Iriomote Island

Iriomote Island is a largely forested island in Okinawa Prefecture’s Yaeyama group, known for dense subtropical jungle, mangrove coasts and endemic wildlife. It is part of Iriomote-Ishigaki National Park and notable for the rare Iriomote cat.

Long inhabited by Ryukyuan communities, the island has been managed for conservation since the national park designation and has small, dispersed settlements that support tourism and local fishing. Conservation measures protect key habitats and restrict development in sensitive areas.

Iriomote lies southwest of Okinawa’s main island group and is reached by ferry or small plane from Ishigaki; local transport on the island is limited and many visitors join organised excursions from the ports.

• Iriomote cat: Home to the critically endangered Iriomote cat, an endemic wild feline that is the island's most famous conservation symbol and is rarely seen in the wild.
• Access: Most visitor access is by ferry from nearby Ishigaki, with local boat operators running river tours and guided treks to waterfalls and mangroves.
