Lighthouses of Japan: Imabari Area (Northern Ehime)

Smallest of the Japanese main islands, Shikoku is divided into four prefectures. This page includes lighthouses of northern Ehime Prefecture, a coastline facing north on the Inland Sea. This is a scenic and well populated coast with numerous harbors.

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, andis 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. Lighthouses in northern Ehime are managed by the office at Imabari, except some of the lights of Kamijima Town which are managed by the Onomichi office in Hiroshima prefecture.

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.
