About To Shima Lighthouse
Also known as: To Shima (Toshima)
Constructed in 1982, the To Shima Lighthouse stands on a steep slope at the northern end of the island, overlooking the town. This cylindrical concrete tower, painted white, reaches a height of 13 meters. It emits a white flash every 6 seconds from a focal height of 66 meters, with a geographic range of 20.9 nautical miles. The lighthouse is attached to a single-story equipment building, and the site is open to visitors, though the tower itself remains closed. Its location provides panoramic views of the sea and the settlement below.
Why it matters: This lighthouse serves as a key navigational reference point, guiding vessels along the coast and assisting local fishing boats.
