It is attached to a single-story concrete equipment building. While the site is open to visitors, the tower itself is closed to the public.

Why it matters: The lighthouse illuminates the Todo Shima reef northeast of the facility, a hazard for vessels navigating the west side of Hamaonishibetsu port.
