Today we visited Miyajima (Shrine Island), an island famous for the O-Torii gate seemingly surrounded by water.
Gunkanjima (Battleship Island) was originally called Hashima with a seabed coalmine. After the mine was closed, the island fell into ruin.
Dejima was used to quarantine foreign traders (Portuguese, then Dutch) during the Edo period of the Tokugawa Shogunate.
