Kimitsu Onsen is located in Kimitsu City, Chiba Prefecture, in the Futtsu-Kimitsu highland interior of the Boso Peninsula where the Otaki waterfall — one of Japan's one hundred famous waterfalls, plunging 80 meters through a forested gorge — creates a major natural attraction in this scenic corner of Chiba's green interior. The siliceous thermal waters here serve a city whose diverse character encompasses Tokyo Bay coastal industrial development, the dramatic inland highland forests of the Boso's central ridge, and the natural beauty of the Otaki waterfall gorge that attracts both hikers and sightseers from the Kanto region. Bathing at Kimitsu Onsen after visiting the spectacular Otaki waterfall provides a complete southern Boso natural heritage experience, combining the dramatic beauty of one of Japan's finest waterfalls with the restorative comfort of therapeutic siliceous mineral spring bathing in Chiba's scenic interior highlands.
