## What is Onsen Tattoo Map?

Standing outside a Japanese bath house, wondering whether you will be turned away.

Tattoo Friendly Onsen & Sento is a map that answers that before you go.

■ See where you can actually get in
・Onsen, sento and sauna from all over Japan
・Four clear states: Tattoo OK / Cover required / Conditional / Unverified
・Filter to show only the places that allow tattoos
・Private and reservation-only baths included, where nobody sees you at all

■ We show our sources
・Tattoo policies come only from what the facility or the local government publishes itself
・No blog roundups, no review-site hearsay
・Open the source page and see the last-verified date, for every single listing
・"Not mentioned" is never treated as "allowed". If we do not know, we say Unverified

■ Not only tattoos
・Accessible toilets across Japan
・Designated smoking areas, only the ones published by local governments
・Prayer rooms, mosques and halal-friendly restaurants on the same map

■ Five languages
・Japanese / English / Korean / Simplified Chinese / Traditional Chinese
・Switch anytime from the globe button on any screen
・A guide to Japanese bathing etiquette is included in every language

■ Keep track
・Save places you want to visit, and log the ones you have been to
・Everything stays on your device

■ Works with a bad signal
・All facility data is stored on your device, so it opens in mountain hot-spring towns and basements alike
・No account needed

■ Free to use
The map, the details, the sources and the languages are all free. Ads support the running costs. Pro is a one-time purchase that removes ads and makes saves unlimited. It is not a subscription.

※Policies change. Please confirm directly with the facility before you travel, especially in a group.
※Smoking area data is republished from local government open data and is not an encouragement to smoke.
