Yearly Tree Trunk Growth at ARK Hills and Roppongi Hills

For the opening in 1986, many cherry trees were planted with the aim of restoring the sight of the old cherry trees that once blossomed in the area. At that time, the trunk thickness of the newly planted trees averaged 28cm. After more than 30 years of careful care (2019), this had increased to 145cm in average and still keep growing moderately.
