Yagen Valley

What to know

Much of the Shimokita Peninsula is sparsely inhabited due to its remote, rugged terrain. The Yagen Valley (Yagen Keiryū) in the middle of the peninsula is no exception—a quiet, isolated area offering hiking, hot springs, and little else.

Two of the Yagen Valley's hot spring baths are named after the kappa, a mythical creature that lives in ponds, rivers, and lakes and tends to be somewhat devious; its favorite snack is small children. However, kappa are not really evil, just a bit mischievous. They can be persuaded to exchange a meal of children for a cucumber, another favored snack. In fact, the Japanese word for sushi rolls filled with cucumber is kappamaki due to the kappa's love of the vegetable.

The two kappa baths are located in the Oku-Yagen area ("Inner Yagen Valley") in the back of the valley, facing the river and offering pleasant views. The Meoto Kappa no Yu offers open-air, gender-segregated baths and comes with changing room facilities and a small restaurant. The Kappa no Yu is equipped with a roof and changing room facilities. Formerly mixed, the pool now alternates between women-only and men-only every two hours.

Hiking is also possible in the Yagen Valley. Easy paths take hikers along the riverside and through some of the old-growth forest. There are only a few lodging options in the valley, including small ryokan and minshuku (small inns).

There is no public transportation to the Yagen Valley; the only way to access the valley is by rental car.
