Kasai Marine Park 葛西海浜公園
Sea swimming in Tokyo lasts six weeks: from 19 July to 30 August, free, 10:00–16:00
The park opened on 1 June 1989 on a stretch of bay reclaimed from the sea, with two artificial beaches (なぎさ, nagisa): the western one, about 830 metres, open to the public, and the eastern one, about 770 metres, a bird sanctuary closed to visitors. It is connected to the nearby Kasai Rinkai Park by the Nagisabashi footbridge.
