Onna is Okinawa's premier beach resort village, stretching along approximately 20 kilometers of coastline on the western shore of the Okinawa Main Island, roughly 30 kilometers north of Naha.
It is the most developed and celebrated resort destination on the island, home to the greatest concentration of luxury hotels, beach resorts, and water sports facilities in all of Okinawa Prefecture.
The village faces the East China Sea along its entire western edge, and the waters offshore are among the clearest and most biologically rich in Japan. The coral reefs running parallel to the Onna coastline support an extraordinary diversity of marine life and are the primary reason the area has become one of the top scuba diving and snorkeling destinations in the entire Asia-Pacific region.
The most famous diving site in Onna is Maeda Point (Cape Maeda), a rocky headland where divers and snorkelers enter directly from the shore and descend into a spectacular underwater landscape of coral arches, caverns, and tropical fish.
It is consistently rated among the best shore diving spots in Japan and draws visitors from around the world throughout the year.
Cape Maeda is accessible to swimmers and snorkelers of all experience levels, with shallow reef areas suitable for beginners and deeper formations further offshore, attracting more experienced divers. The clarity of the water here is particularly extraordinary, with visibility often exceeding 30 meters on calm days.
The coastline of Onna is lined with some of the finest resort hotels in Japan, ranging from internationally branded luxury properties to boutique beachfront ryokan.
The Busena Terrace, ANA InterContinental Manza Beach Resort, and Renaissance Okinawa Resort are among the most celebrated properties, each offering private beach access, multiple pools, and comprehensive water sports facilities.
Manza Beach, located at the northern end of the village near Cape Manza, is one of the most beautiful and recognizable beaches in Okinawa. The vivid turquoise water, white sand, and striking natural rock formations just offshore create a scene that appears in much of Okinawa's tourism imagery. The cape itself juts dramatically into the East China Sea and offers panoramic coastal views.
The underwater landscape off Cape Manza is equally impressive, with a famous dive site known as Manza Dream Hole, a large underwater cavern descending to depths favored by experienced divers seeking one of the most dramatic underwater experiences in the region.
Onna is also well known for its sea grape (umi-budo) cultivation, a type of edible green seaweed native to Okinawa that is farmed in the village's coastal waters.
The small, bubble-like clusters of sea grape are a celebrated local delicacy with a distinctive texture and mild oceanic flavor, served fresh in restaurants and sold in shops throughout the village and wider island.
The Ryukyu Mura cultural village sits within Onna and offers visitors an immersive introduction to traditional Ryukyuan culture. Relocated historic Ryukyuan houses, live performances of Eisa drumming and dance, Sanshin music demonstrations, and hands-on craft workshops are all available within the complex, providing cultural depth alongside the beach-focused character of the surrounding resort area.
Onna no Eki Nakayukui Market is a popular roadside market along National Route 58 selling fresh local produce, Okinawan snacks, tropical fruits, and regional specialty foods. It is one of the best places along the resort coast to sample and purchase authentic local products directly from Okinawan farmers and producers.
The village is accessible from Naha by car via National Route 58 or the Okinawa Expressway, with journey times of approximately 45 minutes to 1 hour depending on the destination within the village. Public buses from Naha Bus Terminal serve the coastal route, but journey times are considerably longer.
