Ryugujo Spa Hotel Mikazuki to Open Major Tokyo Bay Infinity Pool

Ryugujo Spa Hotel Mikazuki has announced the opening of a significant new infinity pool, scheduled to debut on July 18, 2026. Located within the Spa Building of the resort in Kisarazu, Chiba Prefecture, the pool is designed to serve as a new landmark for the Tokyo Bay area, providing a specialized environment tailored to its coastal setting.

A Seamless Connection to the Horizon

The 25-meter infinity pool is engineered to align precisely with the water level of Tokyo Bay, creating a visual effect that merges the pool with the sea. This design allows guests to experience a sense of continuity with the horizon. The atmosphere of the facility shifts throughout the day, transitioning from the bright blue tones of daylight to a more subdued environment as the sun sets over the bay.

Views of Japan’s Largest Tidal Flats

The facility is positioned to overlook one of the largest tidal flats in Japan. This specific geography provides a landscape that changes character with the movement of the tides, offering a perspective on the Kisarazu coastline that is rare for the region. The project aims to highlight the intersection of the natural environment and the vast horizon of the bay.
