About Ashika Shima Lighthouse
Also known as: Ashika Shima (Sea Lion Island)
Ashika Shima lighthouse, operational since 1916, stands on a dangerous rock approximately 1.5 kilometers southeast of Kurihama harbor. This cylindrical concrete tower, built in 1916, measures 14 meters in height and emits a white flash every 3 seconds from a focal height of 16 meters. Its construction material is concrete and its exterior is painted black with a white lantern. The lighthouse guides vessels with a geographic range of 12.2 nautical miles. It is located near Yokosuka in the Kanagawa Prefecture of Japan.
Why it matters: This lighthouse warns vessels of a hazardous rock formation, which is particularly important for ships navigating into or out of Kurihama harbor. Its distinctive black tower with a white lantern also serves as a landmark for local mariners.
