casual Ryokan/Inn
Tatsumikan / Gunma Minakami・Tsukiyono・Sarugakyo・Hoshi 1


It's a tranquil onsen hotel situated by the Tonegawa river bank, which "Kiyoshi Yamashita, the Japanese artist called the Naked General" was besotted with.

The famed 'charcoal grilled mountain cuisine' attracts many repeat guests, and the hot spring waters have been chosen as one of the three best hot springs for beautiful skin and are also known as 'cosmetic waters'. 

The two private Japanese cypress baths, based on the themes of 'Tranquility'  and 'Movement', are also popular with our guests.

The magnificent Tanigawa Peak, the sound of the river, delicious cuisine and beautifying spring waters. 
Please experience the restrained hospitality that only this hotel can offer.

Kamimoku Onsen is a natural hot spring which has both melted waters from the snow of Tanigawa Peak and waters from the Tone River, heated for approximately 17 years underground before welling up from the ground. 
The special quality of the hot spring waters, which have been selected as one of the 'three best hot springs for beautiful skin', is that it is a 'hot spring rich in sodium sulfate (sodium / calcium-sulfate / chloride hot spring)'. They are also called 'Kesho no Yu' and 'Shiage no Yu' and they are known for being effective for its quality water that beautifies the skin, as well as keeping it moist and warm.
