Lighthouses of Japan: Iwate

This page lists lighthouses of Iwate Prefecture, near the northeastern corner of Honshū, Japan's largest island. This coast, called the Rikuchū Coast (Rikuchū Kaigan), is mostly rugged and spectacular--and dangerous to navigation. For 180 km (115 mi) south of Kuji, a narrow strip of land along the coast has been preserved as the Rikuchū Kaigan National Park. Most of these lighthouses are located in the park.

This coast was devastated by the great earthquake and tsunami of 2011 March 11. Most of the lighthouses are high enough above the sea to escape the tsunami; most were damaged by the earthquake but have been returned to service. Harbor lights, however, were mostly overturned or destroyed by the tsunami, and repairs to harbor facilities will take more time.

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 kō 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. That is the case in this region, with section offices at Kamaishi in Iwate, Miyagi, and Fukushima.

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.
