Yōrō Keikoku Okukiyosumi Prefectural Natural Park is a Prefectural Natural Park in southern Chiba Prefecture, Japan. First designated for protection in 1935, the park's central features are the Yōrō Valley and Kiyosumi Mountains (清澄山地). The park spans the municipalities of Ichihara, Kamogawa, Kimitsu, and Ōtaki.
Insider tip — Yoro-keikoku Onsen is nestled in the scenic Yoro Valley of the Boso Peninsula in Chiba Prefecture, just 60 km east of Tokyo. The gentle gorge carved by the Yoro River provides a surprisingly rural escape from the metropolis, with classic wooden ryokan lining the valley floor. Autumn foliage along the canyon walls makes this a popular weekend retreat for Tokyoites.
