Amami-Oshima Island, Tokunoshima Island, Northern part of Okinawa Island, and Iriomote Island

By Brandon

What is this group of islands in Japan?

Amami-Oshima Island, Tokunoshima Island, Okinawa Island and Iriomote Island are four islands located in Southern Japan’s Kagoshima and Okinawa Prefectures. What makes these subtropical islands unique are the many endemic species that occur on these islands and nowhere else on Earth.

Amami and Tokunoshima belong to Kagoshima Prefecture while Okinawa and Iriomote belong to Okinawa Prefecture. All these islands belong to an archipelago that is a part of the Ryukyu Islands.

Why are these islands a UNESCO World Heritage site?

Covering 42,698 hectares (165 square miles) of rainforest and natural beauty, these four islands were added as a World Heritage site in 2021. The ecosystem here is unique and there are several endemic species found on these islands and nowhere else in the world. The Amami Rabbit is only found on Amami-Oshima and Tokunoshima, the Iriomote Wildcat can only be found on the island of Iriomote, and animals such as the Okinawan Woodpecker, Kuroiwa’s Ground Gecko, and Okinawa Rail are only found in the northern portion of the main island of Okinawa. These are important habitats that are home to many endangered species and deserve protection.

What can you expect on a visit to these islands in Japan?

My travels to Iriomote Island and Northern Okinawa are always an adventure. You get a sense of exploration here as you kayak, canoe or SUP through mangrove forests, hike up waterfalls, and explore the beautiful beaches. Don’t expect to see many of the endangered wildlife species as they are mostly nocturnal and shy.

Okinawa does have an Okinawan Rail Bird Museum that has a rail bird, so your hopes of seeing one in captivity are guaranteed.

Are these islands worth visiting?

Amami-Oshima Island, Tokunoshima Island, Okinawa Island, and Iriomote Island are all well worth a visit. If visiting from mainland Japan, it is a night and day difference from the beautiful shrines and temples found on mainland Japan. Visitors come to this part of Japan to experience the rainforests, beaches, and local culture.

Keep in mind that visiting these islands is not for everyone as you will be out in nature the majority of the time, possibly in uncomfortable conditions.

Tips for visiting the islands

Amami-Oshima Island, Tokunoshima Island, Okinawa Island, and Iriomote Island are located in the country of Japan but do take effort and planning to visit. I’ve been to Iriomote Island and the Northern part of Okinawa’s main island.

  • To get to Iriomote Island, you have to take a flight to another island called Ishigaki, and from there it’s an hour-long ferry ride.
  • The northern part of Okinawa Island is easier to reach, but a rental car is a must.
  • There are ferries from mainland Japan and Okinawa that go to Amami Oshima and Tokunoshima.

The four islands aren’t exactly close to each other. Depending on the length of travel it might be worth it to only visit one or two of these islands.

If visiting Iriomote or the northern part of Okinawa, plan to be in nature most of the time and bring clothes for all types of weather conditions. There are tours in Iriomote and Okinawa that you can purchase online to explore these remote places. There are also guides who are willing to take groups out at night to find some of these endemic species.

Since visitors come here to enjoy nature and being outside, wear clothing that is appropriate for outdoor activities and bring sun protective gear. The sun in this part of Japan is no joke: it’s best to wear a hat, sunglasses, sun sleeves, and don’t forget sunblock.
