Kashoutei Hanaya

Kashoutei Hanaya is a four-storey inn of 21 rooms in Noboribetsu Onsen. Eight room types run from plain tatami rooms of six to ten mats — toilet and washbasin, no bath or shower — up to a 45 sq m executive-floor suite with the inn’s only balcony. Every room has been non-smoking since April 2020.

The water is an undiluted, free-flowing sulphur spring drawn from Jigokudani, the “Hell Valley” steam field a kilometre away: acidic, hydrogen-sulphide type, milky and faintly cloudy, 65.8°C at source. One indoor and one open-air bath serve each sex, the open-air one beside the Kusurisanbetsu River; neither can be reserved for private use. Bathing is open around the clock except 01:00–04:30 for cleaning. Yuno-hana (湯華), the mineral flakes the spring sheds, settles on the tub floor; stir it and the water turns white.

The inn’s own pages disagree about guest-room baths: its rooms page lists a 34 sq m Japanese-Western room, “Botan”, as having a natural hot spring bath, while its FAQ states that no guest-room bath is hot spring water. Neither claims any room has an open-air bath.

Dinner and breakfast are both brought to the room, dinner starting 17:30–19:00 and breakfast 7:00–8:45. The 会席 (kaiseki) menu changes every three months and is served on the house’s own Arita ware. Check-in is 14:00, last arrival 19:00; check-out is 11:00. A free shuttle meets JR Noboribetsu Station if booked by 22:00 the day before. Bathing tax of 300 yen per person applies from age 13.
