The Japanese comics and animated movie industries — producing manga and anime, respectively — delivers a lot of transgender erotica. The problem is to find it and, for the Non-Japanese, to read it.
Fortunately, there are sites out there that try to help us in this respect. Jana’s TG Manga and Anime is one of them.
The site contains long lists of TG related content. It does not lead you to the comic strips or movies themselves, though. In order to find them, you will have to make use of other sites.
“If you want to get general information about the titles listed here, you must try in other sites, here the information will center only in the TG content in the different titles.”
This means that the site brings newcomers only one step of the way. Jana does provide links to other online resources on the home page though, sites that might help you find the gems she is recommending.
The site is a little bit hard to navigate. Here is a link to the list of titles.
