We have prepared dishes with inherited techniques and dedication, utilizing seasonal ingredients from each of the four seasons. Enjoy handmade dishes featuring freshly caught seafood from the Sea of Japan and seasonal ingredients.
Iwamuro Onsen, which once thrived as an entertainment area for visitors to Yahiko Shrine, has a legend of an injured wild goose that landed here and healed its wounds with the spring water. Even today, it attracts many tourists from within and outside the prefecture. The waters of Iwamuro Onsen are known to make the skin smooth.
