Janoyu Onsen Takaraso: Day-Use Hot Spring Baths & Prices

In the Kazuma hamlet of Hinohara, at an elevation of around six hundred meters, a sturdy thatched-roof inn stands quietly among the mountains. The kabuto-zukuri building, with more than three centuries of history, is a registered tangible cultural property and is known as one of the few remaining hidden hot spring inns in Tokyo. Its name is said to come from a legend of an injured snake that healed itself in the spring.

Highlights

• A thatched kabuto-zukuri building carrying over three hundred years of history
• The rustic atmosphere of a hidden spring set in mountain silence
• A calm soak that day visitors can also enjoy
• The timeless scenery spread across the mountain village of Kazuma

Enjoying the Seasons

Spring buds, deep summer green, autumn foliage, and winter snow each frame the thatched inn in a picture-worthy way. The sight of the snow-capped thatched roof in particular has the charm of stepping into an old folk tale, leaving a deep impression on every visitor.

Access and Basic Information

• Location: 2465 Kazuma, Hinohara, Nishitama District, Tokyo
• Access: about 65 minutes by Nishi-Tokyo Bus toward Kazuma from Musashi-Itsukaichi Station on the JR Itsukaichi Line, then a short walk from the Kazuma bus stop near the terminus
• By car: parking is available (about 10 spaces)
• Day-use bathing: generally received from around 10:00 to 18:00 (after 18:00 for overnight guests only), roughly 1,000 yen for adults
• Spring quality: an alkaline sodium chloride spring, colorless, clear, and gentle
• A historic, culturally designated building offering both overnight lodging and day-use bathing

Practical Travel Notes

• Recommended seasons: early summer greenery and late autumn foliage are especially beautiful, and the snowy winter has a rustic charm all its own.
• Time needed: it lies deep in the mountains, over an hour by bus from Musashi-Itsukaichi Station, so even a day trip becomes a half-day to full-day outing.
• Avoiding crowds: day-use bathing days and hours can be limited, so confirming in advance by phone is the surest approach.
• Real spots nearby: Hinohara Onsen Center Kazuma-no-Yu, the Tomin-no-Mori forest park with a view of Mitou Great Falls, and Kuzuryu Falls are all within driving range.
• Budget sense: day-use bathing is around 1,000 yen for adults, and the round-trip bus fare adds up, so allow room in both time and cost.

A Quick Tip

Day-use bathing hours and days can be limited, so it is reassuring to check before you go. Buses are infrequent, so look up your return time in advance as well. Because of the deep mountain setting, warm clothing and comfortable shoes will make your visit more pleasant.
