Toshiko

Toshiko is a feminine Japanese name composed of elements that typically mean 'alert' or 'valued' (toshi) and 'child' (ko), though exact meanings can vary depending on the kanji characters used to write it. The suffix '-ko' was particularly common in female Japanese names during the early and mid-20th century. Toshiko represents traditional Japanese naming conventions while being relatively recognizable to Western ears.

Outside Japan and Japanese diaspora communities, the name remains uncommon but has been embraced by some parents seeking a name with authentic Japanese cultural roots and a pleasant, accessible sound.
