Kayaking in Iriomote

Iriomote sits far out in the Yaeyama group, closer to Taiwan than to Tokyo, and looks nothing like the rest of Japan. Ninety percent of it is subtropical jungle — mangrove estuaries, waterfalls, and forest so thick the rivers serve as the roads. Somewhere in it lives the Iriomote cat, a wildcat so rare most residents have never laid eyes on one.

The classic crossing pairs water and foot: you paddle up the Urauchi River between walls of mangrove, then walk the trans-island trail through the interior to the far coast, camping on beaches with no road behind them. It is hot, wet, tangled work, and the sense of being somewhere genuinely wild — a place that only became a UNESCO site in 2021 — is the whole point.

That listing brought visitor caps and guide requirements for parts of the interior, and the rules have tightened since. Confirm current access before you plan; some sections can no longer be entered without an accredited guide.

RE-CHECK. Iriomote introduced visitor caps and guide requirements for parts of the interior after its UNESCO listing, and the rules have been tightened since. Confirm current access before planning.
