About Onsen Hopper
Onsen Hopper helps you find a hot spring in Japan you can visit for the day, without booking a room. Tap "Open now" to see which onsen near you are open right now, with last entry times. Each bath shows its entry price and opening hours, taken from the onsen's own website or an official tourism page, with the date it was checked. If a price or time is not published, the site leaves it out instead of guessing. You can search by area or on the map, and filter by outdoor baths, private baths, price under 1,000 yen, famous onsen towns and how to get there by train. It covers 1,475 day-use baths across Japan and 38 onsen towns. The whole site works in English and Japanese, and it is free to use.
- Who it is for
- Travellers and people living in Japan who want a hot spring bath for the day, without staying the night.
- Problem it solves
- Day-use onsen information is spread across many Japanese-only websites, and prices and opening hours are often hard to find or out of date. It is hard to know which baths near you are open right now.
- The solution
- Onsen Hopper lists 1,475 day-use baths in one place, in English and Japanese. Each bath shows its entry price and opening hours from official sources, and the Open now page shows which baths near you are open right now, with last entry times.
- What makes it unique
- Prices and hours come from each onsen's own website or an official tourism page, with the date they were checked. If something is not published, the site leaves it out instead of guessing.
