Shiretokomisaki lighthouse, Navigational lighthouse in Shari, Japan.

Shiretokomisaki lighthouse is a white navigation structure perched on a cliff at the northern tip of the Shiretoko Peninsula overlooking the Sea of Okhotsk. The facility includes the tower itself and supporting buildings necessary for its maritime operations.

The Coast Guard established this navigation structure in 1963 to improve vessel safety along Hokkaido's northern waters. Construction was needed because the region experiences unpredictable weather and challenging ocean currents that pose navigation hazards.

The name comes from the Ainu language and means 'land at the end of the earth', reflecting the indigenous roots of the region. Local geography and place names throughout the peninsula preserve these linguistic ties to the Ainu people who inhabited the area for centuries.

The lighthouse stands inside the special protection zone of Shiretoko National Park, where new construction is banned, so it cannot be reached on foot by visitors. Sightseeing boats from Utoro pass offshore and only allow viewing from a distance at sea. The surrounding waters lie outside mobile phone coverage.

The lighthouse stands inside the special protection zone of Shiretoko National Park, where new towers are generally banned, so the cape and its surrounding waters lie outside all mobile phone coverage. After the 2022 sightseeing boat sinking, the lighthouse area was considered a candidate site for a base station, but concern for the white-tailed eagle led to the plan being abandoned in October 2024.
