I've been to a supposedly regular public onsen in Osaka in 2018 called Kompira where customers are mostly if not totally gay. There were had quite a lot of discreet action going on here and there in the hidden areas and corner. Guys sit in the pool and just feel up one another in the water. I had quite a a bit of handjobs and oral. Think the owner definitely knows whats going on but they don't seem to care. Very local and old feel. Mixed crowd from young to very mature. Tattoos allowed - i have several palm sized tattoos on my back.
Wow, I didn’t think if anyone has been to the place. Lol I’ve been to Kompira and I like the place too, but I have some concerns.
The place is family owned and the original owner is very old, so their son/grandson sometimes help to run the place. Apparently, the son/grandson are not tolerant to what’s happening inside and they sometimes call the police. I read they called the police a few times this year. I also heard the they tend to show up early in the evening, so maybe you should get there after 8-9pm.
And Kompira is not a tourist friendly place. You have to bring your own towel and shampoo/soap —technically you can rent it but what they have is more like a cloth. And the reception is very rude to everyone.
Anyway, I didn’t mention about the place because I can’t be responsible whatever happens. And the place is not legit gay sauna anyway. Lol
