Thanks for replying, Dawni. I hope you understand this thread was not meant to belittle you or other you or criticize you in any way. It's something I'd been wondering about for years-- actually, ever since I first visited TG communities online and found them rife with manga/anime fandom. It's just that your posts showed the purest examples of the phenomenon I'd ever seen and prompted me to ask what's it all about. I felt slightly weird about asking because I remind myself a little too uncomfortably of the rubes who ask "What's this TG all about, anyway, I don't get it" which makes me feel objectified if it's done aggressively. I don't want to do that to anyone else.
But I'm wondering does this Japanophilia have any particular connection with TG, or is it widespread in general? I know lots of young people, but none of them who I know IRL are into this, just TG people I see online. I want to understand better, because if there is a particular nexus of Japanophilia or anime fandom with TG, it might be relevant to me.
Japanophilia isn't a new phenomenon-- the most advanced example of it I've ever heard of was a Greek-Irish journalist named Lafcadio Hearn, who first went to Japan in 1890, settled in, learned the language, became a naturalized Japanese citizen, changed his name to 小泉八雲 Koizumi Yakumo, and spent the rest of his life writing books about Japanese culture.
