Arasaki, Coastal park in Yokosuka, Japan

Arasaki is a municipal scenic park (fūchi kōen) of Yokosuka in the Nagai district, on a small cape jutting into Sagami Bay. A seaside promenade runs along the shore past sheer cliffs, sea caves, reefs and inlets; on the higher ground are the Sunset Hill, Sea Breeze Hill and Picnic Hill viewpoints. A long low tan-walled building with a band of dark windows stands above the rocks, crossed by steel-railed walkways and a concrete bridge.

The park was created by Yokosuka City as a scenic urban park (fūchi kōen) on the Arasaki promontory in the Nagai district, protecting the natural shoreline while adding paths and hilltop viewpoints. The city manages the site, and the surrounding Nagai area includes Nagai Fishing Port and the Nagai Seaside Park Soleil Hill.

The name Arasaki refers to the small cape jutting into Sagami Bay, and the park was laid out to protect this headland and its surroundings while opening them to walkers. From the hills above the shore, on clear days, visitors can pick out Mount Fuji, the Hakone mountains and the Amagi range to the west.

The park is free to visit and has parking for approximately 90 vehicles with different rates for weekdays and weekends. The paths are clearly marked and work well for a daytime visit.

The park's paved promenade runs along the shore, letting walkers pass close to the cliffs, sea caves, rock reefs and inlets that the coastline forms. On clear days the view west takes in Mount Fuji, the Hakone mountains and the Amagi range.
