Alas, haven't seen any (and it'd probably be rude of me to take pictures of them!). Pandas sound more Chinese to me; if you'd like to get an idea of Japanese bears, there's an anthology called Massive: Gay Erotic Manga and the Men Who Make It that might be of interest. Gengoroh Tagame's work is superlative; several of his collections are available in English as well. Finally, you could try to find old issues of G-Men, Samson, and other gay men's magazines that specialize in bears, chubs, and the like. Oh, and the Tokyo and Osaka Eagle bars have Instagram, as does Shirokuma, a bear bar in Tokyo.
