Cedar Avenue of Nikko

"Nikko Suginami Kaido "The Longest Tree-Lined Avenue in the World Listed in the Guinness Book of World Records

Outline "NIkko Suginami Kaido" is a street with approximately 13,300 Sugi (Japanese national tree; cedar / cryptomeria trees), which consists of three avenues, Nikko Kaido, Reiheishi Kaido and Nishiaizu Kaido with a total distance of 37km (23 miles).
Matsudaira Masatsuna, a loyal retainer serving the Tokugawas, planted more than 200,000 cedar trees in over 20 years, and at Tokugawa Ieyasu's 33rd anniversary of death he donated them to the Shinto shrine "Nikko Tosho-gu", as roadside trees.
The cedar trees stand at a height of 30 meters (98ft). Because of the length of the avenue, and the height of the trees, the Cedar Avenue of Nikko is the only cultural property designated by the Japanese Government as both a Special Historic Site and a Special Natural Monument. Additionally, it was registered in the Guinness Book of World Records as "the longest tree-lined avenue in the world" in 1991, and still was the longest in 2014. They hold some events such as "Nikko Kaido Suginamiki Festival" or "Suginamiki Marathon" too.

You will also see a rare Sugi called, "Sakura (Cherry blossom) Sugi", which there is a plethora of Sakura blossoming, on the right hand toward Utsunomiya on Nikko Kaido.
