Natural hot spring baths and irori cuisine for a special time
Yamakawa ZENZO is a hidden retreat for adults where you can enjoy natural Onsen with water directly sourced from Yamakawa Onsen and traditional irori-style cuisine. Each guest room features a private open-air bath, allowing you to relax while taking in the surrounding nature. Additionally, we offer irori-grilled dishes prepared over charcoal right in front of you, paired with carefully selected beverages. The large communal bath is designed with landscaping that evokes the presence of massive rocks and mountains, creating a rustic and wild atmosphere. Savor the local ingredients of Kumamoto, the land of fire, grilled over the irori, and enjoy a truly special experience.
Both the Onsen and the food were excellent, and we were very satisfied.The irori-style cuisine was especially outstanding, and together with the atmosphere, it made for a truly luxurious time.The Onsen was also very relaxing, allowing us to unwind and forget about everyday life.Overall, it was very comfortable, and we felt completely refreshed.A wonderful place that we would definitely like to visit again.
