The Yanbaru Forest — Okinawa's World Natural Heritage, Walking the Subtropical Primeval Forest

Densely growing subtropical trees, the voices of wild birds echoing over the moist earth, and the murmur of clear valley streams: "Yanbaru," spreading across the northern part of Okinawa's main island, is a precious forest area registered as a World Natural Heritage Site in 2021. It is a treasure trove of endemic creatures found only here, such as the flightless bird the Okinawa rail (Yanbaru kuina) and the rare woodpecker the Okinawa woodpecker (Noguchigera). Walking wrapped in the deep green, you can feel with your whole body the rich breath of nature unique to the subtropics.

World Natural Heritage Yanbaru

"Yanbaru" is a word meaning "a region where mountains continue," and refers to the forest zone spanning Kunigami Village, Ogimi Village, and Higashi Village in the northern part of Okinawa's main island. Subtropical laurel forest spreads out, and it is a treasure trove of biodiversity where a wide variety of flora and fauna live. Its global value was recognized, and in July 2021 it was registered as a UNESCO World Natural Heritage Site as "Amami-Oshima Island, Tokunoshima Island, Northern part of Okinawa Island, and Iriomote Island."

A Treasure Trove of Endemic Species

The Yanbaru forest is home to many endemic species found only here. It is a paradise of precious creatures, such as the flightless bird that walks the ground, the "Okinawa rail," the beautiful red-headed woodpecker, the "Okinawa woodpecker," and one of the world's largest beetles, the "Yanbaru long-armed scarab beetle." To protect the rare species, rules and manners are required for observation, and entering areas other than designated ones and collecting flora and fauna are prohibited.

Trekking and Nature Observation

In Yanbaru, trekking and nature observation by joining a guided tour are popular. There are various ways to enjoy it, such as walking the promenades of the primeval forest, hiking toward waterfalls, and searching for nocturnal creatures on a night tour. Walking while learning about rare flora and fauna and the workings of the forest under the guidance of an experienced guide deepens your understanding of nature. Because the Okinawa rail sometimes crosses roads, when driving observe the speed limit and watch for animals darting out.

Access and Basic Information

For access, it is roughly two to three hours by car from Naha. It is common to exit at the Kyoda IC on the Okinawa Expressway and head north on National Route 58 toward Kunigami Village. There are also buses for public transport, but services are limited, so using a rental car is convenient. To safely enjoy the depths of the forest, joining a local guided tour is recommended, and it also helps protect the endemic species. Because entry is restricted in some places in the core area of the World Heritage Site, check in advance which areas can be visited.

Practical Travel Notes

• Guided tours: Trekking and night tours are basically guide-accompanied. Because equipment, meeting places, and duration differ by tour, make an advance reservation and check the details. They may be canceled due to weather.
• Clothing and items: Because footing can become muddy, prepare comfortable shoes or trekking shoes, insect repellent, rain gear, and drinks.
• Cautions when driving: In the Yanbaru area, accidents involving rare animals such as the Okinawa rail (roadkill) are an issue. Especially at night and early morning, reduce speed and watch for animals.
• Nature protection rules: Observe manners to protect the precious nature, such as taking your trash home, not collecting flora and fauna, and not entering off the designated paths.

A Word of Advice

Yanbaru is a precious forest registered as a World Natural Heritage Site, and there are areas where entry is restricted and rules to be observed in order to protect the ecosystem.
