Japan
Subtropical jungle covering 90% of an island where the wildcat skulks and no road crosses.
Ninety per cent of Iriomote is jungle, and the jungle is not negotiating. Mangrove rivers twist inland beneath canopies so dense the water runs black. The Iriomote wildcat — fewer than a hundred remain — skulks through the undergrowth at dusk. No road crosses the island's interior; the only way through is by kayak or on foot.
Iriomote is the largest of the Yaeyama Islands and the second largest in Okinawa Prefecture, yet its population hovers around 2,400, clustered in coastal settlements. The island's subtropical rainforest was designated part of Iriomote-Ishigaki National Park and is included in the Amami-Ōshima, Tokunoshima, Northern Okinawa, and Iriomote UNESCO World Heritage Site inscribed in 2021. The Urauchi River, Okinawa's longest, is navigated by kayak through mangrove corridors to reach jungle waterfalls. The Iriomote cat, a critically endangered subspecies discovered in 1965, is found nowhere else on Earth.
Solo
Kayaking the Urauchi River alone, with only mangrove roots and bird calls for company, ranks among Japan's wildest solo experiences. The jungle demands self-reliance and rewards it.
Friends
River kayaking, jungle trekking to waterfalls, and night safaris searching for the Iriomote cat give a group of friends an expedition that feels genuinely remote — because it is.
