Sesoko Beach is located on Sesoko Island, connected to Okinawa's main island by the Sesoko Bridge, making access straightforward. From Naha, drive north approximately 90 minutes via the Okinawa Expressway to Motobu Peninsula. A rental car is highly recommended as public transportation to the island is limited.

Sesoko Beach has basic facilities including seasonal food stands and beverage vendors during peak season. The island itself has a few small restaurants and cafes serving local cuisine and casual meals. For more dining variety, nearby Motobu town offers numerous restaurants within a short drive. Accommodation options on Sesoko Island include small guesthouses, vacation rentals, and a few hotels. Many visitors stay in Motobu or Nago areas for more lodging choices. Bringing snacks and drinks is advisable, especially during off-peak seasons when vendors may be limited.

Sesoko Beach's exceptional water clarity results from its island location surrounded by ocean currents that constantly refresh the water. The white sand bottom reflects light, enhancing the brilliant blue and turquoise colors. Being positioned away from river mouths means no sediment runoff to cloud the water. The island's relatively undeveloped nature helps preserve water quality. The beach faces the East China Sea with minimal industrial activity nearby. This combination creates the crystal-clear conditions that make Sesoko Beach famous among Okinawa's beaches.
