Japan Onsen Atlas

National register

The number of onsen this atlas has collected and checked by name, prefecture by prefecture, beside official statistics from the Ministry of the Environment. These are coverage figures, not the total number of hot springs in Japan. We keep updating with the aim of covering every onsen in the country.

We do not claim "complete coverage". The official statistics are not a list of names, and collection by name is a separate effort.
