Tweeted by actor/model Shogen, a 2019 film he stars in called “Okinawan Blue (Kokoro, Odoru)” — written and directed by Kishimoto Tsukasa (remember his name as he’s one to watch) — is available for streaming on Filmdoo.
Also streaming on Filmdoo is 2012’s “Karakara” a Canadian film written and directed by Claude Gagnon and one that I was able to watch at the Hawaii Film Festival. While not as Okinawan (lead actors are not Uchinanchu) as “Okinawan Blue”, at least the music is by one of my favorite musicians, Ara Yukito (Parsha Club).
You can also find other films (some of them are free!) from Okinawa that are (or aren’t yet) available on Filmdoo by creating a filter search on their website. Be sure to vote on the films you want to watch that aren’t yet available in your region!
