Toyotomi Onsen Fureai Center
豊富温泉 ふれあいセンター（町営）
The town-run bathhouse at the heart of Toyotomi Onsen, Japan's northernmost hot-spring village, an hour by car from Wakkanai airport. The spring was struck during oil exploration in 1926 and still carries traces of petroleum — a rarity worldwide, with an oily smell and slippery feel. It is famed as a 'miracle bath' that draws people from across Japan seeking relief from atopic dermatitis and psoriasis. Besides the general bath there is a cooler cure bath for long soaks. Admission is a cheap ¥510; open 10:00–21:00 (last entry 20:30), closed every other Thursday. The canteen serves jingisukan lamb and set meals. Fit it into a far-north drive with the Sarobetsu wetlands and views of Mt Rishiri. About 10 minutes by bus from JR Toyotomi Station.

The town bathhouse of Japan's northernmost spa, famed for its oily water
Toyotomi Onsen, near the Sarobetsu wetlands at the northern tip of Hokkaido, is Japan's northernmost hot-spring village. It began in 1926 when hot water gushed out with natural gas during an oil test drilling; the water carries traces of crude oil, leaving an oily film and a petroleum smell — a spring type almost unique in the world. The Fureai Centre is the town-run day bath where you can try this water, listed among Japan's 100 famous springs, for ¥510. It is a special place, drawing long-stay visitors from across the country seeking relief from atopic dermatitis and psoriasis.
Moisturising water laced with iodine and oil
The water is an iodine-bearing sodium chloride spring (mildly alkaline, hypertonic); iodine and salt plus traces of crude oil give it a moisturising quality, as if coating the skin in a fine film. The smell and feel surprise at first, but most people notice how supple their skin feels afterwards. There are two kinds of bath — general pools at a comfortable heat, and cooler 'toji' cure baths for long soaks — so choose to suit your purpose. Because of the oil, it is good manners to follow the house guidance on how to wash, and entries are limited to two a day. As of September 2026 the centre notes that the water is temporarily being diluted owing to source conditions.
Practical details and cure-stay information
Hours are 10:00–21:00 (last entry 20:30), closed every other Thursday, with a maintenance closure in April. Adults ¥510, elementary ¥250, seniors 65+ ¥300. The sauna, massage chairs and paid rooms are currently suspended; the ground-floor rest hall (until 19:30) and the restaurant 'Ajisai' (Ezo venison dishes, jingisukan) are open. A concierge desk offers advice on therapeutic stays — consult them first if you are considering a long cure. Access is remote — 10 minutes by car from JR Toyotomi Station, an hour from Wakkanai Airport — but the village has several inns for cure guests, and a walk in the nearby Sarobetsu wetlands makes a good pairing. Check the latest calendar on the official site (toyotomi-onsen.com).
