A “moor onsen” rare even by global standards, it is said to make skin silky and smooth.
Tokachigawa Onsen is located in the center of the vast Tokachi Plain that takes up 10% of the total area of Hokkaido, and is a major hot spring in eastern Hokkaido, with about 600,000 visitors per year. This onsen is also said to have once been known as the “moor of healing” by the Ainu people, and development on its began in earnest from the beginning of the Showa Period. It was selected by Hokkaido Heritage in 2004.
The main characteristic of this onsen would have to be its title of “moor onsen”, where its water quality is combined with lots of plant-based organic matter.
In ancient times, the plantlife growing along the banks of the Tokachigawa River such as reeds etc. gradually accumulated over many years, and through the waters of the onsen gushing up through the layer of lignite this left behind, this has resulted in an onsen which includes a large amount of plant-based organic matter, a rarity even by global standards.
There are plenty of hotels and ryokan at Tokachigawa Onsen, so you can enjoy the moor onsen to its fullest. Most of these places allow single-day entry to the hot springs without an overnight stay. We also recommend touring around several different onsen.
