Nozawa Onsen Kawaichiya Ryokan

野沢温泉 河一屋旅館

A renovated Nozawa inn with two different springs under one roof, including the prized Shin-yu, piped free-flowing into its outdoor bath and newer in-room baths, plus a two-wagyu steak dinner and near-perfect service scores. The catches: thin walls, a maze of stairs and corridors, and very hot water

Ryokan Sakaya

野沢温泉 旅館さかや

The big inn beside Nozawa's Ōyu bathhouse, with its own sulphur spring rising in the garden and running unwatered through a shrine-carpenter bathhouse of hot, warm and lie-down tubs. The catches: plain cheaper rooms, weak summer air-conditioning and strict winter booking rules

Kasuitei Ooya

花水庭おおや

A century-old, family-friendly lakeside inn with generous kaiseki dinners (often served in your room) and rooftop baths over Lake Kawaguchi — but Mt Fuji is behind the building, the in-room open-air baths aren't onsen, and the building shows its age

Shuhokaku Kogetsu

秀峰閣 湖月

A 43-room lakeside inn where every room faces Mt Fuji across Lake Kawaguchi, with kaiseki served in your room and free drinks on a foot-bath terrace — but the baths are recirculated, standard rooms have only a shower, and dinner moves to a dining hall from April 2027

Fuji-Kawaguchiko Onsen Konanso

富士河口湖温泉郷 湖南荘

A big, polished lakeside inn that still serves kaiseki dinner in your room, with Mt Fuji from the rooftop foot bath — but it stands on the town shore, so 40 of its 50 rooms face the lake rather than Fuji, and the heated spring water has little character

Kozantei Ubuya

湖山亭うぶや

Un gran ryokan a orillas del lago con la celebración como tema, donde todas las habitaciones miran al monte Fuji al otro lado del lago Kawaguchi — pero los baños al aire libre de las habitaciones no son onsen, la cena es ahora un bufé o shabu-shabu y el Fuji suele esconderse en verano
