games was released on July 28, 2011, entitled Nichijou: Uchuujin. Madman Entertainment licensed the anime series in 2011 for Australian and New Zealand distribution, releasing the DVDs in April and May 2013. Funimation released the anime on Blu-ray and DVD in February 2017.
Kyoto Animation adapted the Nichijou manga into a 26-episode anime television series directed by Tatsuya Ishihara and an original video animation (OVA) episode. The anime adaptation was first announced on May 22, 2010 through the July issue of Shonen Ace magazine. The OVA, titled Nichijou Episode 0, was bundled as a DVD extra with volume six of the manga series on March 12, 2011. The anime series aired in Japan on TV Aichi from April 3 to September 25, 2011 and was also simulcast by Crunchyroll under the name My Ordinary Life. The series was re-edited into twelve episodes for broadcast on NHK Educational TV in January 2012. The series also incorporates skits from Arawi’s other manga, Helvetica Standard, which is published in Kadokawa Shoten’s Newtype magazine. Bandai Entertainment had originally licensed the anime, but its release was later cancelled. However, Madman Entertainment managed to release the series in Australia and New Zealand in subtitles only. It was released as a two part collection containing 13 episodes each. The first part was released on April 11, 2013, while the second part was released on May 9, 2013. Funimation later licensed the series in North America and released it on February 7, 2017. A dubbed re-release by Funimation will be available on July 23, 2019.
The Nichijou anime has reportedly had low BD and DVD sales, and did not come close to meeting the break even line according to animation director Shunji Suzuki. The first DVD volume sold 924 copies in its first week of sales, while the second and fourth BD volumes sold over 2,000 copies each in their first week.
Anime News Network reviewer Carl Kimlinger gave the series a B, stating that the anime is a “slice-of-life comedy with a penchant for lunacy and a taste for huggable cuteness…”, giving praise especially to Kyoto Animation’s lively animation of the series: “a rare chance to see talented animators fully indulging their love of the art.” Fellow ANN reviewer Theron Martin stated in his review of “Nichijou Episode 1” that despite the series’ ability to entertain, it is “absolutely not a series for everyone”. Chris Beveridge of the now defunct Mania.com reviewed the first four episodes, giving each succeeding episode a lower grade (B for episode 1 down to D+ by episode 4). Beveridge stated in his review of episode 4 that “[Nichijou is] so full of fluff and pointlessness that it’s hard to get enthused about.”
- Yūko Aioi
- Yūko is an energetic 16-year-old high school girl with short brown hair. Her nickname is Yukko (ゆっこ). Because she is often too lazy to do her own homework, she always copies from either Mio or Mai instead. Although she is a generally an easygoing person, her mood changes instantly when she is insulted. She sometimes greets her friends with “selamat pagi” (Malaysian, Bruniean and Indonesian for “good morning”).
- Mio Naganohara
- Mio is a bright and cheerful girl, sporting light blue hair pulled into pigtails and held by two small wooden cubes (however, when at home or asleep, her hair is untied). She has a crush on Kojiro Sasahara. At first glance, she appears quite ordinary in comparison to her friends Yūko and Mai but actually harbors a very short temper, prone to tantrums and acts of violence in order to avoid humiliation; even assaulting a police officer to keep her yaoi manuscript from being discovered. She often has to humor Yūko to make her happy. Being a talented artist, she occasionally draws homoerotic pictures of Kojiro in her notebooks and, under a male pseudonym, has entered several erotic manga into contests that promise serialization to the winner. Near the end of the manga, Mio finally wins one of the contests she entered, though it is unknown whether or not she actually accepted the publisher’s offer due to her paranoia about her art. She is 16 years old.
- Mai Minakami
- Mai is a quiet and intelligent girl who wears glasses. Before the events of the manga series, Mai had lived in Alaska and moved to Japan due to her father’s job. She excels at a wide range of activities, including fishing, wood carving, and arm wrestling. Despite her serene and rather unemotional demeanor, she has a rather eccentric sense of humor, often frustrating her friends with her pranks. Her sometimes deadpan mannerisms often make people wonder what is going on in her head. She has two pet dogs named Oguri Cap and Pyon.
- Nano Shinonome
- Nano is an android schoolgirl, built by the Professor. Despite being a year old, she has the height and appearance of an average teenager. She worries about keeping her identity as a robot from other people, even though the large wind-up key on her back makes it quite obvious. Her limbs will sometimes fall apart, revealing items that the Professor installed into her system without her noticing, ranging from beam-firing weapons to Swiss rolls. She acts like the Professor’s caretaker, and spends her days helping her and doing all the household chores. Although she was technically never born, her “birthday” is March 7.
- The Professor is an intelligent eight-year-old scientist. She built Nano herself, and often makes various adjustments to her, but adamantly refuses to remove the wind-up key on her back because she thinks it is cute. Her favorite animal is the shark. She does not go to school, since she already graduated, and instead spends her days playing around in the house. Despite her intelligence, she acts like a spoiled child most of the time, as she throws tantrums to get what she wants. She likes snacking, playing around, and sharks. She also enjoys spending time with Nano’s friends, particularly Yūko due to her approval of “cool things” and Mai because she gives her shark-themed chocolates and drawings. She didn’t like Mai at first because she let her dogs corner her and Sakamoto on the street, but warms up to her when Mai draws a shark for her.
- Sakamoto is a black cat. He wears a red scarf made by the Professor, which allows him to speak. He was originally named Taisho and was the pet of Kana Nakamura until he fell out of the window of her house, and he was found by Nano before mysteriously turning up at the Shinonome home. He decided to stay with Nano and the Professor because of Nakamura’s constant unintentional neglect. In cat years, he is 20 years old, older than both Nano and the Professor, and tries to act like the adult of the house, but to his shame, he occasionally succumbs to his cat-like habits. A running-gag is his tendency to endure the Professor’s comically horrific physical abuse, usually in the form of a childish booby-trap or the rope noose she uses to walk him.
