Shiobara Onsen Yumori Tanakaya

Type C rooms with an in-room onsen view bath (源泉かけ流し 温泉内風呂・次の間付客室, 5F, about 46㎡)

The sweet spot: a 12.5-tatami main room plus a 6-tatami side room, non-smoking, with a free-flowing onsen tub by the window, installed in May 2018. Official rates run from ¥24,550 per person (off-peak weekday, two sharing) to ¥36,450 in peak season, and dinner is the top 'matsu' grade, robata or kaiseki. A May 2026 guest said the room felt clean and comfortable, but an April 2026 guest warned that the in-room tubs have an overflow hole high on the side, so you may only sit half-immersed. Type D (6F, about 26㎡, one 8-tatami corner room for two adults only, no children of primary age or under) is a cheaper way to get an in-room onsen.

Type A top-floor special rooms with an open-air bath, Sōkei (蒼景) and Kakei (佳景), 7F

The inn's flagship: Sōkei is about 68㎡ plus a 16㎡ balcony, with a 12.5-tatami main room, a 6-tatami side room, a sitting room, a tea room and a stone open-air tub of free-flowing water. Guests get the private lounge (opened April 2022, with a bar). A September 2026 repeat guest compared Sōkei to a state guest room, and a February 2026 guest loved the open-air bath, though the inn admits it is chilly when it snows. Since 3 September 2026 each room has its own rate: Sōkei from ¥48,550 per person off-peak up to ¥98,050 in peak season. The Type B 'modern special room' (5F, about 58㎡, barrier-free, semi-double twins, window-side onsen bath) is the other premium choice; an August 2026 guest whose parent uses a wheelchair called it a rare find.

Type E unrenovated standard rooms (未改修 スタンダード和室, 30㎡), and anyone sensitive to smoke

The cheapest rooms (from ¥15,650 per person off-peak) are a 10-tatami room with a window-side engawa but no onsen tub, an old three-in-one unit bath with a very small toilet, a step at the entrance and smoking allowed. If you want the robata dinner in a Type E room, there is a surcharge. In April 2026 a guest in a renovated room smelled cigarette smoke drifting into the view bath through an open window. Other 2026 notes: a frosted-glass toilet that can be seen through, worn fittings, and a guest who booked a smaller room on a second visit and found it too cramped for a lazy onsen stay.
