Iriomote Island: UNESCO World Heritage Omija River Canyoning & Eco-Adventure
Meet your guide at Uehara Port, gateway to Iriomote Island, a wild landscape known as the “Galapagos of the East.” This tour takes you into the heart of a UNESCO World Heritage Site to explore one of Japan's last untamed wildernesses through canyoning.
Head to the stunning Omija River, a natural water park carved into ancient rock over millennia. Under your guide's expert supervision, jump from natural rock platforms into deep emerald pools, slide down small moss-covered waterfalls, and navigate unique limestone formations. Canyoning is a full-body way to feel the island's raw energy.
Your professional guide knows every current and crevice of the river, so you can focus on the fun and the jungle scenery. Your guide will also capture every leap, slide, and smile with a waterproof camera, and all photos are provided free of charge.
Our eco-tour follows “Leave No Trace” principles to protect Iriomote's pristine waters and mangroves for generations to come. Perfect for anyone who wants a physical challenge while respecting the island's natural heritage.
