About Ads
This app displays ads via Google AdMob, including a banner at the bottom of the screen. Free AI matches are limited to 5 per day; once that limit is reached, watching a rewarded video ad unlocks 3 additional matches. The trip description you enter is sent to Anthropic's Claude API solely to generate your match and is not permanently stored on our servers.

Why This App
Onsen etiquette is rarely written down anywhere a first-time visitor will actually see it before they're already undressed at the entrance, and the rules that do circulate online are often vague or outdated on points like tattoo policy. Onsen Manner starts from something any traveler can describe in a sentence - who they're with and what they're worried about - and turns it into a real matched bathing format and the exact etiquette sequence to follow, so a visit that could feel intimidating becomes a considered, comfortable part of the trip.
