Meaning & origin

Tomiko is a Japanese feminine name that combines 'tomi' (wealth, fortune) with the common suffix 'ko' (child). Although it has never been a widely used name in the United States, it achieved its highest recorded popularity in 1975, the peak year for the name. The name's trajectory has been stable since then, with very few annual births, and it does not have a current 1-in-N statistic due to its rarity, as it did not rank in the most recent year with available data. Tomiko was first recorded in 1912, but it has never been among the top names in any state. The name is most naturally paired with other Japanese names like Yoshiko for sisters or Kenji for brothers, reflecting its cultural origin.

Tomiko is a Japanese feminine name formed from the element 'tomi' (wealth, fortune) and the suffix 'ko' (child). Names ending in -ko were historically common for girls in Japan, particularly during the mid-20th century. The name was occasionally used among Japanese Americans and saw peak usage in the 1970s, though it remains relatively rare overall.
