Kyushu and Okinawa in southwestern Japan
Kyushu lies southwest of Honshu and consists of seven prefectures: Fukuoka, Saga, Nagasaki, Kumamoto, Oita, Miyazaki, and Kagoshima.
Farther southwest lies Okinawa Prefecture, whose many islands extend across the East China Sea and the Pacific Ocean. The region offers varied landscapes, including volcanoes, mountains, and islands surrounded by the sea.
Explore Kyushu and Okinawa on the map and look for hot springs with me.
Explore the hot springs of Kyushu and Okinawa 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.
Look beyond the main island of Kyushu to Okinawa, Tanegashima, Yakushima, and other islands.
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 Kyushu and Okinawa?
According to the Ministry of the Environment, Kyushu and Okinawa have 353 hot spring areas and 10,201 hot spring sources. Together, they discharge 723,122 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.
There are more than 10,000 sources but 353 hot spring areas. What do you make of the difference between these two figures?
What I noticed while making the map
The map includes hot spring records in Okinawa.
I was surprised to learn that historical hot spring analysis records exist on islands such as Tanegashima and Yakushima.
In Miyazaki and Kagoshima, the hot spring markers also appear to be concentrated in certain areas.
Zoom in and look for differences among the islands and prefectures.
Why not explore the map to find a hot spring in Kyushu or Okinawa 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.
