About the water
Tokachigawa's water is heated deep beneath the Tokachi plain rather than by a volcano, and rises through peat on the way up. Humic substances from long-decayed plants dissolve into it, giving a clear brown colour and a silky, slippery feel. It is weakly alkaline with salt and bicarbonate, and the inns like to compare it to a skin lotion. Posted indications include chronic skin conditions and poor circulation, which is not a guarantee of results.
Indications (as posted on the analysis)
Posted indications: neuralgia, muscle and joint pain, frozen shoulder, motor paralysis, stiff joints, bruises, sprains, haemorrhoids, chronic digestive and skin conditions, convalescence, fatigue, general health, gynaecological complaints, poor circulation, cuts and burns
Indications are an official statement based on the water analysis, not a guarantee of treatment. They are kept separate from opinions.

Three things not to miss
Photo information
The moor water itself
Every inn in the resort A weakly alkaline sodium chloride-bicarbonate spring carrying humic matter, 55–60°C at 500–700 m depth. Inns describe the water as feeling like a skin lotion.
Its colour and feel tell you at once this water did not come from a volcano.[1][2][6]

The story
From Otofuke River Bath to Tokachigawa Onsen
The earliest record, from 1874, calls it 'Otofuke River Bath'. In 1900 Ema Kahei began using the spring, and in 1913 Maeda Tomosaburo drilled into 30–36°C water and opened an inn. A 1928 borehole by Amemiya Komahei struck an abundant 42°C flow, and in 1933 the resort took the name Tokachigawa Onsen.[1]
Water made by peat
'Moor' is the German word for bog or peatland. Beneath the Tokachi plain lies a bed of peat built from ancient vegetation; water heated deep below passes through it and dissolves humic matter on the way up. That is how a plain with no volcano came to have a hot spring. The moor spring became a Hokkaido Heritage asset in 2004 and the name was registered as a regional trademark in 2008.[1][2]
A resort along the river
Eighteen inns with room for 4,200 guests a day line the left bank of the Tokachi River. In July 2020 the Garden Spa roadside station opened, bringing swimwear pools and footbaths that let non-residents try the moor water. In winter swans settle on the river and the Sairinka light festival glows on the snow.[1][4][5]

About 30 minutes by Tokachi Bus from Obihiro. Start in swimwear at the Garden Spa to get used to the brown water, then compare the feel in a hotel bath such as Kangetsuen in the afternoon. On a winter evening walk up to Sairinka in Tokachigaoka Park. The last bus back leaves at 18:55, so keep an eye on the clock.
