I sadly cannot make it to this documentary premiere, but for folks in the general Tokyo area - my friend produced a documentary on queer folks in Japan.
The documentary most folks know about LGBTQIA+ people in Japan is Queer Japan which is good in its own right--it introduced a lot of the activists and pillars of the community that have been around for a long time in Ni-chome, the gay district of Tokyo. But queer folks aren't just in Ni-chome; and this documentary has a wider lens.
*To folks not in Japan -- if you're interested in spreading the word about this documentary they have an Instagram here to follow and share.
