Kido-san is Japanese in Origin.

Kido-san combines the Japanese surname Kido with the honorific -san, a polite title akin to Mr./Ms.; the suffix is not included on legal given names. In Japanese, addressing someone as Kido-san simply means “Mr./Ms. Kido,” so as a baby name it’s unconventional; dropping the honorific to use Kido alone is the culturally accurate form.

Kido (most commonly 木戸 “wooden gate,” also 城戸 “castle gate”) is an old samurai-era family name borne by figures such as Meiji statesman Kido Takayoshi. As a given name it is rare in Japan but could be adopted as a gender-neutral modern choice abroad. Meanings vary with kanji, but all point to “gate/door,” evoking thresholds and protection. Variants and romanizations include Kidō (with macron), Kidou, and Kido (standard ASCII). Related honorifics like -chan or -kun are for address only and are not part of registered names.
