Shōnan Port Lighthouse, Maritime lighthouse in Fujisawa, Japan

The Shōnan Port Lighthouse is a white tower positioned along the Kanagawa Prefecture coastline that guides vessels approaching the harbor. The structure has a straightforward, functional design that makes it easy for seafarers to spot from a distance.

The lighthouse was installed on 26 September 1964 at the outer end of the breakwater of Shōnan Port on Enoshima. Its light was changed in 1974 to a green flash every four seconds, and in 2002 its position was fixed at 35°17′56″N 139°29′17″E. In 2016 it was chosen as a Civil Engineering Heritage site as one of Shōnan Port's main facilities.

The lighthouse stands at the outer end of the Shōnan Port breakwater on Enoshima. In 2016 the Japan Society of Civil Engineers selected it as one of the port's principal facilities and named it a Selected Civil Engineering Heritage site, so the structure is valued as engineering as much as for its light.

The lighthouse is accessible throughout the year and requires no entrance fee. The best way to reach it is by taking the Enoden Line to Enoshima Station, from where the location is easy to reach on foot.

In 2016 the lighthouse was chosen by the Japan Society of Civil Engineers as one of its Selected Civil Engineering Heritage sites, recognised as a key facility of Shōnan Port. Its light shines green, flashing two seconds on and two seconds off, and reaches 8.5 nautical miles.
