The lighthouse marks the northern boundary of the Uraga Channel, a high-traffic waterway connecting the Pacific Ocean to Tokyo Bay.
On clear days, the silhouette of Mount Fuji is visible across the water from the lighthouse grounds.
The lighthouse is a featured location in the Japanese anime 'Love Live! Sunshine!!', leading to a rise in pop-culture tourism.
The name 'Sunosaki' literally translates to 'Cape of the Sand' due to the geological composition of the promontory.
The lighthouse operates an automated rotating beacon that flashes white light at specific intervals for nocturnal identification.
Sunosaki Lighthouse, established in 1919, serves as a maritime beacon located at the southern tip of the Boso Peninsula in Tateyama, Chiba. The structure marks the eastern entrance to Tokyo Bay, functioning as a vital navigational aid for ships entering the capital region. The lighthouse was reconstructed in 1993, maintaining its historical significance while updating its illumination technology. It sits atop a cliff overlooking the Uraga Channel, offering a direct view across the sea toward the Miura Peninsula. The site is characterized by its white concrete tower design, which contrasts with the surrounding coastal topography. It remains an active navigational facility operated by the Japan Coast Guard.

Do not attempt to climb or enter the tower, as it is a restricted facility for staff only.
The lighthouse grounds are accessible year-round, though the tower itself is permanently closed to public entry.
The facility is an active maritime installation; maintain a quiet demeanor and stay within marked visitor boundaries.
