What is Dake Onsen?

Only Once a Week! The Mysterious White Hot Spring Experience at Dake Onsen, Fukushima

Dake Onsen, located in Nihonmatsu City , Fukushima Prefecture , is a historic hot spring that is said to have been discovered over 1,200 years ago during the Heian period.

There have been many disasters in the past, including landslides and the Boshin War, and the area has been repeatedly destroyed or annihilated. However, each time the hot springs have been re-drained and rebuilt, and in 1906 the area was finally settled in its current location.

The temperature of the water at the source of the bath is over 70 degrees, but there is a secret as to why we are still able to bathe in it.

The water is drawn from the source of the hot spring over a distance of about 8km, and is naturally kneaded as it travels down the mountain, so that it arrives at the perfect temperature at the hot spring town.

However, if the approximately 8km of pipes are not cleaned regularly, they will become clogged with "yunohana" (sparkling mineral deposits) from the hot springs... That's where the "yumori" (guardians of the hot springs) come in.

The Yumori are people who are in charge of managing everything related to the hot spring source and the drawn water. They make sure the water flows smoothly and continue to weave the history of Dake Onsen.

The people who look after the bath periodically clean off the mineral deposits that have built up in the pipes. This process turns the clear, colorless hot spring water milky, creating the famous "Milky Days" of Dake Onsen.

On a milky day, the Dake Onsen has a stronger sulfurous scent than usual and the water is smoother. If you want to enjoy two Dake Onsen at once, you can stay overnight and enter both hot springs.

In principle, the baths are washed away once a week, usually on Mondays. However, as this is dependent on natural conditions, the dates of Milky Days are announced on the official social media accounts of the Dake Onsen Tourist Association.

Blessed with medicinal waters and abundant nature, Dake Onsen is also valued as a national health resort and is recognized as a healthy hot spring resort.
