What Does the Name Seiji Mean?
Seiji is a Japanese masculine given name written with two kanji, and its meaning depends on which characters are chosen, since the reading alone does not fix a single sense. The most common first element is 清 (sei), "pure, clear," paired with 治 (ji), "govern, rule, heal," giving the sense "pure governance" or "clear rule." Other frequent spellings use 誠 (sei), "sincerity," 正 (sei), "correct, upright," or 聖 (sei), "sacred," combined with 治 or with 司 (ji), "official, administer." The name can also be written 征爾, where 征 (sei) means "subdue" and 爾 (ji) is a classical particle with no independent meaning here. In all of these, sei is a Sino-Japanese reading rather than a native Japanese word, so the literal sense comes from the individual characters, not from the sound.
Seiji Name History & Origins
Seiji follows the standard Japanese pattern of male names made from two kanji read with Sino-Japanese pronunciations. Combinations such as 清, 誠, or 正 as the first element and 治 or 司 as the second grew out of naming conventions that developed over many centuries, with the second character frequently suggesting governing, ordering, or service. The character 治 has several readings in names, including osamu, haru, nao, and ji; it also appears in era names, as in Meiji (明治), where it is read ji. Spoken in Japanese, Seiji is three morae. A widely known bearer is the conductor Seiji Ozawa, whose given name is written 征爾.
