The Sea Forest Waterway (Japanese: 海の森水上競技場, Hepburn: Umi no mori suijō kyōgi-jō) is a regatta venue for rowing and canoeing, situated in Kōtō and Ōta, Tokyo Bay, in Japan.

Tokyo Gate Bridge provides the backdrop to the rowing course looking from start to the finish line.

[1] There is no public transport access to the venue, with the nearest rapid transit station—Tokyo Teleport Station that is located on the Rinkai Line—is about 7 kilometres (4.3 mi) away.

[5] The course is separated from Tokyo Bay by dams at each end of the course, which hold the water at a consistent depth of about 6 metres (20 ft).

[1][7] Haneda Airport is just to the south from here, with planes flying low over Sea Forest Waterway.
