Yakushima’s cedar forests and granite mountains
Published on 09/14/2026 at 09:47 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
Yakushima is a mountainous island south of Kyushu, known for its granite peaks, deep forest and stands of ancient cedar. Its World Heritage area was inscribed in 1993, and the island’s wooded slopes rise through a striking vertical spread of vegetation.
Granite slopes and cedar forest
The island is built around a mountainous core, with a temperate rainforest extending from the centre towards the coast. UNESCO describes it as almost round-shaped, and the same source places it about 60 km south of Kyushu’s southern tip.
The forest is closely tied to Japanese cedar, or sugi, including old trees known locally as yakusugi. The Japanese Ministry of the Environment says the island has cedars more than 1,000 years old and a vegetation zone that runs from sea level to the mountain tops.
The world heritage landscape
Yakushima became a World Natural Heritage site in 1993, and the inscribed area covers 10,747 ha. The UNESCO biosphere reserve now extends across the whole island and includes the surrounding marine area.
That status reflects the combination of forest, mountain terrain and coastal setting rather than a single monument. The island’s landscape is shaped by steep relief, heavy rain and granite, with the old cedar forests concentrated in the interior.
Jomon Sugi and the island’s oldest trees
The island is closely associated with Jomon Sugi, the giant cedar tree that has become its best-known landmark. Japan Travel identifies it as one of the oldest trees on the island, with an estimated age of between 2,000 and 7,200 years.
The same source gives its height as 25.3 m (83 ft) and its circumference as 16.4 m (54 ft). Those figures make the tree part of the island’s identity, but the wider impression comes from the forest around it, where other cedars also reach advanced age.
Visiting Yakushima: what travellers from Western Europe should know
- The island lies in Kagoshima Prefecture, south of Kyushu. Ferries and flights connect it with the mainland, and the names of the main access points vary by route.
- The terrain is mountainous, with forested slopes and long walks on marked trails through cedar country. Jomon Sugi is reached on foot, and the approach runs through inland mountain country.
- The official language is Japanese and the currency is the Japanese yen.
- Yakushima sits in a humid oceanic setting with forest from coast to summit. That makes the island’s vegetation and mountain views central to any visit.
