Oh, and I just thought of a documentary that has a significant relationship to a currently airing Japanese drama.
The documentary: The Great Happiness Space
wrote: This compelling film explores the rarely seen world of Japanese host boys, men who are paid to entertain wealthy women in exclusive nightclubs. Almost but not quite gigolos, more akin to male geishas, the host boys of Café Rakkyo share their secrets with director Jake Clennell in his first documentary. The narrative focuses on Issei, Osaka's top host boy, but all the characters in this unique subculture are fascinating. (Source: Netflix)
For those of you watching the Ouran High School Host Club drama, I strongly recommend this documentary. I actually saw it a long time ago, before I was even aware of the anime, and I think it influenced how I understood the anime. There are a ton of Japanese dramas that involve hosts/hostess and/or their clubs. The ones that come to mind are Gira Gira, Misaki Number One, TEIOH, and Tsubasa no Oreta Tenshitachi, but there are many others.
