Naruko Onsen

Taki-no-Yu, Naruko

A communal bath with over a thousand years of history as the shrine's sacred spring. Milky acidic sulfur water pours like a waterfall from log flumes into cypress tubs. ¥300; bring your own soap.

Naruko Waseda Sajiki-yu

A communal bath using a spring that Waseda University students struck during fieldwork in 1948. Architect Osamu Ishiyama's yellow avant-garde building is unmistakable; descend the stepped 'sajiki' gallery to the bathroom. The modern counterpart to Taki-no-yu.
