Kaido is Estonian, Japanese in Origin.

Kaido is a masculine given name with distinct roots in Estonian and Japanese. In Estonia, it likely developed as a masculine counterpart or diminutive extension of the feminine Kaidi (a local form of Katariina/Catherine), ultimately from Greek Aikaterine, often interpreted as “pure.” In Japanese, Kaidō (海道) is primarily a surname and common word meaning “sea route” or “coastal road”; as a given name it is rare, though the Kaidō/Kaidou spelling appears in fiction and modern pop culture.

Estonian usage rose in the later 20th century and remains familiar; bearers include épée fencer Kaido Kaaberma and chess grandmaster Kaido Külaots. The name also occurs in Finland through Estonian influence. Short forms include Kai; a related feminine form is Kaidi. Japanese romanizations vary: Kaidō (with macron), Kaido, or Kaidou. The name is sometimes associated with the similar Japanese Kaito (海斗/魁人, etc.), but that is etymologically separate.
