Chubu and Hokuriku in central Japan
For this map, Chubu and Hokuriku consist of seven prefectures: Shizuoka, Aichi, Gifu, Mie, Toyama, Ishikawa, and Fukui.
The Pacific Ocean lies to the south and the Sea of Japan to the north, with high mountain ranges between them. The region contains a wide variety of landscapes, from the coast to the mountains.
Explore Chubu and Hokuriku on the map and look for hot springs with me.
Explore the hot springs of Chubu and Hokuriku on the map
Select a ♨ marker to see information such as the hot spring or source name, recorded area, temperature at the time of investigation, pH, and sampling date.
You can also search by hot spring name, source name, or municipality using text, or use the microphone button to search by voice.
Compare the Pacific and Sea of Japan sides, and zoom in on places surrounded by mountains as you look for hot spring records.
About the map data
The ♨ markers represent historical records included in AIST’s Hot Spring Chemical Analysis Data. They are not a list of hot spring facilities currently in operation, and the dates of investigation vary by location.
A place without a marker does not necessarily have no hot springs. Each marker shows an approximate location and does not indicate the exact site of a spring or the entrance to a facility.
The displayed temperature was measured at the source and may differ from the temperature of the water in a bathing pool. The pH value is only a guide to acidity or alkalinity. Temperature and pH alone cannot determine a hot spring’s type or therapeutic effects.
How many hot springs are there in Chubu and Hokuriku?
According to the Ministry of the Environment, Chubu and Hokuriku have 429 hot spring areas and 3,695 hot spring sources. Together, they discharge 308,784 liters of water per minute.
The number of hot spring areas and the number of sources are not the same. A single hot spring area may contain multiple sources.
The data card lets you compare the region’s number of hot spring areas, total number of sources, and discharge volume with the figures for Japan as a whole.
What do you think about a region having more than 3,000 hot spring sources?
What I noticed while making the map
On the Chubu and Hokuriku map, hot spring markers appear across the region.
Gifu’s pattern caught my attention because it looks somewhat different from those of the other prefectures.
The distribution may also differ among the Pacific side, the Sea of Japan side, and the mountain areas.
Why not explore the map to find a hot spring in Chubu or Hokuriku that you would like to visit?

The data card uses Ministry of the Environment statistics, while the ♨ markers use AIST’s historical analysis records. The scope, reference date, and counting method differ, so the figures are not expected to match. Before visiting, check the facility’s or local government’s official information for its current location and operating status.
