Kerama Shoto

Kerama Shoto National Park encompasses a stunning archipelago of more than 30 islands and islets located approximately 30-40 kilometers west of Okinawa's main island in the East China Sea. Designated as Japan's 31st national park on March 5, 2014, it protects 3,520 hectares of terrestrial area and an impressive 90,475 hectares of marine environment, making it predominantly a marine protected area. The park is renowned for its exceptionally clear waters, vibrant coral reefs, pristine white sand beaches, and rich marine biodiversity. The Kerama Islands have become internationally famous as one of Asia's premier diving and snorkeling destinations, with visibility often exceeding 50 meters and water displaying mesmerizing shades of "Kerama Blue." The archipelago serves as an important breeding ground for humpback whales, which migrate to these warm waters each winter, and supports critical sea turtle nesting sites. The islands' subtropical climate, dramatic coastal landscapes, and relatively undeveloped character create a paradise for marine conservation and eco-tourism. The park's establishment represented a significant milestone in Japan's efforts to protect marine ecosystems and promote sustainable island tourism.

The Kerama Islands have a complex history shaped by their strategic location and natural beauty. Historically sparsely populated, the islands saw increased settlement during the Ryukyu Kingdom period when they served as waypoints for maritime trade routes. During World War II, the islands became the site of tragic events, with the Battle of Kerama Islands in March 1945 resulting in significant civilian casualties and military conflict. Post-war recovery was slow, with traditional fishing and small-scale agriculture sustaining island communities. The islands' exceptional marine environment began attracting divers in the 1970s and 1980s, gradually building a reputation as a world-class diving destination. This growing recognition of the archipelago's ecological value led to campaigns by local communities, conservation organizations, and tourism operators to secure formal protection. After years of advocacy and ecological surveys documenting the area's outstanding coral reef systems and marine biodiversity, the Japanese government designated Kerama Shoto as a national park in 2014. The designation aimed to balance conservation of fragile marine ecosystems with sustainable tourism development, recognizing both the area's ecological significance and its economic importance to local communities relying on nature-based tourism.

Kerama Shoto National Park is highly accessible compared to many of Japan's more remote protected areas, with regular ferry services connecting the main islands to Naha, Okinawa's capital city. High-speed ferries reach Tokashiki Island in about 35 minutes and Zamami Island in 50-70 minutes, with multiple daily departures making day trips feasible. The inhabited islands of Tokashiki, Zamami, and Aka offer a range of accommodation options from budget guesthouses to resort hotels, along with restaurants, dive shops, and equipment rental facilities. Visitors can explore numerous pristine beaches including Aharen Beach, Furuzamami Beach, and Tokashiku Beach, most accessible on foot or by rental bicycle. The park's primary attractions are underwater, with dozens of established dive sites suitable for all experience levels and excellent snorkeling opportunities directly from beaches. Whale watching tours operate from January to March when humpback whales breed in surrounding waters, offering spectacular encounters with these marine giants. Kayaking, stand-up paddleboarding, and glass-bottom boat tours provide alternative ways to experience the marine environment. Visitor centers on Zamami and Tokashiki islands provide information about the park's ecology, conservation, and sustainable tourism practices. Summer is the peak season, but spring and fall offer pleasant weather with fewer crowds.

Conservation at Kerama Shoto National Park centers on protecting fragile coral reef ecosystems facing multiple pressures from climate change, overtourism, and marine pollution. The park has implemented strict regulations on diving and snorkeling activities, including designated zones where anchoring is prohibited to prevent damage to coral formations. Marine park rangers conduct regular reef health assessments and monitor key indicator species to track ecosystem changes and inform adaptive management strategies. Climate change poses a significant threat through coral bleaching events, ocean acidification, and rising sea temperatures, prompting research into coral resilience and potential restoration techniques. Sustainable tourism initiatives work with dive operators and accommodation providers to implement best practices, including limits on visitor numbers at sensitive sites and education programs about responsible reef interaction. The park plays a crucial role in sea turtle conservation, with monitoring and protection of nesting beaches for loggerhead and green turtles, alongside community education about reducing threats from artificial lighting and beach development. Humpback whale protection is enhanced through vessel approach regulations during breeding season, ensuring tourism activities don't disrupt critical behaviors. Marine debris removal programs engage volunteers and local communities in beach cleanups, addressing pollution from both local sources and ocean currents. The park's management recognizes that long-term conservation success depends on maintaining the economic benefits that motivate local communities to support protection measures.
