Hidaka Saiboku no Yu: Hot Spring Guide & Visitor Access

Attached to the popular Saiboku complex surrounded by the rich greenery of Hidaka, the natural hot spring Kachofugetsu is an appealing bath where you can enjoy good food and a warm soak all at once. After soaking slowly in the abundant water rising from deep underground, you can taste the signature cuisine on the grounds, fully savoring a whole day. It is a perfect place for outings with family or a group.

Highlights

Beyond the comfort of the hot spring, the whole verdant grounds are a highlight. In the open-air bath you can enjoy the water in the open air surrounded by trees, and there is also a highly carbonated bath that warms you to the core. The natural spring boasts an abundant flow, and its water quality is praised as fine even by a hot-spring therapy physician. On the same grounds are facilities for dining and shopping, so dropping by after a bath lets you enjoy the whole day.

Enjoying the Seasons

Fresh green in spring, cool shade in summer, foliage in autumn, and clear air in winter, you can feel the change of seasons unique to a setting surrounded by greenery. In the leisure season it grows lively with families, and many visitors come to enjoy the day together with a bath. The signature sausages and ham unique to Saiboku are popular year round.

Access and Basic Information

The address is 546 Shimo-oyasawa, Hidaka City, Saitama. Access by car is convenient, with a large parking lot fully provided. Opening hours are 10:00 to 22:00 (last reception 21:00). Day bathing costs roughly the lower one-thousand-yen range for adults on weekdays, a little more on weekends and holidays, with a child rate of a few hundred yen for ages three through elementary school. There are occasional closed days, so checking the official website before visiting is reassuring.

Practical Travel Notes

Visiting together with dining and shopping lets you spend the day more fully. Combining bathing, a meal, and shopping on the grounds can fill about half a day, so set out with time to spare. On site are a meat shop, restaurants, and a park area, so even families with children can stay entertained. Budget roughly a few thousand yen per person once you add a meal and souvenirs to the bathing fee. Holidays in the leisure season get crowded, so aiming for just after opening or the late afternoon is a good idea for a slow soak.

A Quick Tip

Enjoying the day by moving between the highly carbonated bath and the open-air bath and pairing it with the signature cuisine is the way to make the most of Saiboku. The leisure season gets crowded, so if you want to enjoy the water slowly, visiting at an off-peak time is recommended.
