Back to the Future merchandise published by Takarajimasha
Takarajimasha released the Japanese version of the 30th-anniversary Back to the Future documentary, Back in Time, in 2016. It included a Japanese translation of IDW Publishing's comic story, "When Marty Met Emmett".
Takarajimasha also published IDW Publishing's Back to the Future trade paperbacks in Japan, under their Kono Manga ga Sugoi! Comics imprint, that retained the left-to-right reading style of the original comics.
In 2017, they published Back to the Future: Untold Tales. The Japanese version was organized so that every story was a chapter. For a limited time, the first five chapters were available as a webcomic that was viewable from Takarajimasha's website. Later that year they published the Japanese version of Back to the Future: Continuum Conundrum.
