From Dragon Ball wiki:
After much contemplation, Akira Toriyama (the creator of Dragon Ball) could not decide on a name for his "Kame" attack, so he asked his wife. She told Akira that it would be easy to remember the name of the attack if he uses the name of...
...the first king and unifier of the Hawaiian Islands. Every June 11 Hawaiians celebrate Kamehameha Day in his honor. He also appears on the Hawaiian state quarter.
