Nichijou (lit. Everyday) is a Japanese comedy manga series written and illustrated by Keiichi Arawi. The manga began serialization in the December 2006 issue of Kadokawa Shoten’s manga magazine Shōnen Ace, and was also serialized in Comptiq between the March 2007 and July 2008 issues. Kadokawa Shoten later published all chapters of the series in ten tankōbon volumes from July 2007 to December 2015. Set in a suburban Japanese town, Nichijou is populated by an ensemble set of characters, featuring moments from their everyday lives which alternate between the mundane and the strange, without much focus on a narrative.
The manga and anime series were initially licensed in North America by Bandai Entertainment in July 2011, but both releases were cancelled due to the company’s downsizing. The manga series was later licensed for publication in English by Vertical, with the first volume released in March 2016.
Nichijou began as a manga series written and illustrated by Keiichi Arawi. It uses a combination of normal comic format and four-panel comic strips. Originally, the manga was meant to be a short, stand-alone series which was serialized in Kadokawa Shoten’s Shōnen Ace magazine between the May and October 2006 issues. Starting with the December 2006 issue, the manga began regular serialization in Shōnen Ace, and was also serialized in Kadokawa’s Comptiq magazine between the March 2007 and July 2008 issues. The first tankōbon volume was released in Japan on July 26, 2007. The manga series ended with its tenth volume, which was released on December 10, 2015, along with a limited edition commemorating the tenth anniversary of the series, which included a 120-page companion book.
Bandai Entertainment initially licensed the manga in July 2011, but later cancelled its release by October due to downsizing of the company. JManga, an American digital manga platform, was able to release the first four volumes of the manga through its website before shutting down in May 2013. The manga series was later licensed for publication in English by Vertical, which released all ten volumes in 2016 and 2017. Beginning in January 2012, the manga has been released in Finland by Punainen Jättiläinen under the name Arki, which is Finnish for “weekday”. It was translated into Finnish by Antti Kokkonen. The Nichijou manga series sold 1,005,300 tankōbon volumes in 2011, reaching 49th place in the year’s best-selling manga series chart released by Oricon.
Nichijou follows the everyday lives of various people in the town of Tokisadame, mainly focusing on the energetic Yūko Aioi, the bright and cheerful Mio Naganohara, the quiet and deadpan Mai Minakami, the anxious robot Nano Shinonome, her young creator the Professor, and a talking cat named Sakamoto, along with an ensemble cast of characters. Random and/or outlandish events regularly occur throughout the series, mainly through the mundane situations each character undergoes.
In the anime series, Nano receives the most prominent story arc out of all the characters; the first half of Nichijou pertains to her desire to become a student in high school, while the second half deals with her own fear of being revealed to be an android while at school with Yūko, Mio, and Mai. Vignettes which are mostly unrelated to the main focus of the series are placed throughout each episode, some of them adapted from Arawi’s manga Helvetica Standard.
