As the title suggests, the documentary “Queer Japan” is big and broad, not focused. A vigorous smorgasbord of sexual orientations and gender identities, Graham Kolbeins’ feature encompasses enough varieties of L, G, B, T and Q to leave you exhausted, and does so with energy, style and open-hearted appreciation.“Right now in Japan, we’re in the middle of an LGBT boom,” says a voice over an opening shot of Tokyo’s Rainbow parade, followed by another voice talking about the importance of becoming visible but “not generating any friction with the majority.” The film celebrates the boom, but its characters aren’t too concerned about the friction; with a couple of exceptions, they’re out and proud, with any days they might have spent in the.
