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 among the old-growth cryptomeria trees on the island, and is estimated to be between 2,170 and 7,200 years old. Other estimates of the tree's age include "at least 5,000 years", "more than 6,000 years", and "up to 7,000 years old". The tree's name is a reference to the Jōmon period of Japanese prehistory. In 2005, vandals stripped from the tree a piece of bark measuring about 10 cm (4 in) on each side.
