Yunohama Roten Onsen 湯の浜露天風呂

Mamashita, Honson, Niijima Village, Tokyo

Gaze out at the sea from the warmth of an open-air island onsen

Just five minutes on foot from Niijima Port, Yunohama Roten Onsen is an open-air hot-spring bath that offers a stunning panorama of the ocean, enhanced by Greek-inspired archetectural motifs. Best of all, these baths are free to enter.

Six baths of various sizes offer plenty of variety, and they're spacious enough to hold up to approximately 80 people. One of the best times to enjoy a soak at Yunohama Roten Onsen is as the sun sinks into the sea. The view of the sky on a starry night is a close second. Remember to bring a swimsuit for the mixed bath.
