A Natural Hot Spring Gushing from 1,500m Below Ground
Otemachi Onsen, which springs from a place where the sea used to spread out in ancient times, is a salty hot spring that contains a lot of sea water and seaweed minerals trapped deep in the ground. Soaking in this soothing hot spring that gently embraces the skin helps alleviate fatigue both in body and mind.

Leaving the outdoor hot spring from the cavernous indoor bath, you can enjoy the clipped sky of Tokyo all to yourself. The flowing clouds, the dusk sky color, and the unwearied view of the bathtub bring you serenity.
