Emerald Beach, officially Kokuei Okinawakinenkoen Emerald Beach, is a prominent feature of the Ocean Expo Park in Motobu, Okinawa. It is renowned for its exceptional water quality, often rated 'AA', and its unique status as Japan's only reef beach. The beach is divided into three distinct areas: 'Playing Beach', 'Recreation Beach', and 'Viewing Beach', catering to different visitor preferences. Its picturesque setting, with views of Iejima Tacchu (Castle Mountain) across the sea, makes it a popular spot for both relaxation and photography.
Visitors consistently praise the beach for its crystal-clear, calm, and beautiful blue waters, making it ideal for families with small children. The presence of lifeguards and safety nets against jellyfish provides a sense of security. Many reviewers highlight the convenience of free amenities such as showers, changing rooms, and ample parking. The beach's proximity to the Churaumi Aquarium is a major draw, with many suggesting combining a visit to both. The sunset views are frequently mentioned as particularly splendid, offering excellent photo opportunities.
For a comfortable visit, it's advisable to bring water shoes due to the sand containing coral and shells, which some find coarse or prickly. While sunbeds and parasols were previously available for rent, recent reviews indicate this service may have been discontinued, so bringing your own towel and sun protection is recommended. The beach is generally less crowded in the mornings, offering a more tranquil experience. Swimming is typically allowed from April to October, with lifeguards on duty during these months. Outside of the swimming season, the beach is still beautiful for walks and enjoying the scenery, but swimming may be prohibited.
Emerald Beach is conveniently located within the Ocean Expo Park, adjacent to the Churaumi Aquarium. For those driving, parking lot P9 is recommended as the closest option. If staying at the Hotel Orion Motobu, direct access to the beach is available via a gate during the day, but visitors should note its closing time to avoid a long detour. The beach is also accessible via the aquarium's trolley for those who prefer not to walk. Public transport options within the park are generally good, connecting various attractions.
Some visitors express disappointment, noting that the beach can be smaller than expected or that the sand isn't as fine as other famous beaches. A common complaint is the strict enforcement of rules, such as staying within designated swimming areas and restrictions on activities like snorkeling. Reviewers also mention occasional trash or broken glass, advising caution when walking barefoot. To mitigate these issues, visiting during peak season (April-October) ensures lifeguard presence and potentially better maintenance. Always check for current rules and conditions upon arrival.
