tengai makyou
Literally 'Devil's World Far from Heaven' (or possibly just 'Magic World Outside of Heaven'), is an RPG series very popular in Japan and Taiwan but virtually unknown in other regions. Tengai Makyou spans four official games and various side games, all of them parodying Japan in the fictional land 'Jipang'. The games usually humorize Western society's misconceptions about Japan, however The Apocalypse IV instead parodies Japanese misconceptions about America, and Oriental Blue is not really humor based.
Often known as Far East of Eden, however this is technically a sub-series within Tengai Makyou, as well as the name of a in-universe source material that the series is based on. However, the cancelled releases of Tengai Makyou all used Far East of Eden as the planned localized name. Only one game, Kabuki Klash (Shin Den), was released in English.
The series has similarities with Sakura Taisen as both have the same creator, and Red Entertainment has worked on both series.
