Meaning & origin

Tomoko first appeared in U.S. records in 1923, reflecting Japanese immigration patterns of the era. Its peak year was 1925, though it never reached a high rank. The name has a stable trajectory, with very low usage in recent decades; in 2025, it remains outside the top 1000. Tomoko exemplifies the traditional Japanese feminine suffix 'ko', which was especially fashionable for girls born in the early 1900s. While it never saw widespread popularity in the United States, it maintains cultural significance as a classic Japanese name.

Tomoko is a Japanese feminine name composed of two elements: 'tomo' (智, meaning 'wisdom, intellect') and 'ko' (子, meaning 'child'). It has been used in Japan for centuries, though its popularity peaked in the early 20th century. The name reflects traditional Japanese naming conventions where 'ko' was commonly appended to female names, especially during the early 1900s.
