UNESCO-listed rain-soaked island of ancient cedars, mossy forests and mountain trails
Yakushima rises steeply from the sea south of Kyushu, its granite peaks reaching nearly 2,000 metres. Moist ocean air meets the mountains here, and the island is famously wet: locals joke that it rains 35 days a month. That rain feeds an extraordinary forest of mosses, ferns and giant cedars known as Yakusugi, some of them more than 1,000 years old.
The best-known walks lead through the Shiratani Unsuikyo Ravine, whose mossy boulders and ancient trees inspired the artists behind the film Princess Mononoke, and up to the Jomon Sugi, a huge cedar deep in the mountains reached on a long day's hike. Along the way you may meet the island's own subspecies of deer and macaques. Waterfalls, hot springs and quiet coastal villages complete an island that rewards travellers who come prepared for the weather.
For centuries Yakushima's people lived from fishing and farming on the coast, while the mountains were regarded as sacred. Yakusugi cedar was long harvested for timber, and logging railways were built into the forest; parts of these tracks are still followed by the trail to the Jomon Sugi. The great cedar itself was found in 1966 at about 1,350 metres.
On 11 December 1993, Yakushima became one of Japan's first World Natural Heritage sites, together with Shirakami-Sanchi. The inscribed area, about 10,747 ha or roughly a fifth of the island, protects a forest UNESCO describes as a rare remnant of warm-temperate forest, with vegetation arranged in distinct bands from subtropical coast to high moorland.
Island life follows the rhythm of rain, sea and mountains. Fishing villages ring the coast, and the island's forests are both a source of pride and a long-standing responsibility: residents, guides and the Ministry of the Environment work to protect the World Heritage area while welcoming hikers. Local guides are a big part of the community. Respect for the mountains, once seen as home to the gods, still shapes the island's attitude to nature.
Choose a walk to suit your fitness. Shiratani Unsuikyo offers marked trails from about an hour up to five hours, including the moss forest and the climb to the Taiko Iwa rock for views over the interior. Fit hikers can tackle the Jomon Sugi trail from the Arakawa trailhead, a long day of about 19 km round trip that follows old railway tracks before climbing through the forest. Submit a climbing registration form and consider an experienced guide, some of whom lead hikes in English.
On easier days, drive the coastal road to see waterfalls such as Senpiro Falls, soak in a seaside hot spring, and watch for macaques and deer along the roads. The Yakusugi Museum, where the Arakawa shuttle bus starts, is a good introduction to the island's cedars.
Spring (March to May) and autumn (October to November) are generally the best seasons for hiking, according to JNTO. Summer is hot and humid, and the rainy season (typically May to June) and typhoon season (late summer to early autumn) can bring heavy rain and transport disruption. Winter brings snow to the high trails. Rain is possible on any day of the year, so a flexible itinerary helps.

Miyanoura, the main port, and Anbo on the east coast have most of the island's accommodation, shops and restaurants, and are the departure points for buses and shuttles to the trailheads. Yakushima Airport lies on the north-east coast between them. Kagoshima city on Kyushu is the usual gateway, with boats from its port and flights from Kagoshima Airport, more than an hour from the ferry terminals.
Shuri Castle was the political and cultural heart of the Ryukyu Kingdom for about 450 years. Its main hall is being rebuilt after the 2019 fire, while Naha below offers markets, pottery and island food.
