].
The tree is harvested from the wild for its wood which is used locally and commercially. It is often grown as an ornamental, especially in its native country.
This species has been exploited for its timber in the past 100 years, but the population reduction is not likely to exceed 30% over three generations (100 years), it is more likely to be in the range of 20-29%, hence this species is listed as Near Threatened. The reduction is based on direct exploitation, and there is also a growing impact from browsing by deer in central Japan as many seedlings are eaten, so the tree almost qualifies as Vulnerable..The plant is classified as 'Near Threatened' in the IUCN Red List of Threatened Species(2013)[
