Jomon Sugi Yakushima 2026: 22 km Hike & Bus Guide
Jomon Sugi is the great pilgrimage of Yakushima: a gigantic, twisted Japanese cedar deep in a UNESCO-listed island ecosystem. Reaching it is not a quick sightseeing stop. The standard route is a demanding full-day trek through a historic forest railway corridor and steep mountain paths, where logistics and weather matter as much as fitness. This updated guide helps you decide whether the walk is right for you—and how to prepare without damaging the forest.
Jomon Sugi quick facts and what makes the tree special
Yakushima Town describes Jomon Sugi as about 25.3 metres tall, with a trunk circumference of 16.4 metres and an estimated age of 2,000–7,200 years. The age range is wide because the trunk is hollow and precise dating is difficult. It is a Japanese cedar (Cryptomeria japonica), not a Japanese cypress; that taxonomic mix-up still appears in some travel copy. Yakushima’s forest ecosystem is the UNESCO World Heritage property—Jomon Sugi itself is not a separate World Heritage inscription. View the tree from the designated observation platform to protect its roots.
Jomon Sugi hiking route: distance and difficulty
Arakawa trailhead to the observation deck
The local government gives a round-trip distance of about 21.2 km, with 10–12 hours required and around 1,000 metres of total elevation change. The first long section follows narrow logging railway tracks, followed by bridges, forest steps and a more strenuous woodland ascent. The forest may look gentle in photographs, but wet sleeper rails, slippery rocks and uneven stairs are real hazards. The path to Shiratani Unsuikyo Ravine can also connect to the wider trail network, but that alternative is longer and more complicated.
Historic trees along the way
The trail passes iconic forest features such as Wilson’s Stump, Daio Sugi and Meoto Sugi. They are not simply stops for selfies: these survivors tell the story of centuries of cedar logging, protection and regeneration. Allow time to look at moss, water and the understory, not only the final tree. Travelers drawn to Japan’s ancient woodlands may also enjoy the different ecosystems of Shirakami Sanchi in Aomori, Noboribetsu Primeval Forest or the volcanic woods around Aokigahara Forest, each on separate trips.
2026 Arakawa Mountain Bus: access and tickets
From March 1 to November 30, private vehicles are generally restricted on the access road to the Arakawa trailhead. The Yakushima Town visitor page says hikers use the Arakawa Mountain Bus from the Yakusugi Museum area; the published bus journey is around 35 minutes. The municipality’s listed fare is ¥1,400 round trip for junior-high-school age and above and ¥700 for elementary-school children, with conservation contributions handled separately. Times, charges and road rules can change: consult the Yakushima Town mountaineering information immediately before travel, especially for the last return service.
Where to stay and when to start
Anbo is a practical base for the museum-side bus connection, although accommodation is also available elsewhere on Yakushima. Aim to be on the trail in the early morning, normally around 5–7 a.m. depending on transport and season; check how you will get from the hotel to the shuttle before booking. Pack breakfast, lunch, water, rain protection and a headlamp. Mobile reception is inconsistent. If you have only one free day on the island and uncertain weather, plan for flexibility rather than a fixed departure.
Essential safety and low-impact hiking advice
Heavy rain is ordinary in Yakushima and can produce swollen streams, landslides or closed roads. Hire a local guide if you have limited hiking experience or want an ecological interpretation of the route. Do not start late, leave no litter and avoid stepping beyond boardwalks or observation decks. The Environment Ministry advises walkers to move in single file on railway sections, yield to working rail vehicles and take extra care on bridges with incomplete railings.

What else to do around Yakushima and southern Kyushu
Yakushima deserves more than one hike. Choose a gentler moss-forest walk at Shiratani Unsuikyo, take time for coastal scenery and local food, and arrange transport between the island’s small settlements. Travelers continuing through Kagoshima can visit Sakurajima volcano, learn about science on Tanegashima Island and at Tanegashima Space Center, or explore the broader islands on Amami Oshima. Nature lovers can also compare waterfall outings at Nachi Falls and Akame’s 48 Waterfalls, though these are far from Yakushima and not day trips.
Jomon Sugi FAQ
Can beginners hike to Jomon Sugi?
Fit beginners can sometimes complete it with careful preparation, a guide and favorable conditions, but it is a long and strenuous day rather than an easy nature walk. Be realistic about 21 kilometres, wet terrain and early transport.
Is Jomon Sugi itself UNESCO listed?
The protected Yakushima ecosystem was inscribed as World Heritage in 1993. Jomon Sugi is an extraordinary living feature within the island, not a separate UNESCO site.
Can I take a car to the Arakawa trailhead?
Not in the general March–November restriction period. Use the designated bus system or check the published exceptions and current transport notices.
