Terminology in Bonsai
Some of the Japanese vocabulary we use in bonsai is wide spread. Other terms are not as well known, and while
they are not necessary to enjoy the art of bonsai itself, it can also be nice to be familiar with the Japanese phrases and
vocabulary.
Many Japanese words have multiple meanings, some related to Bonsai, some not. For instance, the word bankan most
commonly means "a trunk with many curves, like a coiled snake", but also means a gnarled trunk, or a flat slab of
rootage instead of individual roots (much as one typically finds on olive trees, for instance). Other words have a
common usage translation, and a different literal translation. The word mame literally means "pea," or "bean" in
Japanese, though we use it to denote bonsai of the smallest size category.
I could never include all of the Japanese words associated with bonsai, nor all of their many meanings, without this
turning into a whole Japanese language lesson. However, as I learn them I will share them here. While I may not
include all of the non-bonsai definitions of the words, I will include as many meanings as I can, as well as literal
translations where applicable.
