HarperVia will Publish The Tatami Galaxy Novel in English

Morimi's original novel was published by Ohta Publishing in 2005, with the cover illustrated by Ysuke Nakamura. Masaaki Yuasa created an 11-episode anime based on the novel in April 2010. According to Funimation, the plot is as follows:

College is full of opportunities to leave one's comfort zone. One third year student is constantly fantasizing about how his life might differ had he joined various campus circles—chasing, with mixed results, an idealistic rose-colored campus life where romance, friendships, and purpose fuse into a perfect university experience… at least until bad luck, questionable decisions, and dubious relationships enter the mix!

Funimation streamed and released the series on home video as it aired. Crunchyroll later streamed the anime, but it was removed from the platform in November 2018.

Tatami Time Machine Blues, the sequel novel, was released in July 2020, 16 years after the original novel. The novel is based on Makoto Ueda's stage play Summer Time Machine Blues. Morimi wrote the novel, and Ueda, Morimi's friend, is credited with coming up with the original idea. The sequel novel combines elements of the stage play's storey with Morimi's novel's characters. Nakamura was brought back to illustrate the cover.

Balistrieri previously translated Morimi's novel The Night is Young, Walk on Girl, which inspired a 2017 anime film directed by Yuasa and based on a screenplay written by Ueda.
