⑥ Sea Forest Waterway
Covered with lush greenery, the Sea Forest Waterway is also known as the boating and canoeing venue for the Tokyo 2020 Olympic Games. Take a rest at the aid station while enjoying the kind of magnificent view that only Tokyo Bay can offer.

⑦ Tokyo Gate Bridge
This bridge is also called the Dinosaur Bridge because it looks like two dinosaurs are facing each other. Tokyo Gate Bridge offers a wonderful view of Tokyo Skytree and Tokyo Disneyland etc. If you are lucky you may be able to see a plane fly right above you as it is close to Haneda Airport.
