History & Origin

Mitsuko is a traditional Japanese girl's name joining mitsu - most often 'light' or 'shine' - with ko, 'child,' the ending that closed a great many Japanese women's names for generations. Read together it is usually 'child of light.'

In the United States Mitsuko appears from the nineteen-tens through the early nineteen-eighties, carried by the Issei immigrant generation and their American-born Nisei daughters. Always rare here at only a few dozen births in its best year, it is a name that quietly records a community's history.
