About Shiriuchi Town Lighthouse Lighthouse

The Shiriuchi Town Lighthouse, built in 1957, is a cylindrical concrete tower standing 8 meters tall. It emits a single white flash every 10 seconds, visible for over 24 nautical miles. The lighthouse is situated on a high promontory on the northwest side of the Tsugaru Strait, approximately 8 kilometers south of Shuriuchi. Its structure includes a lantern and gallery atop the white tower, which rises directly from a small, one-story keeper's house. The focal height of the light is 96 meters above sea level.

Why it matters: This lighthouse serves as a critical navigational aid for vessels transiting the Tsugaru Strait, a major shipping route. Its light warns mariners of the promontory on which it stands, helping to prevent groundings in this challenging area.
