Yakushima is a World Heritage site where untouched nature still thrives. Deep within its forests, Jomon Sugi has stood through the ages, captivating countless travelers as a truly special presence. Trekking to see this tree, said to be several thousand years old, up close is a breathtaking experience that belongs on everyone’s once-in-a-lifetime list. As of 2026, the most common ways to reach Yakushima are by ferry or plane from Kagoshima, while a dedicated shuttle bus is used to access the Arakawa Trailhead, the main starting point for the trek to Jomon Sugi. The approximately 10-hour round trip is by no means easy, but with the right preparation and mindset, it can become an unforgettable memory. In this guide, the OlaChill editorial team provides domestic travelers planning a Jomon Sugi trek from the Arakawa Trailhead with all the essential information and useful tips they need.
The Appeal and Basic Information of the Jomon Sugi Trek
Jomon Sugi, the symbol of Yakushima, is one of Japan’s most impressive giant trees, with an estimated age of 2,000 to 7,200 years. Its overwhelming presence and the mysterious, moss-covered forest surrounding it transport visitors back to a primeval world. Trekking to Jomon Sugi is far more than simply walking through the mountains—it is a one-of-a-kind experience that lets you feel Yakushima’s rich nature, history, and the power of life with your entire body.
Hours / Fees / Access (Nearest Station・Travel Time)
The Jomon Sugi trekking route itself does not have “opening hours,” but access to the Arakawa Trailhead is heavily dependent on the shuttle bus operating schedule. Shuttle buses normally run from March 1 to November 30, and ordinary vehicles are restricted from entering during this period. In winter (from December 1 through the end of February), ordinary vehicles may use the road, but it may be closed depending on snow conditions, so caution is necessary.
Use of the trekking route is basically free, but visitors are encouraged to voluntarily contribute to the “Yakushima Mountain Entry Cooperation Fee” to help protect the island’s natural environment. The suggested contribution is 1,000円 per person for a day hike and 2,000円 per person for an overnight stay in the mountains, collected before the Arakawa Trailhead. These contributions are used for environmental conservation and trail maintenance.
To reach the Arakawa Trailhead, first travel from Yakushima’s main settlements, such as Miyanoura and Anbo, to the Yakusugi Museum by bus or rental car. From the parking lot at the Yakusugi Museum, you must transfer to the paid shuttle bus bound for the Arakawa Trailhead. Shuttle bus operating times vary by season, but the first buses begin running from around 5:00 a.m., with the last buses operating until the evening. The shuttle bus fare is 700円 one way per adult, or 1,400円 round trip (as of 2026). We strongly recommend checking the latest schedule and fares on the official Yakushima Kotsu website.
Complete Guide to Accessing the Arakawa Trailhead
The Arakawa Trailhead, the gateway to the Jomon Sugi trek, is located at an elevation of approximately 600m, and the one-way distance from there to Jomon Sugi is about 10km. Most of the journey to the trailhead is made by shuttle bus, which was introduced to help protect Yakushima’s natural environment.
Getting to Yakushima The main ways to reach Yakushima are as follows.
- By plane: Approximately 35 minutes from Kagoshima Airport to Yakushima Airport. Although there are relatively few flights, this is the fastest option.
- By ferry: Approximately 2 hours from Kagoshima New Port to Miyanoura Port or Anbo Port by high-speed ferry (Toppy・Rocket), or approximately 4 hours by Ferry Yakushima 2. If you have plenty of time, the boat journey is also highly recommended.
From the Island to the Arakawa Trailhead After arriving on Yakushima, follow these steps to reach the Arakawa Trailhead.
- Travel to the Yakusugi Museum:
- Local bus: Local buses to the Yakusugi Museum operate from Yakushima Airport, Miyanoura Port, and Anbo Port. For example, the journey from Anbo Port to the Yakusugi Museum takes approximately 20 minutes.
- Rental car: You can also drive to the Yakusugi Museum by rental car. The museum has a free parking lot. However, during the shuttle bus operating period, ordinary vehicles are restricted from traveling beyond this point.
- Transfer to the Arakawa Trailhead shuttle bus: Take the dedicated shuttle bus to the Arakawa Trailhead from the parking lot at the Yakusugi Museum. You must purchase a bus ticket in advance. Tickets can be bought at Yakushima Kotsu offices, hotels, or the Yakusugi Museum. The journey from the Yakusugi Museum to the Arakawa Trailhead takes approximately 30 minutes. Since the shuttle buses begin operating early in the morning, plan to arrive at the Yakusugi Museum in time for the first departure. Buses may be full during particularly busy periods, so it is important to allow plenty of time.
Jomon Sugi Trekking Clothing and Gear: Seasonal Tips
The Jomon Sugi route is a long trek lasting approximately 10 hours, so wearing suitable clothing and carrying the right equipment are essential for a safe and comfortable hike. Yakushima’s weather changes so quickly that the island is said to receive “35 days of rain in a month,” making rain gear indispensable.
Basic Clothing and Gear
- Hiking boots: Waterproof, mid-cut or higher hiking boots with excellent grip are essential. They protect your ankles and reduce the risk of slipping on muddy trails.
- Rainwear: A two-piece rain suit made from a waterproof, breathable material such as Gore-Tex is ideal. Yakushima’s rain can be intense, and rainwear also helps protect you from the cold.
- Backpack: A pack with a capacity of approximately 20～30L and a rain cover is recommended.
- Trail snacks: Bring easy-to-eat sources of energy, such as onigiri, bread, chocolate, and jelly drinks.
- Drinking water: Bring approximately 1.5～2L. There are water sources along the route, but you may also want to carry a water purifier.
- Headlamp: Essential for safety when setting out early or returning near sunset.
- Warm clothing: Bring a fleece or lightweight down jacket for rest breaks and worsening weather.
- Towels and spare clothes: Choose quick-drying items in case you sweat or get wet in the rain.
- Other items: A map, compass, mobile phone, portable battery, first-aid kit, bear bell, and more.
Seasonal Tips
- Spring (March～May): The fresh greenery is beautiful, and temperatures are generally comfortable. Mornings and evenings can be chilly, so a lightweight warm layer is necessary. On some days, short sleeves may be comfortable while trekking, but be fully prepared for wind and rain. The trail is extremely crowded during Golden Week.
- Summer (June～August): This is a hot and humid season when you will sweat easily. Wear quick-drying clothing and make sure to hydrate frequently. Since it is also typhoon season, checking the weather forecast is essential. Do not forget insect repellent.
- Autumn (September～November): Temperatures begin to fall, and it is a good season for enjoying the autumn foliage. Conditions are relatively comfortable, as in spring, but be careful of chilly mornings and evenings. This period is also relatively busy.
- Winter (December～February): Snow and icy conditions are possible around Jomon Sugi, which is at a high elevation. Winter mountain gear such as crampons and an ice axe may be required, making this a season for experienced hikers. Protection from the cold is the top priority, and a thick down jacket plus highly waterproof and windproof outerwear are essential. Since the shuttle bus does not operate, you must also check transportation options to the Arakawa Trailhead in advance.
