In dry air conditions, the initial density of Japanese cedar timber has been determined to be about 300–420 kg/m 3. [14] It displays a Young's modulus of 8017 MPa, 753 MPa and 275 MPa in the longitudinal, radial and tangential direction in relation to the wood fibers.
In general, the Japanese cedar lives for about 500 years, but yakusugi trees live much longer. They grow on less nutritious granite soil slowly and have a very tight grain. The wood contains a lot of resin due to Yakushima's high rainfall and high humidity, making it resistant to rotting. As a result, these trees tend to have longer lives, and ...
Cryptomeria stamens and pollen. Hay fever in Japan (花粉症, kafunshō, "pollen illness") is most commonly caused by pollen from Cryptomeria japonica (known as sugi in Japanese and often translated as "cedar" though it is not a member of the Cedrus genus) and Japanese cypress (known as hinoki), two native Japanese tree species.
Daisugi (台杉) is a Japanese technique related to pollarding, used on Cryptomeria (sugi) trees. [1] [2] [3] The term roughly translates to "platform cedar". [4] When applied in a silviculture context, the daisugi method requires trunks to be pruned every 2–4 years in order to maintain the straight, clear grain that they are coveted for. [5] [6]
Sugi no Osugi (杉の大スギ), also known as "Osugi-san" by locals, is the world's tallest Japanese Cedar (Cryptomeria japonica) and is said to be over 3000 years old. [1] It is located within the grounds of Yasaka Jinja in Ōtoyo , Kōchi Prefecture on Shikoku island in Japan .
Japan has significant diversity in flora. Of approximately 5,600 total vascular plant species, almost 40% are endemic. [1] This richness is due to the significant variation in latitude and altitude across the country, a diversity of climatic conditions due to monsoons, and multiple geohistorical incidences of connections with the mainland.

Chamaecyparis obtusa (Japanese cypress, hinoki cypress [2] or hinoki; Japanese: 檜 or 桧, hinoki) is a species of cypress native to central Japan in East Asia, [3] [4] and widely cultivated in the temperate northern hemisphere for its high-quality timber and ornamental qualities, with many cultivars commercially available.
