Iriomote Island, the largest of the Yaeyama Islands and one of Japan’s last great wildernesses, is around 90% covered in dense subtropical jungle and mangrove forest — earning it the nickname ‘the Galapagos of the East’. Kayaking through its mangrove-lined rivers is the classic way to experience this remarkable natural environment. Guided tours paddle up winding tidal rivers such as the Urauchi and Nakama, gliding quietly between towering mangrove trees whose tangled roots arch over the water, past lush jungle alive with birds, crabs and other wildlife. Many tours combine kayaking with a jungle trek to hidden waterfalls (like the beautiful Pinaisara Falls, Okinawa’s tallest) for a swim and a picnic. Tours cater to various fitness levels, including beginners and families, and knowledgeable guides explain the unique ecosystem. Adventurous, peaceful and immersive, mangrove kayaking on Iriomote is a highlight of the Yaeyama Islands and a world away from Okinawa’s beach resorts.
