I had a rumor that there is an awesome machining company with the world top level technique and equipment. Senbokuya Co. is located in Yokohama City, 20 miles south west of Tokyo. I found a ultra-small helicopter which I could pick up my fingers. I carefully looked it up with a magnifier, and found windows and a hole in its fin. How could they "cut" such a small helicopter, which could knock down with a feather? "That's awesome, isn't it?" said Eiji Senbokuya, founder and CEO of Senbokuya Co. "Even if you have a machine, you can hardly make it. You need skilled craftsmen, the latest cutting machines, and great experience. If one of these factors fails, you can never accomplish such a difficult work."
