Ancient cedar trees thousands of years old, cloud-shrouded mountain peaks, and crystal rivers — Yakushima is a UNESCO World Heritage wilderness unlike anywhere else. Here's how to plan your visit.
About Yakushima
Yakushima is a roughly circular island approximately 130km in circumference, located 60km south of Kagoshima. Its interior rises dramatically to Miyanoura-dake (1,936m), the highest peak in Kyushu, and the island receives up to 10,000mm of annual rainfall in its mountain core — making it one of the wettest places on Earth and producing a forest of extraordinary density and antiquity. The UNESCO World Heritage designation in 1993 protects the island's interior, where Yakusugi cedars (Cryptomeria japonica) of over 1,000 years grow in groves that feel genuinely prehistoric.
Yakushima is the island believed to have inspired the setting of Studio Ghibli's Princess Mononoke. Walking through the Shiratani Unsuikyo ravine — its mossy boulders and twisted ancient trees exactly matching Miyazaki's hand-painted backgrounds — the comparison becomes immediately obvious. The island also has a permanent population of Yakushima macaques and sika deer habituated to humans, often seen grazing roadside with complete indifference to observers.
Top Trails
Jomon Sugi Trail is the island's most famous hike — a 22km return journey to the Jomon Cedar, a tree estimated to be between 2,170 and 7,200 years old. The trail begins at Arakawa trailhead (accessed by shuttle bus from Yakusugi Land, 4am–5am departures in high season) and takes 8–10 hours return. The path passes through dense sugi forest, crosses wooden boardwalks over ravines, and climbs steadily before revealing the enormous, gnarled trunk of Jomon Cedar — larger and more otherworldly than photographs suggest. Start early, carry rain gear, and bring sufficient food and water; there are no facilities on the trail.
Shiratani Unsuikyo Ravine is more accessible — a 3–4 hour loop through the island's most cinematic moss-forest landscape. Multiple trail options cater to different fitness levels, from an easy 40-minute valley walk to a full traverse connecting to the Jomon Sugi trail. The moss glows electric green in rain and morning light; visiting during light drizzle is actively recommended.
Miyanoura-dake Summit is the island's ultimate challenge — a 12-hour return hike to the highest peak in Kyushu, requiring one night at the mountain hut (Ishizuka Hut, book in advance). The views from the summit across the Pacific, with the island's other peaks below, are extraordinary on clear days.
When to Visit
Yakushima can be visited year-round, but each season has distinct character. March to May brings mild temperatures, spring wildflowers on the upper peaks, and acceptable rain levels. June and July (tsuyu) see the highest rainfall — the moss forest is at its most intense and otherworldly, but be prepared for wet conditions. August to October is the peak visitor season — clearer skies, higher temperatures, and busy trails. November to February offers quieter trails and the possibility of snow on the upper peaks, but some mountain huts close and ferry schedules reduce.
Getting to Yakushima
- Ferry from Kagoshima: The Toppy high-speed ferry takes approximately 2 hours and is the most common access route. Book ahead in high season — it sells out. Check current fares on the Tanegashima/Yakushima Koku website.
- Slow ferry: The cargo-passenger ferry (Yakushima Ferry) takes around 4 hours but is significantly cheaper than the high-speed option and has reclining seats. A good choice if you're not in a hurry.
- Flight from Kagoshima: Around 35 minutes. Useful if ferries are booked out, but baggage limits are strict on the small propeller aircraft.
Practical Tips
- Rain gear: Non-negotiable. Pack a quality waterproof jacket and trousers regardless of the forecast. The weather changes within minutes.
- Trailhead shuttles: Private cars cannot access Arakawa trailhead during peak season (March–November). Shuttle buses run from Yakusugi Land from around 4am. Get there early or you'll miss the first buses.
- Yakusugi Museum and Yakusugi Land: Both worth a half-day visit to understand the island's ecology and see ancient cedar specimens without the full-day commitment of the Jomon Sugi hike.
- Accommodation: Book accommodation in Miyanoura (the main port town) or Anbo well in advance. Options are limited and demand is high from April through October.
- Access fee: A voluntary conservation fee (Yakushima Kankyou Bunka Mura) is requested on arrival — pay it. The island's preservation depends on visitor contributions. Check the current amount before travelling.

Final Thoughts
Kyushu is the Japan that many travellers dream of but rarely find: authentic, unhurried, breathtakingly beautiful, and utterly original. It's a place where ancient traditions live comfortably alongside modern Japan, where you can soak in a private forest rotenburo at dawn and eat exceptional ramen from a street stall at midnight.
