Kasai Rinkai Park is a large, green park on the edge of Tokyo Bay, with the mouth of the Ara River to the west and a branch of the Edo River exiting to the east.

Within the park is a huge number of recreational and sightseeing facilities, including a giant ferris wheel, an aquarium, sports fields, a BBQ area (bookings here), and even the whitewater canoeing course for the Tokyo Olympics.

Easiest access is via Kasai-rinkai Park Station on the Keiyo Line. There is also a Suijo Bus (ferry/cruise) service to the park from Ryogoku (¥2,400) and Odaiba (¥1,200).
