Hey Gucci,
Did you go to an onsen?
The reason I ask is you mentioned you have some tattoos and I heard they don't let guys or girls with tattoos into an onsen (or if you have a small tattoo you have to cover it up).
Tattoos are apparently still frowned upon in any public place in Japan because they are associated with yakuza, criminals etc.
Did you ever get hassled or asked to cover up?
