Tonaki Island is a small island covering 3.84 km², located approximately 58 km northwest of Okinawa Island. In the year 2000, it was officially designated as a Preservation District for Groups of Traditional Buildings due to its cultural significance. The island maintains a traditional Okinawan landscape characterized by red-tiled roofs, white sand paths, and lush Fukugi tree groves. Additionally, it was designated as a Prefectural Natural Park in 1997, highlighting its rich biodiversity. As a remote island, it lacks modern amenities like convenience stores or large commercial facilities, allowing visitors to experience a truly authentic and undisturbed environment.
While the exact origins of the village formation are not fully documented, archaeological evidence of ancient settlements can be found in the 'Sato' area, a hilly region approximately 80m above sea level in the north. This area is considered a precursor to the current village. During the Ryukyu Kingdom era, Tonaki was under the jurisdiction of the Kume Magistrate, similar to Kumejima, Aguni, and the Kerama Islands. Following the Meiji era, it fell under the administration of Naha and eventually became the independent municipality of Tonaki Village. The 'Sato Ruins' on the island have yielded artifacts from the 14th to 15th centuries (Gusuku period), including pottery, ceramics, iron tools, and carbonized rice, proving a long history of human habitation.
The visual charm of Tonaki Island lies in its harmonious blend of red-tiled houses, Fukugi tree-lined streets, and white sand paths. At night, the village takes on a magical atmosphere thanks to the footlights installed along the paths, creating a unique nocturnal landscape. Nature lovers will appreciate the rich marine life; sea turtles are frequently observed, especially during high tide along the coast. In winter, visitors may even catch a glimpse of migrating whales. The island's topography is also unique, formed by two merging mountains, resulting in distinct landscapes between the northern and southern regions.
Nature changes beautifully with the seasons. In winter, you might witness whale migrations in the surrounding waters. As evening falls, the village transforms with the soft glow of footlights, making it a perfect time for a quiet stroll. The island is also an exceptional spot for stargazing, offering a clear, unobstructed view of the night sky. Regarding transportation, the ferry service from Naha includes a Friday afternoon-departure (including Saturdays for the year 2026) during the summer season from April to October, making day trips more feasible during these months.
Visitors can enjoy observing the local ecosystem and natural wonders. Along the coastline, sea turtles are a common sight, and the reef breaks offer excellent opportunities for observing various fish species. On land, you may even spot coconut crabs. Whether it is observing the unique topography or walking through the historic village, the island offers a deep connection to traditional Okinawan life.
Tonaki Island is geographically positioned near Aguni Island to the north, the Kerama Islands to the southeast, and Kumejima to the west. The most common way to reach the island is via ferry from Naha. For a faster and more premium experience, helicopter taxis are also available from Naha Airport.
Because there are almost no convenience stores or commercial facilities on the island, it is essential to bring your own food, drinks, and necessary supplies. For payments, please carry sufficient cash, as many local services and ferry-related expenses require it. Wear comfortable, practical clothing and sturdy shoes suitable for walking on sandy paths or through the village. As the island is a designated natural park, please respect the environment and follow local etiquette. If you plan to use the helicopter taxi service, advanced reservations are mandatory.
