MOETAN

is a series of English language study aid published by SansaiBooks in Japan. Targeted at otaku, it attempted to teach English words using examples drawn from computer games and anime.

In the reprint of the first MOETAN book and the bath towel sold during Comic Market 69, MOETAN stands for 'Methodology Of English, The Academic Necessity'. The acronym may have been chosen as a play on combining the words moe and -tan, both terms of cuteness used in relation to girl characters in anime, to create a portmanteau ic double meaning. Bandai Visual, Planet Entertainment]], Actas Inc, Hakuhodo DY Media Partners Incorporated produced a television series based on the book. The TV series premiered on Chiba Television on July 8, 2007, followed by TV Kanagawa, TV Osaka, TV Saitama, and TV Aichi.
