Lighthouses of Japan: Eastern Honshū

This page lists lighthouses of Japan's Ibaraki and Chiba prefectures on the east coast of Honshū, within a short drive of the Tōkyō metropolitan area. Ibaraki prefecture faces east on the open Pacific Ocean. Chiba prefecture includes the Bōsō Peninsula, which projects southward separating Tōkyō and Sagami Bays from the Pacific. This region includes some densely populated urban areas, but it also includes a surprising length of wild and scenic coastline.

In Japanese, the word for a lighthouse is tōdai (or toudai). 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. On Honshū there is usually one Coast Guard Section Office in each prefecture, sometimes two.

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.
