Lighthouses of Japan: Kagawa

Smallest of the Japanese main islands, Shikoku is divided into four prefectures. This page includes lighthouses of Kagawa Prefecture, at the northeastern end of the island. Facing north on the Seto Inland Sea, Kagawa has many ports both large and small between its prominent and scenic headlands. Takamatsu, the capital of the prefecture, is also the largest port.

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 is a harbor. Lighthouses in Japan are operated and maintained by the Japanese Coast Guard's Maritime Safety Agency. There is at least one Coast Guard Section Office in each prefecture, often two or more. Kagama has one office, at Takamatsu.

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.
