Lighthouses of Japan: Ōsaka Area

This page includes lighthouses of the Japanese prefecture of Ōsaka, including the greater Ōsaka metropolitan area.

Ōsaka Prefecture faces west on Ōsaka Bay, the eastern end of the Seto Inland Sea (Seto Naikai), which separates Honshū from Shikoku. It is a coast crowded with port facilities. These industrialized facilities continue westward through the city of Kōbe, which is in Hyōgo Prefecture. Since port areas are typically closed to casual visitors, information on the many harbor lights of Ōsaka is rather scarce.

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 ko is a harbor. Lighthouses in Japan are operated and maintained by the Japanese Coast Guard's Maritime Safety Agency, and specifically the Ōsaka Coast Guard Office.

ARLHS numbers are from the ARLHS World List of Lights. JCG 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.
