The Jomon Sugi trail is the reason most visitors make the long journey to Yakushima Island. At the end of a 22-kilometer round trip through ancient cedar forest, a single tree waits — one estimated to be between 2,170 and 7,200 years old, making it potentially the oldest living thing in Japan and one of the oldest on Earth. No photograph prepares you for the moment you round the final bend and encounter it in person. The Jomon Sugi is enormous, otherworldly, and profoundly moving. This guide covers everything you need to know to hike it safely and successfully.
The trail demands a full day — most hikers take 8 to 10 hours for the round trip — and should not be underestimated. The route is long rather than technically demanding, but wet conditions, slippery roots, and sheer duration catch many unprepared hikers off-guard. With proper preparation, the Jomon Sugi hike is achievable for most reasonably fit adults and rewards every calorie of effort. This Jomon Sugi hiking guide covers trailhead access, trail conditions by season, gear requirements, guided tour options, and the best tips for first-time hikers.

What Is the Jomon Sugi?
Age and Significance
Jomon Sugi (縄文杉) — literally “Jomon cedar” — takes its name from the Jomon period of Japanese prehistory (approximately 14,000 BCE to 300 BCE), during which Japan’s earliest known culture flourished. The tree is named for this era because its age estimates place its germination during or before that period. The range of 2,170 to 7,200 years exists because two different dating methods produce different results: outer ring analysis of a fallen nearby tree suggests the lower figure, while estimation from the Jomon Sugi’s girth and growth rate patterns supports the higher figure. Most scientists consider 2,170 years the conservative minimum, while the possibility of 7,200 years cannot be ruled out.
The tree stands 25.3 meters tall, with a girth of 16.4 meters at its base — so wide that a group of eight adults with arms outstretched cannot encircle it. Its trunk is dramatically irregular, with enormous buttress roots and burls that give it the appearance of a creature from a Miyazaki film rather than a living plant. A viewing platform was constructed at a respectful distance to protect the root system from compaction, meaning visitors observe from roughly 10 meters away rather than touching the bark. This restriction is the right call ecologically, even if it frustrates the impulse to make contact with something so ancient.
Yakusugi vs. Ko-sugi
Not all ancient-looking trees on Yakushima are technically “yakusugi.” The designation applies specifically to Japanese cedars (cryptomeria japonica) rooted in Yakushima’s mountains that are over 1,000 years old. Trees between 100 and 1,000 years old are called “ko-sugi” (young cedar), though even these are impressive by any normal standard. The Jomon Sugi is the oldest and most famous yakusugi, but the trail to it passes dozens of other magnificent specimens, making the journey as rewarding as the destination.
Top Sections of the Jomon Sugi Trail
Arakawa Trailhead to Kogen-cho (0–3.5km)
The hike begins at Arakawa Trailhead, accessible only by permit-controlled shuttle bus during peak season (March through November) and by private car in the off-season. The shuttle departs from Yakusugi Museum parking area starting at approximately 5:30 AM and costs around 1,600 yen round trip. The first 3.5 kilometers follow a disused forest railway track, passing through a cedar tunnel that becomes progressively more atmospheric as mist rises from the valley floor. The railway ties underfoot are sometimes slippery — move carefully even in dry conditions.
Kogen-cho to Wilson Stump (3.5–4.5km)
The trail leaves the railway tracks and begins its ascent through living forest. At kilometer 4.5, a short side path leads to the Wilson Stump — the massive hollow base of a cedar felled in 1586 on the orders of Toyotomi Hideyoshi, who needed timber for the construction of a Kyoto temple. The stump’s interior is large enough to shelter a dozen people, and looking straight up from the center reveals a view framed by the weathered wood that appears, from the right angle, to form a heart shape. This has become one of Yakushima’s most photographed moments. The Wilson Stump itself is approximately 13.8 meters in circumference.
Wilson Stump to Daio-sugi (4.5–7.5km)
Above the Wilson Stump, the trail becomes steeper and the cedars increasingly ancient. Several named trees dot this section, including Meoto-sugi (Husband and Wife Cedars) — two massive trees whose canopies have grown together overhead — and Daio-sugi (Great King Cedar), an imposing 3,000-year-old specimen visible from the trail. This section is the most demanding of the hike in terms of sustained elevation gain, climbing approximately 300 meters over 3 kilometers. Take your time, drink regularly, and eat a snack at Daio-sugi before the final push.
Daio-sugi to Jomon Sugi (7.5–11km)
The final section to the Jomon Sugi traverses ridgeline forest with occasional views down through the canopy into mist-filled valleys. The last kilometer includes some of the most dramatic forest scenery of the entire route before the trail opens onto the viewing platform. The Jomon Sugi itself stands at approximately 1,300 meters elevation. Most hikers spend 15 to 30 minutes at the platform, taking photographs and absorbing the experience. On weekdays and in shoulder season, the platform is often uncrowded enough for quiet contemplation. On spring and autumn weekends, arrive by 9 AM to avoid significant queues at the viewing area.
How to Book the Jomon Sugi Hike
Guided Tour Options via Klook
A guided Jomon Sugi day hike is the recommended choice for most first-time visitors. Guides provide ecological commentary, navigate the occasional unmarked fork, manage group pace to ensure completion before dark, and handle shuttle bus logistics. English-speaking licensed Yakushima nature guides charge approximately 15,000 to 25,000 yen per person for a full-day Jomon Sugi tour including shuttle bus transfer, packed lunch, and waterproof gear recommendations. Group sizes are typically capped at 6–8 participants. Book at least 2 weeks in advance for peak season (late March to May, and October). Browse Jomon Sugi guided hikes on Klook →
Self-Guided Hiking Permits and Access
Self-guided hiking is permitted on the Jomon Sugi trail. During peak season, private vehicles are banned from the Arakawa access road, so all hikers must use the permit shuttle bus system. Permits for the shuttle are distributed at Yakusugi Museum parking area each morning on a first-come basis; arrive by 4:30–5:00 AM to guarantee a spot on early shuttles. Off-peak (December through February), private car access to Arakawa Trailhead is permitted, though winter conditions require additional preparation and the trail may be partially icy.
Finding Accommodation Near the Trailhead
The town of Anbo on Yakushima’s eastern coast is the closest accommodation hub to the Arakawa Trailhead shuttle departure point, reducing your pre-dawn commute to minutes rather than an hour of driving. Guesthouses in Anbo typically start around 7,000 to 9,000 yen per person per night with breakfast. For early starts, request your accommodation to prepare an early bento box for your hiking lunch.

