Japanese hot springs, checked properly.
Three things decide whether you can actually bathe in Japan: whether tattoos are allowed, whether there is a bath you can have to yourself, and whether you can go in without staying the night. We read the Japanese source and record what it says, with the date we checked it.

Onsen where tattoos are not a problem
Including places where the shared baths are off-limits but a private bath is not — the option nobody tells you about. See all 116 of them.

You can bathe without staying the night
Many ryokan open their baths to day visitors for a small fee. It is a normal thing to do in Japan and almost unknown outside it.

Every entry here was read in Japanese, from the facility’s own site or its city’s tourism office, and stamped with the date we checked it. When a place has not published something, we say so.
The editor’s ten
Every onsen on this list was visited in person. 2 places are still open — we have not found a number one yet.
