The 安岡港甲防波堤灯台 (An'ōkō Port Kō Defend Lighthouse) is located in Shimonoseki, Yamaguchi Prefecture, Japan.

Construction and History

The exact construction date of the 安岡港甲防波堤灯台 is unknown, but it is believed to have been built during the Meiji period (1868-1912). The lighthouse was designed in a traditional Japanese style, with a white-painted tower and a red lantern room. The structure's foundation is anchored to the sea floor using steel pilings.

Architecture and Materials

The lighthouse stands at an impressive 14 meters (46 feet) tall, with a focal height of 12.5 meters (41 feet) above sea level.

The lighthouse's primary function is to provide a beacon for mariners navigating the Kanmon Strait, which connects the Seto Inland Sea to the East China Sea. The light emits a characteristic Fl (3) W 15s pattern, with a range of approximately 12 nautical miles (22 kilometers). This signals the presence of land and helps vessels avoid potential hazards.
