Overview (history, characteristics, attractions)
Iriomote Island (Taketomi Town, Okinawa Prefecture) is the largest island in the Yaeyama Islands, and a natural treasure trove of some of Japan's finest subtropical virgin forests and mangroves. Island culture has thrived here since ancient times, and village life has continued to be based on fishing and agriculture. The island's interior is dominated by steep mountains and dense forests, while the periphery is surrounded by coral reefs, preserving rare flora and fauna and a diverse marine ecosystem.
The attraction is the opportunity to experience untouched nature. There are plenty of activities available on land and sea, including kayaking through the mangrove forest, sightseeing on the Urauchi River, trekking to Pinaisara Falls, and snorkeling and diving in the crystal-clear coral reefs. You may even encounter endemic species such as the Iriomote wildcat and rare ecosystems.
Highlights
- Pinaisara Falls — One of the largest waterfalls in Okinawa Prefecture. You can get close to the basin from the observation deck or on a kayak and trekking tour (the view may vary depending on the season and water level).

Things to be aware of (crowds, manners, seasonal precautions, etc.)
- Nature Conservation and Manners: As there are many protected species, such as the Iriomote wildcat, feeding or approaching them is prohibited. Collecting coral or other living creatures is also strictly prohibited. Please follow the designated trails and signs.
- Consideration for wildlife: There is a risk of collision with the Iriomote cat when driving at night, so you should take care to slow down and use your headlights carefully.
- Weather and sea conditions: During typhoon season (mainly summer to autumn), tours and flights are likely to be cancelled. Trekking and river activities can be dangerous during the rainy season and heavy rains.
- Insect prevention and equipment：Because it is a subtropical region, be careful of mosquitoes, black flies, ticks, and freshwater creatures (including leeches). Bring long sleeves, long pants, insect repellent, a change of clothes, and shoes that can get wet.
- On-site facilities: Hospitals, ATMs, and commercial facilities are limited, so it's a good idea to bring along some regular medications and a small amount of cash. Transportation may be almost nonexistent at night.
- Tour use: For safe and efficient mountain trails, river rafting, waterfall climbing, etc., it is recommended to join a tour with a professional guide. A guide is especially recommended for first-time visitors and in rainy weather.
- congestion: During Golden Week, summer vacation, and other long weekends, the number of tourists increases, and accommodations and tours tend to fill up. Make your reservations early.
- Environmentally friendly behavior: Please be mindful of actions that do not harm nature, such as using reef-safe (sunscreen), always taking your trash home with you, and observing quietly.
Note: When planning your trip, be sure to check the latest ferry times, weather information, entry restrictions (protected areas), and whether or not there are any tours available in advance. Iriomote Island is an island where nature plays a central role, so you can enjoy it best by taking your time and going with the rhythm of nature.
