“Let's learn how to walk with care for the natural environment and ecosystem of Iriomote Island and learn about its traditional culture.”


 “Let's follow the rules and be contentious  to protect Iriomote's sea, mountains, rivers, and the wildlife that lives there.”


“Let's spread the word about the natural wonders of Iriomote Island and the present challenges they face.”


 “Let's conserve the abundant nature and unique cultural heritage of Iriomote for children who will be its guardians in the future.”

To pass on the abundant nature and unique heritage of

Iriomote Island to the next generation.

Iroimote is part of the Yaeyama group in Okinawa Prefecture, lying about 2000 km southwest of Tokyo.


The islands cover an area of about 289 km2, Most of which is designated as a national park. The island is home to a wide range of rare wildlife and ecology including a virgin forest of subtropical flora and fauna, Japan’s largest mangrove forest, and the Iriomote wild cat, an endangered species of which only 100 remain. 


Another element of Iriomote island that cannot be overlooked is the rich traditional culture of its people, who have lived harmoniously with nature on the Island for hundreds of years. The changing of the seasons is celebrated with festivals such as the Shichi Festival which is registered as an important intangible cultural property of Japan.

Ethical tourism in Iriomote Island

Iriomote Island is home to only about 2400 residents however, in recent years it has become a popular tourist destination, drawing more than 300,000 visitors a year. This influx of tourists has led to a concerning rise in traffic accidents which endanger the vulnerable wild cat population and native vegetation of the island. 


The announcement of Iriomote's candidacy for designation as a World Natural Heritage site in 2020 is expected to draw even more attention and visitors to the island, adding the growing threat of over-tourism. 


To protect and pass on the precious nature of Iriomote to the next generation, all of us as tourists must know, learn, think, and act on these pressing issues.

Only 100 cats

Iriomote cats are endemic to the island and can be found nowhere else in the world. Only 100 cats remain and as such, they have been both designated as a nationally protected animal of Japan and listed as a critically endangered species. The biggest threat to the cats is the danger posed to them by cars. The increasing number of visitors to the island has caused a rise in the number of cats killed on the road. In 2018 alone nine wild cats were killed, the highest ever recorded in a single year.
