Guide
Tonaki Island is a small island covering 3.84 km², located approximately 58 km northwest of Okinawa Main Island. In 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 avenues. Additionally, it was designated as a Prefectural Natural Park in 1997, ensuring a rich and preserved natural environment. Please note that the island maintains a rustic atmosphere with very few modern facilities, such as convenience stores or large commercial centers.
While the exact origins of the village formation are not fully documented, archaeological evidence of human habitation exists on the northern hills (the 'Sato' area) at an altitude of approximately 80m. This 'Sato' is considered the predecessor to the current settlement. During the Ryukyu Kingdom era, Tonaki, much like Kumejima, Aguni, and Kerama, was under the jurisdiction of the Kume Magistrate. Following the Meiji era, it fell under the administration of Naha, and today it operates as the independent municipality of Tonaki Village. The 'Sato Ruins' on the island have yielded artifacts from the 14th to 15th centuries, including pottery, ceramics, ironware, and carbonized rice, proving a long history of human settlement.
The landscape of Tonaki Island is defined by its traditional red-tiled houses, Fukugi tree avenues, and white sand paths. At night, the village takes on a unique charm as footlights illuminate the paths, creating a serene atmosphere. The natural environment is also a major draw; sea turtles are frequently spotted in the surrounding waters, and visitors may observe them while walking along the coast during high tide. In the winter, you may even witness whale migrations. The island's topography is unique, formed by two merging mountains, resulting in distinct landscapes between the northern and southern areas.
Nature changes beautifully with the seasons. For instance, winter visitors may enjoy seeing whales passing through the waters. The evening atmosphere is also a highlight, as the village footlights create a soft, glowing landscape after sunset. The island is also an exceptional location for stargazing due to its minimal light pollution. Regarding transportation, the ferry schedule varies; during the summer season (April to October), certain afternoon departures to Naha operate on Fridays (including Saturdays for the year 2026), making day trips more feasible.
Visitors can engage in nature observation based on the island's rich biodiversity. Near the shores, sea turtles are a common sight, and you can observe various fish species near the reef edges. On land, the presence of coconut crabs (Yashi-gani) is also documented. Whether you are exploring the historical village or observing the unique geological formations, the island offers a deep connection to nature and history.
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 by ferry from Naha. For a faster alternative, access via helicopter taxi from Naha Airport is also available.
As there are almost no convenience stores or commercial facilities on the island, it is essential to bring your own beverages, snacks, and necessary supplies before arrival. Cash is highly recommended for ferry-related expenses and local services. For clothing, comfortable walking shoes and attire suitable for beach or village strolls are recommended. Since 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 required.
