Mugiyama Floating Bridge (Lake Okutama) 麦山浮橋(奥多摩湖)

A wobbly bridge of plastic floats that lets you walk right across the middle of Lake Okutama, Tokyo's largest reservoir. The forested mountains are reflected in the water on both sides, and locals nicknamed it the "drum-can bridge" after its original oil-drum floats.

About

Lake Okutama was created in 1957 when the Ogochi Dam flooded a mountain valley to supply Tokyo with water. Two floating bridges were laid across its arms so residents of the drowned villages could reach the other side. The Mugiyama floating bridge, about 200 m long, was originally carried on oil drums, which is why locals still call it the drum-can bridge. Today it floats on plastic pontoons, and it gently sways as you walk across with the cool water just centimetres below. It is closed when the water level is low or the weather is bad. Mountains rise steeply on all sides, maples glow in November, and there are rarely more than a few people. Combine it with the dam's viewpoint and the Okutama Water and Green Hall nearby.
