Iriomote Island (西表島, Iriomote-jima) is the largest island of the Yaeyama chain, yet over 90% of its land is covered in dense subtropical rainforest and mangrove swamps. With only one main road along the east coast, most of the island remains untouched wilderness, often called Japan’s last frontier.
A 30–40 minute ferry ride from Ishigaki (to either Ohara or Uehara Port) brings you into a world of rivers, waterfalls, rare wildlife, and unspoiled beaches. For travelers seeking both adventure and serenity, Iriomote is unlike anywhere else in Japan.
The Unique Nature of Iriomote
Mangrove Forests – The island has Japan’s largest mangrove ecosystem, where rivers meet the sea in an otherworldly landscape. Kayaking and river cruises are the best ways to explore.
Explore Iriomote’s vast mangroves by kayak or boat.
Waterfalls and Rivers – From the mighty Pinaisara Falls (the tallest in Okinawa at 55 m) to hidden jungle cascades, Iriomote’s rivers invite trekkers and paddlers alike.
Beaches and Coral Seas – Secluded shores like Hoshizuna Beach (famous for star-shaped sand grains) and Ida Beach are perfect for stargazing, snorkeling, or simply relaxing far from crowds.
Remote and secluded Ida Beach Iriomote you can only reach by small boat.
Iriomote Yamaneko – The Island’s Secret Guardian
The Iriomote Yamaneko (西表山猫), a wild cat discovered in 1965, is one of the rarest animals in the world and exists only on this island. Sightings are rare, especially in daylight, but road signs remind drivers to slow down at night to avoid accidents. Protecting the Yamaneko is a shared responsibility of all visitors.
The critically endangered Iriomote Yamaneko (wild cat) is endemic to Iriomote’s dense forests – only about 100 of these elusive felines remain in the wild
Things to Do on Iriomote
Kayaking & SUP – Paddle through mangroves and rivers like Urauchi or Nakama, often combined with hikes to jungle waterfalls.
Snorkeling & Diving – Coral reefs around Barasu Island and coral gardens off northern Iriomote offer world-class underwater scenery.
Trekking – Experienced hikers can explore deep jungle routes, but guided tours are recommended for safety.
Cycling Adventure – Rent a bike on Ishigaki, take it on the ferry, and try the 60 km ride from Ohara to Uehara along the island’s only road.
Stargazing – Iriomote’s dark skies make it one of the best places in Japan to watch shooting stars.
