Lighthouses of Japan: Eastern Shizuoka

This page lists lighthouses of the Japanese prefecture of Shizuoka, which faces south on the Pacific Ocean southwest of Tokyo. Shizuoka Prefecture includes some of Japan's best known and most scenic coastlines; the arrowhead-shaped Izu Peninsula shelters Suruga Bay, with the famous cone of Mount Fuji on the northern horizon.

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. On Honshū there is usually one Coast Guard Section Office in each prefecture, sometimes two. Shizuoka has two Coast Guard offices: at Shimoda on the Izu Peninsula and at Shimizu on Suruga Bay.This page describes the lighthouses of the Shimoda Coast Guard District, including most of the Izu Peninsula.

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.
