The gateway to Izu. The only cloudy hot spring in Numazu.

Our establishment is an Onsen Ryokan nestled at the foot of Mount Zōsan, the gateway to Izu. "Tsuki no Yu Onsen," the only cloudy hot spring in Numazu, is a natural ion Onsen known for its skin-beautifying properties. It was named "Tsuki no Yu Onsen" after being discovered in the year of the Apollo moon landing and has been cherished by many ever since. From Numazu Port, where approximately 1,000 types of seafood are landed daily, our chefs prepare the freshest seafood caught that very day. After enjoying your delightful journey, relax and rejuvenate in the natural Onsen and savor the fresh seafood delicacies from Suruga Bay.
