One of the most bizarre things that has happened in the entire adult industry in Japan, a situation I never expected to see, is Yakitate Japan, which in 2002 gained a manga adaptation, then an anime, then an official hentai doujin and now an adult film based on the doujin.
Below is the cover of the doujin:
Official JAV of Yakitate Japan is Released
The film is supposed to adapt the two volumes of the Yakitate Japan doujins, which were officially released by the author himself or his assistant (the information about the authorship is minimal). Adding extra scenes.
The film stars actresses Misono Waka, Kuramoto Sumire and Himeno Ran, and it has a total of 90 minutes of lots of Ousama Game action. The film code is DASS-590.
