Overview (history, characteristics, attractions)
Jomon Cedar is a giant natural Yakusugi (Japanese cedar) tree found on Yakushima Island (Yakushima Town) in Kagoshima Prefecture, and is a representative tourist attraction on the island. Since Yakushima was registered as a World Heritage Site in 1993, it has become a symbol of the island, attracting visitors from both Japan and abroad.
- Type: Yakusugi (a type of cedar)
- Estimated age: There are various theories depending on the research, but it is often estimated to be between 2,170 and 7,200 years old, and the exact age is unknown.
- Size: Tree height is approximately 25m, trunk circumference (chest height) is approximately 16m (may vary slightly depending on measurement conditions)
- Attractions: The impressive appearance that has withstood the wind and snow for many years, its harmony with the surrounding virgin forest and moss-covered forest, and the natural scenery unique to Yakushima that can be enjoyed on the round-trip hiking trail (moss, streams, boardwalks, giant trees)
Highlights
- Jomon Cedar itself: You can observe the overwhelming scale of the giant tree, as well as the expression of the trunk and the hollows (hollowed parts) up close (viewing is generally done from the observation deck).
- Forest atmosphere: Many of the hiking trails are made up of boardwalks and stairs, allowing you to experience the mossy forest floor, the scenery along the streams, and the primeval Yakusugi forest up close.
- Scenery on the way there and back: The scenery changes with the seasons and weather as the route passes through riverside sections, suspension bridges, and diverse vegetation zones (from subtropical lowlands to cool temperate highlands).
- Photo spots: The panoramic view from the Jomon Cedar Observation Deck, the wooden bridges along the way, and the moss tunnel are popular photo spots.
Access (nearest station, transportation, etc.)
Yakushima does not have a train station, so you must first travel to the mainland of Kagoshima and then take a plane or boat to Yakushima.
- Nearest base on the mainland:
- Shinkansen and conventional trains: Kagoshima-Chuo Station (Kyushu Shinkansen) - Connecting to ferry and plane from Kagoshima City
- Mainland → Yakushima:
- By plane: From Kagoshima Airport to Yakushima Airport (approximately 30-40 minutes)
- Ferry: Take a high-speed ferry from Kagoshima Port (via Kagoshima Main Port/Tarumizu, etc.) to Yakushima (Miyanoura Port or Anbo Port) (approximately 2-4 hours, depending on the ferry type)
- Travelling within Yakushima:
- Nearest trailhead: Arakawa trailhead (starting point of Jomon Cedar trekking). Local buses depart from Anbo and Miyanoura (early morning buses available for hikers).
- Taxis: Limited availability, but cost-effective for multiple people.
- Car and bicycle rentals: These are convenient for getting around the island, but please check in advance as parking at the Arakawa trailhead is limited.
- Note: Mountain buses run infrequently and tend to fill up during peak seasons, so make sure to make reservations for buses, boats, and accommodations early.
Estimated stay (estimated time required)
- Estimated time: Approximately 22km round trip, 10-12 hours in total (including breaks and photo opportunities). Time will vary depending on your stamina and walking pace.
- A day trip is common, but for those who are not confident in their physical strength or who are short on time, there are plans to stay overnight at a mountain hut (such as Arakawa Hut) and split the trip there and back (please check in advance to use the hut).
- Departure time: The standard schedule is to depart on the first bus early in the morning and return on the same day. If you depart later, there is a risk that you will not make the return bus.

Things to be aware of (crowds, manners, seasonal precautions, etc.)
- Crowds and reservations: Accommodations, boats, and buses are crowded during Golden Week, summer vacation, and the autumn foliage season. Make your accommodation and transportation reservations early.
- Equipment: Be sure to bring rain gear (tops and bottoms, waterproof jacket), non-slip trekking shoes, snacks and drinks, a mobile phone charger, and a headlamp (just in case). Yakushima receives a lot of rain throughout the year, and sudden downpours and mud can occur.
- Physical strength and time management: The round trip is a long walk, so if you are not confident in your physical strength, consider splitting your itinerary or going with a guide. Also, be sure to check the return bus schedule.
- Nature Conservation and Manners: Please observe from the designated walking paths and observation decks and do not enter restricted areas. Touching or climbing trees is strictly prohibited. Please be sure to take any trash home with you.
- Safety precautions: There may be sections along the way where there is no cell phone signal. Avoid traveling alone; travel with a group or use a guide. In bad weather, the trail may be closed or suspended.
- Seasonal considerations:
- Rainy season to autumn (typhoon season): Risk of heavy rain, flooding, and landslides. Pay attention to the latest weather information.
- Winter: Cold weather, snow and ice are possible. Anti-slip and cold weather gear are required.
- Drones/Photography: Drone flying may be subject to regulations and restrictions. Please check the local government rules before using drones.
- Cash: Some facilities and transportation on the island do not accept credit cards, so it is a good idea to bring cash with you.
Finally, Jomon Cedar is a precious natural heritage. When you visit, please keep in mind the importance of not just looking at it, but also protecting it, and make your trekking experience safe and memorable.
