Experience an Unbelievably Relaxing Vacation in the Hot Springs of Karuizawa's Ryokan

Since then, the area has evolved into a popular summer vacation spot, initially by foreigners, then later by locals.

The result has been the establishment of a globally renowned resort area with fancy restaurants, fashionable shopping outlets, and some stellar hot springs.
