Mishima Skywalk is a pedestrian bridge officially known as the Hakone Seiroku Mishima Suspension Bridge that spans a valley on the southwestern rim of the Mount Hakone caldera in Mishima, Shizuoka, Japan. The primary function of the bridge is to provide visitors with panoramic views of Mount Fuji and Suruga Bay. Measuring 400 metres (1,300 ft), it is the longest suspension footbridge in Japan, surpassing the 390 metres (1,280 ft) long Kokonoe Yume Suspension Bridge in Kokonoe, Ōita upon its completion in 2015.
