In Tokyo, many sento quietly allow tattoos.
In Osaka, most do not.
It’s not a cultural difference.
It’s a choice.
Don’t assume the same rules apply.

Radium Onsen Sinsekai
Right next to Tsutenkaku.
You’ll probably notice the tower first—
but right below it,
there’s a sento where no one cares about tattoos.
Tourist spot above.
Everyday life below.
Irifune Onsen
Another option is Irifune Onsen in Nishinari.
I tried to visit—
but it was unexpectedly closed.
So always check before you go.
