What makes it special
Seven of Japan's ten official spring types lie scattered across a single mountain range at Niseko.
Facilities come from the register (Wikipedia, OpenStreetMap, official sites). Those marked "natural spring unconfirmed" are listed on the basis of their name only.
JR Niseko Station on the Hakodate Line is the gateway: about 2 h 15 min from Sapporo by train via Otaru, or by reserved Chuo Bus from Sapporo or Chitose. Kiranoyu is a minute's walk from the station; Goshiki and Yumoto (Yukichichibu) are about 30 minutes by taxi.
Niseko Onsenkyo is not one spring but a scatter of them around the mountains. Close to the volcano, at Goshiki and Yumoto, the water is a milky sulfur spring rich in hydrogen sulfide; Yumoto also has a brown iron bath and a mud bath. Down the slope at Konbu and at Niseko Station the water turns clear and gentle, a simple or sodium-chloride spring. It is a textbook case of the same mountain water becoming different springs depending on the rock it passes through. The tourism association counts seven of Japan's ten spring types here.

In the saddle between Mt Annupuri and Mt Iwaonupuri (Yusato, Rankoshi) A high mountain spring with one inn and a mountain hut, at the trailhead for Iwaonupuri. Its sulfurous open-air baths face the steaming volcano.
The most volcanic of all Niseko's baths.[1]
680 Yusato, Rankoshi, at the foot of Mt Chisenupuri A town-run day-use bathhouse beside Oyunuma, a steaming hot pond. Seven open-air tubs are fed by a sulfur spring and an iron spring, and the women's side has a mud bath. 900 yen.
Compare a milky sulfur bath and a brown iron bath under one roof.[2]
1 min walk from JR Niseko Station A town-run day spa using a 35–37°C simple spring; the jacuzzi runs free-flowing from the source. 800 yen.
One minute from the train, and the clear counterpart to the mountain sulfur baths.[4]
Niseko Onsenkyo is the collective name for springs scattered around the Niseko range: Goshiki, Yumoto, Higashiyama, Konbu, Annupuri, Ekimae, Konbugawa and Kogane, with Hirafu and Kutchan now often added. Because the area is wide and many are one-inn springs, the count varies depending on who is describing it. It was designated a National Recuperation Hot Spring Area on 1 November 1958.[1]
Mountain springs are tested by heavy snow. Yakushi Onsen collapsed under snow and closed in May 2014, and the two inns at Niimi Onsen were demolished in 2020. Meanwhile the towns of Rankoshi and Niseko run public day baths at Yumoto (Yukichichibu) and at the station (Kiranoyu), keeping the gateways of the spa open.[1][2][4]
From December to March Niseko fills with skiers from around the world chasing its powder snow. Each ski area on the flanks of Annupuri has its own hot spring, so after a day on the slopes you can choose between milky sulfur water and a clear simple spring — the local luxury.[3]
