I'll issue a warning so you won't someday make the same mistake I did when I was younger.  Don't confuse bonsai, the pruning of miniature trees and shrubs, with banzai, which was a cry that was used by Japanese soldiers during World War II.  The complete phrase was Tenno Heika Banzai, which means 'Japanese Emperor may he live for ten thousand years'.  It was used by Mr. Miyagi in the Karate Kid movies, and it can be used as a greeting when meeting the Japanese Emperor to wish him long life.  

Hiking the timberline trails on Mt Hood, I often found the nature-made inspiration for Bonsai trees.  It was amazing to realize a two-foot-tall tree could be so beautiful and so ancient.  

Where I run I see numerous little ceder trees as gnarled as bonsai. I'm tempted to "re-home" one.
