Kasai Kaihin Park West Nagisa 葛西海浜公園 西なぎさ

Tokyos own sandy beach: a man-made island of sand off Kasai Rinkai Park, reached by a footbridge, where the city runs a summer "sea bathing" season in a roped-off zone with the Ferris wheel behind you.

About

Kasai Kaihin Park is the sea-side counterpart to Kasai Rinkai Park, made up of two artificial sand bars, West Nagisa and East Nagisa, in the mouth of the Arakawa and Old Edo rivers. The whole area is a Ramsar-listed wetland, the first in Tokyo, and East Nagisa is closed to people as a bird refuge. West Nagisa is the public one: cross the Nagisa Bridge from the Ferris wheel and you step onto a wide beach of real sand with views of Tokyo Disney Resorts hotels across the water. Since the late 2010s the metropolitan government has opened a supervised "sea bathing" zone here each summer (roughly late July to the end of August), with lifeguards and a fixed area. Outside that window it is a place for paddling, shell spotting, kite surfing watching and sunsets. Spring tides draw families looking for crabs and small fish in the shallows.

Highlights

• Real sand beach inside Tokyos 23 wards, reached by a footbridge
• Summer supervised swimming zone (about late July to end of August)
• Ramsar-listed tidal flats with herons, cormorants and wintering ducks
• Views of the Diamond and Flower Ferris wheel and the Tokyo Disney Resort skyline
• Wide, flat sand great for kids, kites and sunset walks

Tips

• Swimming is only allowed in the marked zone during the official summer period and set hours; check the Tokyo Port Bureau notice each June.
• There are toilets and showers near the beach in summer, but no beach huts: bring water and shade.
• Combine with Tokyo Sea Life Park (the aquarium) in Kasai Rinkai Park, a 10 minute walk back.
• East Nagisa is off limits: stay on West Nagisa and do not enter the reed beds.
