The Kaichu-doro causeway was originally constructed as a privately funded project in the 1970s before being transferred to the local government.
The waters surrounding the beach are part of a shallow lagoon system, making them ideal for beginners learning wind-dependent water sports.
The area serves as the gateway to the four 'Islands of the Sea Road,' each maintaining distinct traditional Okinawan cultural practices.
The beach is artificial in nature, created as part of the land-reclamation and coastal infrastructure development of Uruma City.
Mid-Sea Road Beach is located along the Kaichu-doro (Mid-Sea Road), a 4.7-kilometer causeway connecting the Okinawa mainland to the islands of Henza, Miyagi, Ikei, and Hamahiga. The beach is situated on the mainland side of the causeway, offering direct access to the shallow, turquoise waters of Kin Bay. The area serves as a primary hub for marine sports, including kite surfing and windsurfing, due to consistent coastal breezes. The beach provides extensive parking facilities and public restrooms directly adjacent to the causeway. Tidal variations significantly impact the shoreline, with the beach appearing expansive at low tide and receding closer to the sea wall at high tide. The site is part of the larger Uruma City recreational development, integrating beach access with adjacent local market facilities and dining.

Check the local tide charts before arriving, as the beach loses most of its walkable sand surface at high tide.
Bring water shoes, as the shallow seabed can feature coral fragments and rocky patches common in Okinawan coastal waters.
Visiting during high tide if you intend to relax on the sand, as seating areas become extremely limited.
Avoid entering nearby private agricultural land or beach facilities designated for local fishing cooperatives.
