Is there a Japanese last name that means clever?

There isn't a Japanese last name that directly translates to "clever." Japanese surnames are typically derived from:

* Place names: Like "Yamamoto" (mountain base) or "Tanaka" (rice field).

* Occupations: Like "Hayashi" (woodsman) or "Suzuki" (bell maker).

* Characteristics or objects: Like "Kishi" (shore) or "Mori" (forest).

While there aren't direct translations, you could look for names that evoke a sense of cleverness, wisdom, or intelligence:

* 聡 (Satō): Means "wise" or "intelligent."

* 賢 (Ken): Means "wise" or "clever."

* 知 (Chi): Means "knowledge" or "wisdom."

* 明 (Aki): Means "bright" or "clear," which can imply intelligence.

These kanji characters could be incorporated into existing surnames, or even used to create new ones.

Remember that choosing a name is a personal decision, so consider what feels right for you and your family.
