Honda was born in Kōmyō village, Iwata District, Shizuoka, near Hamamatsu on November 17, 1906. He spent his early childhood helping his father, Gihei Honda, a blacksmith, with his bicycle repair business. At the time his mother, Mika Honda, was a weaver. Honda was not interested in traditional education. His school handed grade reports to the children, but required that they be returned stamped with the family seal, to make sure that a parent had seen it. Honda created a stamp to forge his family seal out of a used rubber bicycle pedal cover. The fraud was soon discovered when he started to make forged stamps for other children. Honda was unaware that the stamp was supposed to be mirror-imaged. His family name 本田 is symmetrical when written vertically, so it did not cause a problem, but some of other children's family names were not.
