Spa & Esthetic


Refill your body in hot water while feeling the breath of nature.

The history of Kagetsu began in 1961 with the opening of Isawa Onsen,
when a hot spring suddenly sprang out in the middle of a vineyard.
Admire the scenery of the garden that changes from season to season through rising steam.
Overflowing green, falls that play hide-and-seek in a rich air, high-standing rocks,
and streams babbling at your feet.
Entrust your body at ease in the spacious bath and enjoy a time to blend together with nature.


Surrounded by mountains, such as Mount Fuji, the Southern Alps and the Daibosatsu mountain range, Isawa is famous as a beautiful hot spring town.
Amidst this, Kagetsu- the monument stone inn, is well-known as an old-style inn located in the middle of Isawa Onsen.

The heartwarming scent of steam; The Big Bath, full of rural charm of each season.
Please enjoy a fulfilling time bathing into our famous hot spring bath, to relax both your body and your spirit embraced by giant peculiar stones.
