Hachikokuyama is a ridge and park in Higashimurayama, Tokyo along its border with Tokorozawa, Saitama. Its name translates literally into English as "Eight Country Mountain" since, in the past, one could view the eight surrounding provinces surrounding Musashi Province from its top including Suruga, Kai, Izu, Sagami, Hitachi, Kozuke, Shimotsuke, and Shinano. The park was opened in 1990. In Japanese it is designated as a ryokuchi instead of a park.
