Sarushima (猿島 Saru-shima, meaning "Monkey Island" in the Japanese language), is a small island located off Yokosuka, Kanagawa in Japan. It is the only natural island in Tokyo Bay. Sarushima was used as a battery by the Tokugawa shogunate during the Edo period, and after the Meiji Restoration in 1868, the island was developed as part of the Yokosuka Navy Yard.
