HOSHINOYA Karuizawa began as a hot spring bath dug by founder Kunitsugu Hoshino in 1914, in an area that had long been known as a hot spring hotspot. Its soothing waters served as a kind of balm for bathers returning from the Kusatsu hot springs－famous for their acidity.The Hoshino hot spring is still an integral part of the resort. The restorative effects that have soothed generations of bathers can be found in the resort's Tombo-no-yu, as well as the more contemporary Meditation Bath, which emphasizes total body relaxation.

Achieving complete balance through your stay.
We offer a special program where a dietician specialist guides participants toward complete inner and outer balance through the resort's services: dining, spa treatments, hot springs, and activities. Several plans are available to accommodate length of stay and the participant's needs.
