Guide
Aguni Island is a small island with a circumference of approximately 12 km, located about 60 km northwest of Naha, Okinawa. The island's history is rooted in volcanic activity, with layers of lava and volcanic ash forming its foundation, now surrounded by beautiful coral reefs. The island is characterized by its diverse topography: limestone caves in the north, massive white tuff cliffs rising over 80m in the west, white sandy beaches in the east, and volcanic sediment deposits in the south. As a single-village island, it maintains a harmonious environment where nature and tradition live side by side.
The island continues to observe sacred rituals and festivals based on the traditional lunar calendar. In particular, the Lunar New Year is celebrated as the most significant event on Aguni Island. The very shape of the land was sculpted by the accumulation of lava and volcanic ash, creating the unique landscape seen today. Many sites on the island carry deep historical significance, preserving the cultural landscape of the region.
There are numerous spots throughout the island where you can feel the beauty of natural formations. In the northern part, the limestone caves feature a well-maintained walking path and a beautifully illuminated interior. To the west, the towering white tuff cliffs over 80m high offer a breathtaking view. The eastern side features Ugu Beach, known for its crystal-clear waters and white sand. From the Mahana Observatory, you can enjoy panoramic views of Okinawa Main Island and the surrounding islets. For divers, the area offers the spectacular sight of a Bigeye Scad (tarpon) tornado. Additionally, certain areas are designated as bird sanctuaries, where you may spot rare birds such as the Blue Whistling Thrush.
The best time to visit is from May to August, which is ideal for diving and beach activities. If you wish to experience the island's unique cultural heritage, it is highly recommended to check the lunar calendar to coincide with the traditional New Year festivities. During the daytime, the colors of the cliffs and beaches are most vivid, and in the evening, the observatory offers stunning sunset views.
Aguni Island offers a wide range of activities centered on its natural environment. Underwater, you can experience the thrill of diving to witness the Bigeye Scad tornado. On land, you can explore the illuminated paths of the limestone caves, enjoy the scenery from the observatory, or relax on the beaches. Because the entire island is a rich natural environment, nature observation is a key part of the experience.
