The park is home to the flightless Okinawa rail (Gallirallus okinawae), a species found nowhere else on Earth.
The forest canopy is primarily composed of Castanopsis sieboldii, a species of evergreen chinkapin.
The area features karst limestone formations that date back to the Permian period.
Yanbaru is part of a complex of four Japanese locations inscribed as a UNESCO World Heritage site for their biodiversity.
The name 'Yanbaru' historically refers to the mountainous, forested region of northern Okinawa.
Yanbaru National Park encompasses the northernmost region of Okinawa Island, Japan, featuring one of the largest subtropical evergreen forests in the country. It was designated as a UNESCO World Heritage site in 2021 for its outstanding universal value regarding biodiversity. The park protects rare endemic species including the Okinawa rail, the Yanbaru long-armed scarab beetle, and the Okinawa spiny rat. The landscape is defined by its rugged karst limestone terrain, waterfalls, and dense mangrove forests along the coast. It serves as a vital hydrological catchment for the island's water supply. The area includes various hiking trails that navigate through ancient laurel forests. Much of the region is protected as a wilderness area to maintain ecological integrity. It is the primary habitat for the endangered flightless Okinawa rail bird.

Wear sturdy, non-slip hiking boots as trails are often wet and muddy due to high humidity.
Bring binoculars to spot endemic bird species like the Okinawa rail, especially during early morning hours.
Always stay on marked trails to prevent soil erosion and protect the sensitive forest floor habitat.
Avoid driving on forest roads at night to prevent collisions with rare, flightless nocturnal animals; avoid visiting during typhoons.
Do not touch, feed, or disturb wildlife; remove all trash as there are no public bins; stay strictly on marked paths.
