Stop calling ahead every time. Every tattoo-friendly bath here comes with the source link and the date we last checked it. 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. ※To correct or remove a listing, contact support@kanauworks.com
