Sei is Japanese in Origin.

Sei is a Japanese given name written せい in hiragana and romanized in Hepburn as Sei from a two-mora sequence /se.i/, often realized [seː]. Its root language is Japanese, though most name spellings use Sino-Japanese on’yomi readings of kanji borrowed historically from Chinese. The earliest recoverable written form is therefore the kana reading せい paired with chosen characters. Literal sense changes by spelling: 聖 holy, 星 star, 誠 sincerity, 清 clear, 生 life, or 成 accomplishment.

As a personal name, Sei appears for men and women, with modern databases often showing stronger male use. It is also a surname. The religious register of 聖 links it to Buddhist and Christian vocabulary for sanctity, while 誠 has an ethical, literary flavor. Notable bearers include Yoshimoto Sei, co-founder of Yoshimoto Kōgyō, and the Heian writer Sei Shōnagon, whose Sei is a court-name element.
