At 37 kilometers long, Cedar Avenue is officially the longest tree-line avenue in the world. While there were originally 200,000 trees planted in a 20-year span from 1625, today the number of surviving trees number around 13,000 due to construction and exhaust damage from cars. About 100 trees a year continue to fall down, but preservation and prevention measures are in place.
One of the more popular hikes along the trail include the “Ekikara Hiking” trip, where you can walk from Imaichi station to some of the local shrines, stop over at a local sake brewery and take a breather at the Suginamiki Park (Cedar Tree Park). It's a great place to visit particularly during spring, but I would recommend that those with strong pollen allergies avoid the area and perhaps visit at the end of summer.
