Hoshi Ryokan is a traditional Japanese inn located in the Awazu Onsen area of Komatsu in Ishikawa Prefecture. The historic inn was founded in the year 718, making it the third oldest in Japan and the world. This hotel is not only old, its origins are divine. According to legend, the god of Mount Hakusan visited a Buddhist priest, telling him to uncover an underground hot spring in a nearby village. The hot spring was found, and the priest requested that his disciple, Garyo Saskiri, build and run a spa on the site. His family, known as Hoshi, has owned and run the hotel in Komatsu ever since for 46 generations.

Guests are warmly welcomed with a traditional Japanese tea ceremony, which is part of the charm. Relaxation is key here, with guests able to stroll in one of the traditional Japanese landscape gardens, soak in either the indoor or outdoor hot springs, and slip into a yukata (light summer kimono) for even more comfort.
