Jomon sugi is famed as Japan's oldest tree and it also ranks as one of the oldest trees in the world. However, estimates range from 2200 – 7200 years old which leads to all kinds of speculation over its actual age.
Jomon sugi was 're-discovered' in 1966 by a local civil servant. It's discovery, along with other factors at the time, helped bring about the cessation of the industrial-scale logging on the island in 1970.
Although not technically challenging, the hike to Jomon sugi is a long day starting early in the morning. 10 hours is about the average time. Between March 1st to November 30th no private vehicles are allowed up to the Arakawa Trail entry point, so hikers must take the obligatory bus (1,380 yen return) .
The early part of the hike has some interesting historical features while walking along the old railway line that was built almost 100 years ago to transport lumber down to Anbo. The line is still in use and occasionally a train passes by. The railway line passes the abandoned logging village of Kosugidani. Very little remains of this village that was abandoned in 1972 almost as soon as the logging industry had stopped in this region of the island.
Although there are certainly things to see along the 8km railway line , it's not until leaving the railtrack and entering the forest that this hike comes into its element. Within 30 minutes there is the recently fallen Okina sugi (a 2,000 year old cryptomeria that fell in 2010) and then nearby is Wilson's Stump. This enormous stump is the remains of a tree probably cut down in the 1580's under the order of Toyotomi Hideyoshi. After more than 400 years of very wet conditions the stump still remains and it is so large that walking around inside is one of the highlights of this tour.
Approaching Jomon sugi there are a few gigantic trees along the way: Diao sugi being the most impressive. Gone are the days when you could hug Jomon sugi and so instead observers have to be content with viewing it from a few platforms located at different angles about 15m from the tree. In the winter you can be alone on this platform, but do not expect to be alone between March – December. In August, time at the front of the platform can be limited due to a few hundred others wanting their time to view Jomon sugi from the front of the platform.
There are plenty of places to re-fill the water containers on this trail. In the busy summer months, expect to wait up to 30 minutes to go to the washroom.
