Yamato no Yu Bathhouse

Yamato no Yu (大和の湯) is a serene and contemporary bathhouse located just south of Boso no Mura and a short drive from Narita Airport — making it an ideal stop for travelers with a few hours to spare. The facility offers a variety of gender-separated indoor and open-air baths, as well as a dry sauna, all set against a peaceful countryside backdrop. The baths use mineral-rich geothermal water that naturally emerges at just 19°C, but is heated to a soothing 41°C for comfort. Due to its low natural temperature, the water is classified as a reisen (cold spring) rather than a traditional onsen, though it provides similar therapeutic benefits.

In addition to its bathing areas, Yamato no Yu offers a full range of relaxing amenities. Visitors can reserve one of three elegant private baths on the day of their visit—ideal for couples or those seeking extra privacy. Inside, guests can unwind in a tranquil lounge, enjoy a refined Japanese restaurant or sushi bar, and make use of the gym and spa facilities. While children under six are not permitted in order to preserve the calm atmosphere, guests with tattoos are welcome—making it an inclusive and inviting destination for international travelers looking for a modern yet authentic Japanese bathing experience.
