Jōmon Sugi, standing proudly on Yakushima, a lush island designated as a UNESCO World Heritage Site in Japan, is no ordinary tree.

This ancient titan of the forest is the oldest and largest example of Cryptomeria japonica, also affectionately known as yakusugi.

Its roots reach deep into Japanese history, with estimates of its age ranging wildly from a mere 2,170 years to a staggering 7,200 years.

That’s old enough to have seen civilizations rise and fall!

The Jōmon Sugi has earned its name from the Jōmon period, a prehistoric era of Japan known for its cord-marked pottery—suggesting that this tree was already a seedling when humans were just figuring out the finer points of ceramics.

At 25.3 meters (about 83 feet) tall, with a trunk girth of 16.4 meters (54 feet), and a voluminous presence of around 300 cubic meters (close to 11,000 cubic feet), it’s not just another tree in the park—it’s the largest conifer in Japan, holding court like an arboreal emperor among lesser plants.

Located on the north face of Mount Miyanoura, Yakushima’s highest peak, getting to Jōmon Sugi is no Sunday stroll.

It requires a four-to-five-hour trek through mountain paths, which either builds anticipation or tests your patience, depending on your fitness level and fondness for hiking.

The tree’s seclusion didn’t stop it from becoming a superstar, though.

Discovered in 1968, Jōmon Sugi quickly became a symbol for conservation and a celebrity in the local tourism brochure, contributing significantly to the island’s economy.

Viewing this monumental tree, however, comes with limitations. After Yakushima was recognized as a World Heritage Site in 1993, access to the Jōmon Sugi was restricted to prevent love-struck fans (read: tourists) from getting too close.

An observation deck 15 meters away allows admirers to gaze upon its ancient bark and massive stature without the temptation of carving initials or snapping a piece of its history as a souvenir—a lesson learned after vandals took a piece of its bark in 2005.

The tree’s endurance isn’t just in its age. It’s a stoic figure, described by arborist Thomas Pakenham as a “grim titan of a tree,” rising like a rocky monument rather than a living organism, with muscular arms presiding over the surrounding young cedars and camphor trees.

In 2009, Jōmon Sugi even found a trans-Pacific partner in conservation, linking with Tāne Mahuta, a giant kauri tree in New Zealand, proving that tree diplomacy can be just as fruitful as the human kind.

So, if you’re up for a historical hike and want to meet a celebrity of the dendrological kind, Jōmon Sugi awaits. Just remember, it’s a view-only meet-and-greet; keep your hands, and any other appendages, to yourself!
