Onsen Guide

Onsen Guide is your calm, offline companion for Japanese public baths — the neighborhood sento and natural hot spring onsen, which share the very same manners.

No more guessing at the entrance. Follow a clear, illustrated walk-through of a real bath visit — from the shoe locker to the final soak — so you can relax like a local instead of worrying about getting it wrong. The same etiquette carries straight over to any onsen.
