Issei is Japanese in Origin.

Issei is a Japanese masculine given name (いっせい) whose meaning depends on the kanji. Common kanji writings include 一誠 (“steadfast sincerity”), 一星 (“first/one star”), 一成 (“accomplishment”), and 一生 (“whole life; lifelong”). Because the first element 一 means “one; first,” the name often carries senses of unity, new beginnings, or wholehearted purpose. It is typically romanized Issei, with alternative forms Issey (popular in English) and, less often, Isei or Issay.

In Japan the name has been used since the late 19th–20th centuries and remains familiar today; designer Issey Miyake (三宅一生) helped make the Issey/Issei spelling recognizable abroad. Note that the identical-sounding term 一世 (Issei) in Japanese American and Brazilian history labels first‑generation immigrants, a sociological usage distinct from the given name. While primarily masculine, it can be unisex in modern contexts. Diminutives are uncommon in Japanese, though English speakers sometimes shorten it to Issy.
