Bourou Noguchi Noboribetsu

Bourou Noguchi Noboribetsu opened in June 2006 and marked twenty years in 2026. All 40 rooms are suites of 50 to 100 sq m, and every one has its own hot spring bath fed from the source — the house calls it a 展望風呂, an outlook bath — behind windows that open. The design is 和モダン, Japanese-modern, credited to the Hokkaido-born sculptor Takenobu Igarashi and architect Makoto Nakayama.

Of the nine spring types the inn counts in Noboribetsu, it draws the milky sulphur one: a sulphur-bearing sodium-calcium chloride spring, hydrogen-sulphide type, pH 5.3, 46.4°C, rising naturally at 607 litres a minute. The indoor bath’s windows are set low, filled by the garden once you are in the water; there is an open-air bath run free-flowing from the source, and a dry sauna with a cold plunge. Men’s and women’s sides do not swap, and no bath can be booked for private use. What can be booked is a 貸切岩盤風呂 — a private bedrock-bath room, heated stone rather than water — for an hour, 3,300 yen for two or 5,500 yen for four.

Dinner is a 和洋会席, a kaiseki that works French method into Japanese courses. Both meals are served in private dining rooms.

Check-in 15:00–19:00, check-out 11:00. The baths close for cleaning around midday and otherwise run through the night until 10:00. No guests aged 12 or under, and no pets. A paid shuttle runs from Sapporo Station and New Chitose Airport, booked direct seven days ahead.
