Place name of Tsushima has the special characteristics, which is different from that of near Iki Isl. and Goto Isl. Dan or Danyama is the name of the mountain. The plain on the top of a mountain is Yamandan. The saddle of a mountain is Togendan. The field in the mountain is danbaru or danbari. The mountain range is sone, keta and kuma. Sone means the rock pile in the sea at Iki Isl. Kuma means in usual the heart of a mountain or the small basin along the river, but it means the top of a mountain at Tsushima Koba is the place name of the land under cultivation relating to the burning cultivation field. The valley is called sale, Kubo udou wada and wami are also used. At Iki Isl. wada means the small settlement. The field is baru or bari.
