The basic information about the discs of Yaku-sugi, old Cryptomeria japonica more than 1,000 years old on Yakushima Island in Japan, has been collected and 88 discs (54 individual trees) are displayed as Yaku-sugi discs in Japan. By checking the tree rings on the discs, 54 discs (23 individual trees) are identified as the Yaku-sugi disc on which the tree rings are recognized to total more than 1,000. The highest number of the tree rings on the disc is about 2,000.
