The small island chain that forms in the south of the Japanese archipelago is thought to have originally been part of the Eurasian Continent some 12 million years ago. As a result, the diverse flora and fauna that originated from the continent have followed a unique evolutionary path, and can still be found on the islands today. Amami Oshima Island, Tokunoshima Island, the northern part of Okinawa Island, and Iriomote Island (Amami and Okinawa) have a particularly unique ecosystem and are teeming with rare species, and this area was registered as a World Natural Heritage site in 2021.

Due to the presence of dangerous creatures in nature, such as the habu snakes, it is important to travel with a tour guide who is well accustomed to local etiquette and the natural environment. When entering natural surroundings in the area, it is recommended that you wear long sleeves, long pants, and boots or sneakers. In addition, visitors are asked not to randomly pick plants, catch animals, or bring plant seeds or animals from outside the island. Even the smallest changes could break chains in nature and cause major environmental impacts.

Trekking is a great way to get up close and personal with the diverse flora and fauna present. Experience a dynamic sense of nature with the Kinsakubaru Forest and Native Mangrove Forest on Amami Oshima Island, and the expansive Yanbaru Forest in the northern part of Okinawa Island. Some of the valuable endemic animal species found in this region are nocturnal in nature. Night tours under a starry sky are also provided on Tokunoshima Island and Iriomote Island. Why not experience the many flavors of Amami and Okinawa by going trekking by day, and taking a night tour after the sun goes down?
