Hot springs and public baths are a very popular part of Japanese culture,
but some facilities may refuse entry to guests with tattoos.
This rule comes from historical associations with organized crime groups,
and many traditional establishments still maintain these long-standing policies today.
In recent years, with the increase in international visitors,
more tattoo-friendly hot springs have started to appear.
However, checking the rules in advance is still very important.
If your tattoo is small,
you may be allowed to enter by covering it with special tattoo cover stickers or patches.
If you want to relax without worrying about others around you,
using a private bath (family bath / private onsen) at a ryokan or hotel is also highly recommended.
You can easily search for these places on travel websites or Google Maps
using terms like “Tattoo Friendly Onsen” or “Private Onsen.”
