Kii Hinomisaki Lighthouse, Lighthouse on Cape Hinomisaki in Hidaka, Wakayama Prefecture, Japan.

The Kii Hinomisaki Lighthouse is a white, tower-shaped structure at the tip of Hinomisaki Cape in Hidaka, Wakayama Prefecture. The current tower is the third generation, first lit on 23 March 2017 after being moved about 120 meters west from its predecessor's site due to landslide risk. It stands within the Nanki Kumano Geopark and faces the Kii Channel.

The first Kii Hinomisaki Lighthouse was lit on 25 January 1895 at Cape Hinomisaki, a white circular iron tower with a second-order flashing white light visible for 23 nautical miles. It was destroyed in 1945 by US carrier aircraft fire and a small bomb that set the fuel store ablaze. A second lighthouse was completed in 1951, and the current third-generation tower was first lit on 23 March 2017, about 120 m west of the previous site, after ground cracks raised landslide concerns.

The lighthouse serves as a landmark for coastal communities and represents the ongoing relationship between fishing traditions and maritime navigation in this region. Its presence connects the daily life of people living nearby to the sea's rhythm and the vessels that pass through these waters.

The lighthouse is accessible by public transportation connecting from train stations in the Hidaka area, though the final approach involves walking along the coastline. Visitors should expect exposed conditions and bring appropriate clothing for wind and sea spray.

The lighthouse employs distinctive light signals that allow vessels to identify their specific location, particularly valuable during foggy or stormy conditions that commonly affect this coast. This signaling system sets it apart from other navigation aids in neighboring waters.
