Yakushima is a subtropical island 60km off Kagoshima's coast, covered in primeval forest where Japanese cedars (杉, sugi) over 1,000 years old tower above moss-carpeted undergrowth. The island's most famous tree, Jomon Sugi, is estimated at 2,000–7,200 years old and requires a 10-hour round-trip hike to reach. The forest inspired Hayao Miyazaki's animated film Princess Mononoke.

The island receives over 4,000mm of annual rainfall ('it rains 35 days a month in Yakushima,' locals joke), creating perpetual mist and humidity that sustains the moss ecosystem and makes the forest feel otherworldly.

Insider Guide

Premium

**Jomon Sugi reality check:** The trail is serious mountain hiking — 22km round-trip with 700m elevation gain, rated as 8–10 hours (fit hikers can do 7, slow pace takes 12). The first 8km follows flat rail tracks (former logging railway), then steep ascent begins. Bring 2L+ water, lunch, rain gear (waterproof jacket + pants), and headlamp (trail starts in dark). Guides optional but recommended for first-timers (¥8,000/person). **Shiratani Unsuikyo as alternative:** This ravine trail offers ancient cedars (1,000+ years), moss-covered forest, and waterfalls in a 2–4 hour hike — perfect for visitors without time/fitness for Jomon Sugi. The Moss Forest section is where Miyazaki sketched for Princess Mononoke. Entry: ¥500. **Accommodation:** Yakushima has limited lodging (book 1 month+ ahead for high season April–October). Guesthouses in Miyanoura or Anbo towns (¥4,000–7,000/night) provide shuttle to trailheads. Mountain huts exist for multi-day hikes (reservation required).
