Tokachigawa Onsen

A spring drawn through peat

Tokachigawa sits on the wide Tokachi plain, eight kilometres east of Obihiro, where the agricultural settlements of the Meiji era took shape on land the Ainu had long known for a "medicine bath" along the river. The first written notice appears in an 1874 Hokkaido gazetteer; the modern resort traces to 1900, when a local farmer, Ema Kahei, piped a warm seep into a wooden box and shared the bath with his neighbours. Hand-dug drilling in 1913 brought up water at thirty-odd degrees, and the riverside village began to fill with inns.

What sets the place apart is the water itself. Millions of years ago this plain lay under an inland bay; the wetlands left behind compacted into deep beds of peat and lignite, and groundwater warmed at the bedrock rises back through those plant-rich layers carrying dissolved humic substances. The result is a mōru-sen (モール泉, from the German Moor for peat), a vegetable-organic-rich water of a kind so rare that for most of the twentieth century only Tokachi and Baden-Baden were said to produce it. Hokkaido designated it a Hokkaido Heritage in 2004 and the local tourism office has long marketed it as the prefecture's premier 美人の湯, "Beauty Bath".

Brown water, cold-air country

The bath itself runs tea-brown to amber, faintly oily on the skin, and almost odourless. Roughly fifteen ryokan line the south bank of the Tokachi river and pipe the same source: large dayuse halls at houses like Kangetsuen, Daiichi Hotel and Daiheigen, smaller family ryokan in between. The setting is plain rather than mountainous, a flat agricultural country that turns sub-zero by mid-December. From late November through March, whooper swans winter on the river within walking distance of the inns; the Hakuchō Festival "Sairinka" has illuminated the riverbank in their honour every winter since 1992.

Obihiro on the side

The nearer city of Obihiro carries its own appetites. Butadon, the charcoal-grilled pork bowl, was invented here in the 1930s and is still eaten as a local staple. Obihiro is also Hokkaido's confectionery capital, home to Rokkatei and its Marusei butter sand, and in summer the gardens of the Hokkaido Garden Path — Tokachi Hills foremost among them — open on the plain a short drive from the bathhouses.
