Atsu is a cross-cultural given name with distinct roots in Japanese and in Ewe-speaking communities of Ghana and Togo. In Japanese, it can be written with kanji such as 篤, 厚, 敦, or 惇, conveying senses like “earnest,” “kind-hearted,” “thick/warm,” and “sincere.” It appears both as a standalone masculine name and as a familiar short form for names beginning with Atsu-, including Atsushi, Atsuo, Atsuko, Atsumi, and Atsuya; exact nuance depends on the chosen characters.

In Ewe usage, Atsu is traditionally bestowed on a male twin and broadly carries the meaning “twin” or “one of a pair of twins,” a role that holds special cultural regard; the name also occurs as a surname. A francophone West African spelling, Atsou, is sometimes seen. In Japan, the element gained visibility through figures such as Princess Atsu (Atsuhime, 篤姫), and it remains current in modern given names and nicknames (Atsu-kun, Atsu-chan).
