History & Origin

Seina is used in Japan as a girls' name, and like all Japanese names its sense depends on the kanji: sei can mean 'star', 'clear' or 'holy', na can be 'greens' or simply a sound. No single meaning can be claimed for the romanized form. English speakers may also hear the Italian city Siena in it. The routes are uncertain, which we note (said 'SAY-nuh').

In the U.S. it appears only rarely for girls. Rare, soft, and character-dependent.

Did you know? Japanese names carry their meaning in the characters, not the sound — so Seina may hold 'star', 'clear' or 'holy' depending on the kanji a family picks. In English it also echoes Siena, the Italian city. Routes uncertain, which we note.
