Shikoku

Shikoku ("four provinces") is the smallest (225 km or 139.8 mi long and between 50 and 150 km or 31.1 and 93.2 mi wide) and least populous (4,141,955 as of 2005) of the four main islands of Japan, located south of Honshū and east of the island of Kyūshū. Its ancient names include Iyo-no-futana-shima (伊予之二名島), Iyo-shima (伊予島), and Futana-shima (二名島). The current name refers to the four former provinces that made up the island: Awa, Tosa, Sanuki, and Iyo.
