Biruwa, in forest on the southeast side of Lake Kussharo Private sauna and hot-spring house, one group at a time ★★☆☆☆

Does Kussharoko Sauna Club allow tattoos? In a private bath

Private bath only

A cedar sauna, a spring called the Woodpecker’s Bath and a 170 cm miso barrel of Mashu groundwater stand together in the forest above Kussharo, and the operator only ever sells them to one party at a time.

There is no tattoo rule here because there is nobody to meet. The operator sells the building one party at a time: the sauna and the baths go out in two-hour day slots at 19,800 yen for up to six people, and overnight guests get the whole place from 16:00 to 09:00 the next morning, with all three bedrooms priced as a single unit whether one person comes or nine. The bathing set is an indoor hot-spring bath, an outdoor hot-spring bath, a wood-fired sauna with spring water poured on the stones, and a 170 cm miso barrel of Mashu groundwater as the cold tub.

What happens when you arrive

Skip the shared baths and reserve the private one the way this page describes. Once the door is closed, the bath is yours.

How we know

Confirmed from official site — bath structure, not a tattoo policy (the operator’s own SAUNA and HOTEL pages)

Best for: A group that wants a hot spring, a wood-fired sauna and a barrel of cold lake-country water with the gate shut behind them

The spring is 屈斜路温泉, source name アカゲラの湯, given as 59.8°C and ナトリウム-炭酸水素塩温泉 (低張性弱アルカリ性高温泉). Day slots are 10:00–12:00 and 13:00–15:00 only; overnight guests have the sauna and baths 16:00–09:00. Bath towels and the water server are free; swimsuits, ponchos and sauna hats rent. The barrel is a 170 cm Saga miso cask filled with Mashu groundwater. The sauna room is western red cedar with a double-door airlock. There are three bedrooms sleeping nine in total and the single toilet is unisex.
