Nikko Suginamiki Kaido (Nikko Cedar Avenue)
日光杉並木街道
Stretching over 35 kilometers, Nikko Suginamiki Kaido is the longest tree-lined road in the world. The towering cedar trees on both sides of the path were originally planted in the Edo period to provide a suitably regal approach to Nikko Toshogu Shrine. Around 200,000 were planted over a 20-year period, and today some 12,500 remain.
