East of Kanazawa City, Yuwaku Hot Springs are located at an altitude of 400 meters, in a secluded location, at the foot of Mt. Ioh in the Hakusan range.    The atmosphere is rustic, and there are about 10 inns here. Nearby, are Lake Gyokusenko, where pure white skunk cabbage blooms in the early summer, and Yakushido (the Healing Buddha Temple).    The slightly salty spring waters contain gypsum and the water temperature is around 40 degrees Celsius. It is effective for wounds, neuralgia, and gastrointestinal disorders.   Here Takehisa Yumeji, the artist and poet, stayed secretly with his mistress, Hisano. Their favorite place for walking was said to be the grounds of Yakushido, where one of Yumeji's poems is inscribed on a monument.    The poem starts, Yuwaku naru Yamahutokoro no koharubi ni… (In the depths of the mountains called Yuwaku, during koharubi…) (*Koharubi is literally a short period of spring-like weather, similar to an Indian summer).
