Sea Forest Waterway

On a lush artificial island, in the shadow of the huge Tokyo Gate Bridge, sits the Sea Forest Waterway -- a two-kilometre basin protected from the sea by a dam, where rowers will glide along eight competition lanes.

Built to seat 24,000, the arena's capacity will be reduced to 2,000 afterwards when it will host 30 competitions per year as well as canoeing and rowing classes.
