The Seto Inland Sea, which is referred to as Japan's "Mediterranean", is a large body of water in western Japan studded with 700 islands of all sizes. Since ancient times, it has prospered as the primary transportation and trade route in western Japan, and it still retains heavy traces of old Japan. Take a leisurely yacht cruise near Hiroshima Prefecture, explore small remote islands, visit an old pirate fortress and an island of wild rabbits, and stroll through the picturesque port town of Onomichi.
