Outline of Kasai Marine Park


Kasai Marine Park consists of two beaches, one on the east and the other on the west, and water area. (The East beach is an environmental conservation zone.) The area is connected to Kasai Rinkai Park on land with the Nagisa Bridge, which is designed to evoke the image of the mast of a yacht.
Admire the waters of Tokyo Bay beyond the vast sandy beaches from the east and west beaches.

At the west beach, visitors can enjoy recreational activities including sport kite flying and barbequing.
During clam digging season, the beach becomes extremely crowded with people.

In general, visitors are prohibited from entering the east beach, because it is an important wild bird sanctuary.
