Tokachigawa Onsen: Day-Use Hot Spring Baths & Prices

At the heart of the Tokachi Plain, beside the Tokachi River, springs Tokachigawa Onsen. Its greatest feature is a plant-derived "moor spring," rare even on a global scale. Rising through a lignite layer where ancient plants accumulated, the water is faintly brown and soft to the touch, and in 2004 (Heisei 16) it was selected as a Hokkaido Heritage. There are two ways to bathe here — day-use bathing at the inns, and the spa at the roadside station where you bathe in a swimsuit — which gives you real latitude in how you build your trip.

Highlights

• A plant-based moor spring with the moisturizing feel of lotion
• A peaceful landscape overlooking the vast Tokachi Plain and its gardens
• The swans that arrive in winter and the Sairinka light event

Michi-no-Eki Garden Spa Tokachigawa Onsen, at the center of the hot spring town, is a complex facility gathering a spa you enter in a swimsuit or bathing garment, a marché, hands-on workshops, and four restaurants. Inside there is a free foot bath called "Sora no Ashiyu," and cosmetics such as moor-spring clay packs and hand creams are on sale as well. If you want to taste the water at an inn, Tokachigawa Onsen Dai-ichi Hotel Toyotei, which has the open-air bath "Takitsubo no Yu" set within a garden, accepts day-use bathers.

What the "Moor Spring" Really Is

"Moor" is a word derived from the German term for lignite and similar deposits. Long ago, reeds and other plants grew thickly along the banks of the Tokachi River, and over a great span of time they accumulated to form a lignite layer. The groundwater that wells up through that layer, richly containing plant-derived organic components, is the "moor spring."

The temperature is distinctive as well. In the center of the plain, such as central Obihiro, water rising from deeper than 1,000 meters underground is around 50 degrees; at Tokachigawa Onsen, water of 55 to 60 degrees comes from the shallow depth of 500 to 700 meters. According to the analysis figures published by the Dai-ichi Hotel, the spring quality is a sodium chloride and bicarbonate spring (weakly alkaline, hypotonic, high-temperature spring, pH 7.9), with a spring temperature of 54.8 degrees and a discharge of 670 liters per minute (mixed). The color is faintly brown and clear, and it is almost without taste or scent.

From a Meiji-Era Marsh to a Hot Spring Town

The oldest surviving description is a single line in the "Hokkaido Chishi Yoryo" of 1874 (Meiji 7): "Otofukegawa-yu, in Kato District, spring quality unknown." At that time this area was a marsh thick with reeds, where lukewarm water welled constantly from a small pond and, since it did not freeze even in winter, it served as a resting place for birds and animals. Among the Ainu people, it is said, there was a tradition of calling it "medicine water."

Its beginning as a hot spring was in 1900 (Meiji 33). Ema Kahei channeled the naturally welling lukewarm water into a box one meter square, heated it, and used it with his neighbors — that was the first instance. In 1913 (Taisho 2), Maeda Tomosaburo of Honbetsu dug by hand, struck water of 30 to 36 degrees, and built a two-story inn of 70 tsubo. This was the predecessor of today's Sasai Hotel. Then in 1928 (Showa 3), Amemiya Komahei succeeded in boring by machine and hit water of 42 degrees in abundant volume, which was reported prominently in the Otaru Shimbun of the day.

The name, too, went from "Shimoshihoro Onsen" by way of "Amemiya Onsen" to settle on "Tokachigawa Onsen" in the early Showa era. By around 1934 the number of inns had grown to four and the shape of a hot spring town was in place, and after the "Tokachigawa Onsen Hotel" served as the lodging place during the imperial tour of 1954 (Showa 29) and other such occasions, the name became known throughout Japan.

The Winter Festival of Light

The great attraction of winter is "Otofuke Tokachigawa Swan Festival Sairinka," held at Tokachigaoka Park. In 2026 it ran from January 24 to February 15, with the lights on from 19:00 to 21:00. The cooperation fee is 500 yen for junior high school students and above (300 yen for guests staying at Tokachigawa Onsen), and free for elementary school students and younger. About 100 free parking spaces are provided. Since it is an evening event, deciding on warm clothing and your ride home in advance is reassuring.

Enjoying the Seasons

From late January to late February the Tokachigawa Swan Festival Sairinka is held, where light art coloring the snowfield and the clear winter air feel magical. From spring to autumn, touring the nearby flower fields and gardens is delightful, and you can savor Tokachi nature along with that soft after-bath glow.

Practical Travel Notes

• Sairinka is a light event usually held from late January to late February at Tokachigaoka Park. Visiting during the evening lit-up hours lets you enjoy the light forms floating over the snowfield
• The roadside station next to the town has an attached moor-spring bathing facility, so you can try the signature faintly brown water without staying overnight
• The local bus linking Obihiro Station and the town is the basic public-transport route. Flower fields and gardens are scattered nearby, and with a car you can pair a visit with a rural Tokachi drive
• The best times are winter for Sairinka and early summer to summer, when the gardens flourish. A day trip of a bath and a stroll fills half a day, or reserve evening hours too if you include the event

A Quick Tip

Moor springs leave the skin soft and balanced, so avoid rinsing too hard afterward to keep the moisture. The faintly brown water is unusual, so scoop a little in your hands to check its color. Since Sairinka is an evening event, if you visit in winter, arrange warm clothing and return transport in advance.
