'Grand Bleu' Outdoor Pool

'Grand Bleu' is a pool facility themed after a Mediterranean port, where you can feel the sparkling sea and sky, refreshing breeze, and blessings of the ocean. The indoor pool, with its marine blue walls adorned with gracefully swimming sea turtles and tropical fish, uses heated water and is available year-round. Additionally, guests can enjoy the summer-only outdoor pool and the temporarily lit-up night pool.

The outdoor pool, where the sea breeze from Tokyo Bay is exhilarating, has a shallow area of 62cm, allowing small children to safely enjoy playing in the water.

Rental of floats and other play equipment is also available (for a fee).

From Saturday, July 18, to Monday, August 31, food, soft drinks, and non-alcoholic cocktails will be served from the adjacent counter.
