Jomonsugi

What to know

Jomonsugi (縄文杉, Jōmonsugi) is Yakushima's star attraction—a colossal cedar tree estimated to be between 2,000 and 7,200 years old. Believed to be Japan's oldest tree, it dates back to the Jomon Period, which inspired its name. Though only about 25 meters tall, its trunk measures roughly 5 meters in diameter, giving it an imposing presence.

The tree was likely first discovered centuries ago by Edo Period loggers. Like other ancient cedars on Yakushima, it was spared from logging due to its irregular shape. Rediscovered in the 1960s, Jomonsugi has since been protected as part of Yakushima's national park forests.

Along the trail to Jomonsugi, you'll encounter other famous trees: Meotosugi, a pair of trees resembling an embracing couple; Daiosugi (Great King Cedar), one of the island's largest; and Wilson's Stump, the hollow remains of a giant cedar felled three centuries ago.

The round-trip hike takes about ten hours, so start before dawn to finish by sunset. The first section on the Anbo Trail follows a seldom-used railway—flat and relatively easy. The second part on the Okabu Trail mixes dirt paths, boardwalks, and wooden steps, often steep.

For a more relaxed pace, stay overnight at Takatsuka Hut, about 200 meters past Jomonsugi. The larger Shin-Takatsuka Hut is about one kilometer further along the Miyanoura Trail. Neither hut is staffed. Overnight camping is allowed only at the huts and designated tent areas nearby.

Proper gear is essential: good rain gear and hiking boots are highly recommended. Bring your own food, toiletries, and plenty of water. Toilets and water are available at the trailhead, the entrance to Okabu Trail, and near Jomonsugi (toilets at Takatsuka Hut, water at the steps before the tree).
