A cylindrical concrete tower, 10 meters in height, was constructed and first lit in 1977. Attached to the tower is a single-story concrete equipment room. The focal height of the light is 54 meters above sea level, and it emits an occulting white light every 5 seconds. This lighthouse is situated on a promontory on Kami-Koshikijima, about 3 kilometers south of Ite Saki. The geographic range of the light extends to 19.3 nautical miles. The nearest port is Eishi, located 3.3 kilometers away.

Why it matters: The Sato Saki light assists vessels in identifying the promontory, which is critical for safe passage along the coast of Kami-Koshikijima and for local fishing fleets.
