Meaning & origin

Seira is a name with dual heritage, rooted in Japanese and occasionally used as a variant of Sara in English. In the United States, Social Security data shows Seira first recorded in 1989, with a peak in usage in 1998. The name has maintained a stable trajectory since then, though it remains outside the top 1000. Its appeal likely stems from its simple, melodic sound and positive meanings in Japanese, such as 'clear' or 'star.' Parents drawn to cross-cultural names may find Seira an attractive choice that is both easy to pronounce and distinctive.

Seira is primarily a Japanese name, written with various kanji combinations such as 星良 (sei 'star' + ra 'good') or 清良 (sei 'pure' + ra 'good'). As a Japanese name, it gained modest popularity in the late 20th century. In English-speaking contexts, Seira is occasionally used as a variant of Sara or Sarah, though this is less common.
