Sarushima, Desert island in Yokosuka, Japan
Located in Tokyo Bay, Sarushima extends over 0.055 square kilometers with a coastline of 1.6 kilometers and reaches an elevation of 39.3 meters.
The Tokugawa shogunate established military batteries on the island during the Edo period, later developed as part of Yokosuka Navy Yard after 1868.
The island contains red brick barracks, powder magazines, and stone walls that demonstrate the traditional Japanese coastal defense architecture.
Visitors can reach the island by regular ferry service from Yokosuka Chuo Station, with operating hours from 9:30 AM to 5:00 PM during summer months.
Sarushima stands as the only natural island in Tokyo Bay, featuring a network of brick tunnels and abandoned military structures throughout its territory.
