Kato

The origin of the surname Kato

Kato (加藤) joins characters for “add” and “wisteria.”

What kind of surname is Kato?

As a toponymic (locational) surname, the surname Kato originally described where its bearer lived or came from — a village, region, landscape feature or landmark. When people moved from one place to another, neighbours often identified the newcomer by their place of origin, and that association became a lasting family name. Some toponymic surnames name a specific town or county; others describe the local terrain, such as a hill, wood, field, ford or bridge beside which a family lived. These names are a kind of map of migration and settlement, recording where earlier generations put down roots.

How Japanese surnames work

Japanese surnames are written in kanji and are overwhelmingly toponymic — they describe natural features and places, which is why so many contain elements for field, mountain, river, tree, village and rice paddy (as in Tanaka, “middle of the rice field”, and Yamamoto, “base of the mountain”). Most families adopted surnames only after 1875, when the Meiji government required them, drawing on the landscape around them. Because meaning lives in the characters, the sense of a Japanese surname is tied to the specific kanji used.
