Gero Onsen Sasara

下呂温泉 紗々羅

Gero's self-styled 'art inn' on the hill: antique-crammed lobbies, 20 of 44 rooms with their own open-air onsen, in-room Hida-beef dinners and a top-floor bath over the town lights — but breakfast underwhelms, the Moriyama wing is a long walk from the baths, and renovation noise runs until the end of 2026

Gero Onsen Bosenkan

下呂温泉 望川館

A friendly, family-minded Gero inn founded in 1818, with a 1,100-tsubo garden, a big riverside open-air bath, Hida beef hoba-miso dinners in private rooms and trains rumbling over the bridge outside — but the building is old, the baths are partly recirculated and down a steep flight of stairs

Gero Onsen Ogawaya

下呂温泉 小川屋

Gero's big bath-hopping inn: a 100-tatami 'tatami bath', five shared baths, nine private ones and a menu of Hida-beef dinners in the middle of town — but it's a 120-room maze, the private baths cost extra, and 2026 reviews complain of queues and uneven service

Gero Onsen Suimeikan

下呂温泉 水明館

Gero's grand ryokan since 1932: four wings, three big baths of silky alkaline water and Hida beef everywhere — choose the Rinsenkaku wing for onsen in your room, and expect crowds and tired rooms elsewhere

Yuyado Toki no Niwa

湯宿 季の庭

A tatami-floored Kusatsu inn where all 64 rooms have an open-air onsen bath, plus 23 tubs shared with a sister inn — but the room baths are filled on demand rather than free-flowing, it's a 15–20-minute walk from the Yubatake, and 2025–2026 guests report an ageing building

Kanamean Nishitomiya

要庵西富家

An eight-room sukiya inn in the heart of Kyoto where dinner is the point — a Michelin-starred kaiseki kitchen you tour before eating, hinoki baths in every room, and two MICHELIN Keys since 2026 — but it isn't an onsen, the water runs very hot, and old floors carry sound
