The camphor tree has the poetic Latin name, Cinnamomum camphora. Their canopies extend broadly, so they are vulnerable to wind damage and rot. Their wood is prized for its fragrance and also its tendency to ward off insects, so if you ever find chunks, take them home and stash them where household insects gather.
Our friends, the Marubayashis, sent us this photo of a particularly large specimin which is located in Ueki and is called the Jakushinsan no kusu (you can Google it). My daughter’s elementary school also had a large camphor planted in Meiji 30, but it succumbed to age a few years agó. However, the arborists pointed out the robust root system, so it was fenced off and is shooting back up again. (Photo below). Thank you, Marubyashi-san. - William
