| Hokkaidō is the northernmost of the four main islands of Japan. It is very roughly triangular in shape, facing northeast on the Sea of Okhotsk, southeast on the Pacific Ocean, and west on the Sea of Japan. It is separated from Honshū to the south by the Tsugaru Strait and from Russian Sakhalin to the north by the La Pérouse or Sōya Strait. The entire island forms a single prefecture, which is easily the largest prefecture of Japan. This page covers lighthouses of the southern coast of Hokkaidō in Oshima subprefecture. It includes lighthouses facing the Pacific Ocean and the Tsugaru Strait. In Japanese, the word for a lighthouse is tōdai or toudai (灯台). The words saki and misaki are for capes and headlands, shima (also spelled sima or jima) is an island, wan is a bay, and kō is a harbor. Lighthouses in Japan are operated and maintained by the Japanese Coast Guard's Maritime Safety Agency. Lighthouses in Oshima subprefecture are maintained by the Hakodate Coast Guard office. ARLHS numbers are from the ARLHS World List of Lights. JP numbers are the Japanese Coast Guard's light list numbers. Admiralty numbers are from volume M of the Admiralty List of Lights & Fog Signals. U.S. NGA List numbers are from Publication 112.
