Yanbaru Forest

Northern Okinawa above Nago is where the island reverts to something it must have been before human settlement took hold — dense subtropical forest climbing hills that roll down to a coastline of small bays and hidden beaches. Yanbaru is the Japanese name for this region, which became Japan’s newest national park in 2021, and the designation acknowledged what had been de facto true for a long time: this forest doesn’t need managing so much as it needs leaving alone. The Okinawa rail, a flightless bird found nowhere else on earth, lives here. So does the Okinawa woodpecker, the Ryukyu long-furred rat, and dozens of other endemic species protected by the sheer difficulty of the terrain.

I drove north from Nago on Route 58, which hugs the western coast before climbing into the hills above the village of Oku, the northernmost settlement accessible by road. The Hiji Waterfall trail was the first walk I did — forty minutes through forest so dense that at noon the canopy filtered the light to something green and cathedral-like, the kind of green you find in old-growth places where the light has been negotiating with leaves for a very long time. The waterfall at the end is a thirty-metre cascade into a cold clear pool. I swam in it and ate the onigiri I’d bought at a convenience store at six in the morning and thought I’d been trying too hard everywhere else.

The Yanbaru Learning Forest, operated near Kunigami village, runs guided night walks to find the Okinawa rail. The bird is more audible than visible — a series of urgent, reedy calls from the undergrowth that the guides can identify and locate, and occasionally, in the beam of a red-filtered torch, a stocky brown shape moving quickly between leaf litter. The guides speak quietly, move slowly, and know exactly which patches of forest the rails prefer. My guide had been doing this for fifteen years and could identify the bird’s call the way a musician identifies an instrument by its overtones.

The coast along Yanbaru’s edge has none of the tourist infrastructure of the central or southern island. Aha Beach, near the cape, is a small bay of clear water where I was the only person for an entire afternoon. The road to reach it is one lane and seems to require the car to make decisions the map hasn’t accounted for.

When to go: November through April for the best wildlife conditions and manageable temperatures. The Okinawa rail is most active at dusk and dawn year-round, but the cool season makes the forest walks significantly more comfortable. Summer is hot and humid, though the forest canopy provides real relief; typhoons in September can close trails temporarily.
