Electricity in the island is over 50 percent hydroelectric. In an experiment by Kagoshima University, it was found that hydrogen gas is also produced by using surplus power. Yakushima Island has also served as a test site for the hydrogen fuel cell vehicle research for Honda. While there are no hydrogen cars stationed in the area, the municipality of the island operates electric cars.

One of the major local attractions on the island is the Shiratani Unsuikyo Ravine. A nature park, Shiratani Unsuikyo features lush, green trees and plants. It houses various ancient cedars known to grow in the island like the Nidaiosugi, the Yayoisugi, and the Kugurisugi. It only takes about 15 minutes to walk to the most accessible yakusugi in the park. Quite popular among tourists, Shiratani Unsuikyo is the place to be in order to witness the beauty of the forests without having to take a strenuous hike.

A network of hiking trails that are well-maintained can be can be found along the ravine in the park. Suggested circuits differ in length, with some of them taking about an hour to 5 hours long to complete. Still, visitors are free to choose one’s route around the forests. There are trails that are more developed and paved in wood and stone, which are considerably easier to take in comparison to the historic footpaths that were constructed during the Edo period. English signs are available to guide visitors about the trails.

Among the primary attractions of this forest is a specific portion of its that was used as the inspiration of the animated film by Studio Ghibli entitled “Mononoke Hime,” which translates to “Princess Mononoke.” The lead artist for the movie, Oga Kazuo, spent much of his time in this part of the forest while working on sketches that were used to depict the forest as seen in the animated film. The Shirakami Sanchi Mountains located in Akita Prefecture also served as an inspiration for the mountains that were depicted in the film.

A small grove can be found on the trail going to Tsuji Toge Pass. The grove is located at the far end of the park. Walking on this trail, visitors would be led to the Jomonsugi as the trail meets the Anbo Trail, the point of which is around half the trail going to the entrance of the Okabu Trail. It takes around 12 hours when taking the roundtrip going to the Jomonsugi. The trail is also more strenuous in comparison to the trail that begins at the Arakawa Trailhead.

The other major local attraction of the island is the Jomonsugi. A giant cedar tree, scientists estimate the age of the tree to be around 2,000 to 7,200 years old. Some say that this tree is the oldest tree in the country, as it has been standing since the Jomon period, where its name was based on. Though the tree is not exactly the tallest in the country with the height of 25 meters, its trunk is huge with a diameter of 5 meters.

A theory suggests that the Jomonsugi was first found by loggers from the Edo period hundreds of years ago. Some say that due to its irregular shape, the tree was able to avoid logging. The tree was rediscovered in the 1960s. Since then, the Jomonsugi has been under protection, together with the rest of the forests in Yakushima Island, as they have become a national park.

Other well-known trees in the area stand along the trail going to the Jomonsugi. These trees include the Meotosugi, the Daiosugi, and Wilson’s Stump. The Meotosugi is composed of a pair of trees that look like two people embracing each other. Literally translating to “Great King Cedar,” the Daiosugi is one of the biggest trees located in Yakushima. The Wilson’s Stump is composed of the hollowed out remains of a huge cedar that felled almost 300 years prior.

Aside from the two main attractions mentioned above, there are other places to check out in Yakushima. One of these places is Yakusugi Land. Also a nature park, the land is filled with yakusugi, which are Yakushima Cedars that are more 1,000 years old. These include the Buddhasugi, the Sennensugi, and the Futagosugi. A series of trails that are well-developed can also be found in the area, which leads visitors to the said trees. This nature park is among the places in the island that is most accessible if one is searching for ancient cedar trees.

Hikers, whether beginners or experts, can choose from a wide range of hiking courses in the park. The courses available differ in length; some of them can be completed in a span of just 30 minutes while others can be completed in two and a half hours. All the trails follow a single route that leads into the park but each route has different turnoff points. Nonetheless, these would all still lead back to the trailhead.

A boardwalk trail is followed by the shortest hiking course available in this area, with the trail leading to the yakusugi. However, the more strenuous hiking courses actually lead further into the forest over different kinds of trails. The longest hiking course available leads hikers to the peak of Tachudake. English signs can be found throughout the park to guide hikers while English pamphlets can also be obtained at the trailhead.

Driving from Yakusugi Land, visitors can further drive into the mountains for 15 minutes and reach another one of the giant cedars in Yakushima known as the Kigensugi. Situated just next to the road, this ancient tree is the only giant cedar in Yakushima that can be reached by car.
