Hanabuchi Lighthouse, Maritime navigational structure in Shichigahama, Japan.

Hanabuchi Lighthouse is an unmanned light on the south-east slope near the summit of Mount Goten in Hanabuchi-hama, Shichigahama, facing Sendai Bay. It was built over two years at a total cost of 15.78 million yen and first lit on 27 October 1964. Three small stone shrines marking the former site of Nosebetsu Shrine stand just north of the tower.

Hanabuchi Lighthouse first shone on 27 October 1964, after two years of construction costing 15.78 million yen. It stands on the southeast slope near the summit of Goten-yama, on the site once occupied by the grounds of Hanabusa Shrine before that shrine moved to Tarumizu-yama. Three stone shrines north of the tower mark the shrine's former location.

The lighthouse stands near the former grounds of Hanabuchi Shrine on Mount Goten, and three small stone shrines north of the tower mark the shrine's old site. Offshore, at the Oine reef, the Oine Myojin deity is honoured each year on the first day of the sixth lunar month with an offering of abalone; abalone fishing there is forbidden.

The lighthouse is unmanned and its maintenance road is closed to ordinary vehicles; the shortcut through the Takayama foreign summer resort crosses private land and is off-limits to outsiders. By bus, take the Shichigahama town bus "Gururinko" to the Tate-shita stop and walk about 20 minutes. By car, follow the signboards for Hasekoto Shrine to the free car park in front of the shrine, then continue on foot following the lighthouse signs.

The lighthouse stands on the slope of Mount Goten, next to three small stone shrines marking the former site of the Hanabusa Shrine, which was moved here after the 869 Jogan earthquake submerged its original offshore rock. The boundary between the Shiogama and Sendai port areas is drawn along a line running 124 degrees from the lighthouse, the same line that links it to the Daikon rock.
