Guide

What visitors add

Outdoor bath & sauna

Sauna temperature reports vary: one reviewer measured 97 degrees C in June 2026 and called it unusually hot, while 2 others describe the sauna as mild/not too hot; one reviewer says the cold plunge reportedly uses source water. A separate paid bedrock-bath (ganbanyoku) area with multiple rooms, a cooling room, drink bar and manga lounge is praised by at least 5 distinct reviews.

Price

One reviewer (May 2026) paid 850 yen for weekend/holiday day-use bathing; 3 distinct reviews cite a weekday morning-bath + breakfast-buffet plan at 1400 yen; one reviewer cites a weekday bedrock-bath (onkatsu) set also at 1400 yen; one reviewer mentions paying 1600 yen for bath plus buffet, and another estimates just under 2000 yen for a full day including bedrock baths.

stated by 7 visitors · May 2026 – Aug 2026

Day-use visits

Opens at 7:00 am for morning bathing (one reviewer timed arrival to the 7 am opening; breakfast buffet runs 7:00-9:30 per another); baths close at 23:00 per one hotel guest who wished they stayed open later; the onkatsu cafe / bedrock-bath area does not open until 10:30, which left one morning visitor with an awkward gap.

The water

One reviewer describes the spring as weakly alkaline chloride water drawn from 1,400 m underground; another independently describes very salty, lukewarm water with a faint peaty smell; bath temperature is on the mild side (one measured just under 40 degrees C, another praises the lukewarm temperature for long soaks); one reviewer compares the after-bath feel to Ikaho onsen.

Outdoor bath & sauna

There is an open-air bath plus multiple indoor tubs and a sauna on an upper floor (about the 5th-floor level, reached by elevator): 3 reviews praise the elevated view of the surrounding countryside, but one August 2026 reviewer says a privacy screen means you actually only see sky from the rotenburo, and another visiting at night could not judge the view.

Towels, soap & lockers

Shoe and changing-room lockers require a 100-yen coin: 5 distinct reviews mention this, 2 of them clarifying the coin is returned, but reviewers still find carrying coins for every bath a nuisance; one adds the shoe locker key cannot be left at the desk.
