Did you know that 90% of Iriomote Island is covered in pristine, untouched subtropical jungle? This wild frontier of Japan offers one of the country’s last truly unspoiled natural environments, home to the critically endangered Iriomote wildcat found nowhere else on Earth. As part of the Yaeyama Islands in Okinawa Prefecture, this remote paradise combines dense mangrove forests, crystal-clear rivers, and vibrant coral reefs into an adventure traveler’s dream destination.
Getting to Iriomote Island
Reaching Iriomote Island requires a bit of planning, as there is no airport on the island itself. The journey is part of the adventure, taking you progressively further from Japan’s urban centers into its wild southern frontier.
Step-by-Step Journey
- Fly to Ishigaki Island (New Ishigaki Airport) from major Japanese cities like Tokyo, Osaka, or Naha
- Take a 10-minute bus or taxi ride from Ishigaki Airport to Ishigaki Port
- Board a ferry from Ishigaki Port to either Uehara Port (northern Iriomote) or Ohara Port (southern Iriomote)
- The ferry journey takes approximately 40-50 minutes
Ferries run regularly throughout the day, with the first departure typically around 7:00 AM and the last return around 5:30 PM. During peak season (July-September), it’s advisable to book your ferry tickets in advance to secure your preferred time slot.