Tips for Completing the Hike Successfully
Essential Gear List
Waterproof jacket and pants are non-negotiable — even on blue-sky mornings, afternoon rain is common in the mountains. Waterproof hiking boots with ankle support are strongly recommended; trail runners are manageable but sneakers should not be worn on the Jomon Sugi trail. Trekking poles dramatically reduce strain on knees and improve stability on wet root sections. Pack at minimum 2 liters of water; a filter bottle or purification tablets allow you to refill from the numerous mountain streams. A headlamp with fresh batteries is essential for early starters who hit the trail in darkness, and for anyone whose pace runs long into the afternoon. Bring a packed lunch and enough snacks for 10 hours — there are no food or drink vendors anywhere on the trail.
Starting Time and Pacing
The single most important factor in a successful Jomon Sugi hike is starting time. Most guides recommend being at the Arakawa Trailhead by 6:30–7:00 AM at the latest. Starting at 5:30–6:00 AM is better still, giving buffer time for photos, rest breaks, and the unpredictable delays that a wet trail can introduce. A typical pace: trailhead to Jomon Sugi in approximately 4.5–5 hours, 45 minutes at the viewing platform, and 3.5–4 hours back to the trailhead. The last shuttle bus back to the museum parking area departs Arakawa at around 5:00–6:00 PM depending on season; confirm the exact time before departing.
Altitude and Physical Preparation
The Jomon Sugi hike reaches approximately 1,300 meters elevation, which is modest by alpine standards but noteworthy for visitors arriving from sea-level Kagoshima. The elevation gain of approximately 600 meters is spread over 11 kilometers (one way), making the gradient gentle rather than steep. Most adults who exercise regularly can complete the hike. If you have doubts about your fitness level, the guided tour option is particularly valuable — guides can adjust pace and provide encouragement throughout the day. Train with walks of 3–4 hours in the weeks before your trip.
Respect the Forest
The Jomon Sugi trail passes through one of the world’s most ecologically significant forests. Hike only on the marked path — stepping off trail compacts the soil around root systems and destroys the mosses and liverworts that make Yakushima’s forest floor extraordinary. Pack out all rubbish. Do not touch the Jomon Sugi or the fencing around other named trees. The mountain stream water looks pristine but should be filtered or purified before drinking. Observing these simple rules helps ensure that the Jomon Sugi remains healthy for the next 7,000 years.
Frequently Asked Questions
How difficult is the Jomon Sugi hike?
It is graded as moderate by Japanese standards — long (22km, 8–10 hours) rather than technically difficult. The main challenges are duration, wet trail surfaces, and some slippery root sections. Proper waterproof footwear and an early start solve most problems. Most fit adults in reasonable health can complete it.
Can I hike the Jomon Sugi without a guide?
Yes, guides are not legally required. However, the trail has unmarked forks and the consequences of getting lost or injured far from trailhead are serious. For first-time visitors, a licensed guide adds safety, ecology knowledge, and significantly enriches the experience.
What shuttle bus do I need to take?
During peak season (March–November), the Arakawa Mountain Eco-shuttle departs from Yakusugi Museum parking area starting at approximately 5:30 AM. Cost is approximately 1,600 yen round trip. Spots are first-come, first-served at the parking area. Your accommodation can provide current season schedules.
How much does the Jomon Sugi hike cost?
Self-guided: approximately 1,600 yen for the shuttle bus. Guided: 15,000–25,000 yen per person including shuttle, guide fees, and typically a packed lunch. Gear rental if needed adds approximately 2,000–4,000 yen for poles and rain gear.
Is the trail closed in winter?
The trail is not officially closed in winter, but snow and ice conditions above 1,000 meters make it dangerous without crampons and alpine experience. December through February sees very few hikers on the full Jomon Sugi route. Self-guided off-season hiking is not recommended for those without mountain experience.
Is the Jomon Sugi really 7,200 years old?
The upper age estimate of 7,200 years comes from ring-based growth rate calculations rather than direct ring counting (which is not possible without cutting the tree). The conservative scientific estimate is approximately 2,170 years, based on comparison with nearby fallen trees. The actual age is somewhere in this range — either figure makes it among the most ancient trees on Earth.

Day-Before Checklist
The evening before your hike, run through this checklist to maximize your chances of a smooth experience. Confirm the shuttle bus schedule with your accommodation and set two alarms for a 4:30–5:00 AM wake-up. Fill your water bottles and prepare your snacks and packed lunch. Charge your phone and camera fully. Check the weather forecast for the mountain zone — light rain is normal and manageable; heavy sustained rain or typhoon warnings warrant a postponement decision. Lay out all your gear so nothing is forgotten in the pre-dawn rush. If you have trekking pole rentals booked, collect them the night before. Finally, tell your accommodation host your planned start and return time so they can raise an alarm if you are overdue.
