Jōmon Sugi (縄文杉) is a large cryptomeria tree (yakusugi) located on Yakushima, a UNESCO World Heritage Site, in Japan. It is the oldest and largest of nearly 2,000-year-old-growth cryptomeria trees on the island,[2] and is estimated to be between 2,170[3] and 7,200 years old.[4][5][6][7] Other estimates of the tree's age include "at least 5,000 years",[8] "more than 6,000 years",[9] and "up to 7,000 years old".[2] The tree's name is a reference to the Jōmon period of Japanese prehistory.[10]
