Japanese name meaning 'half three' or associated with the legendary ninja Hattori Hanzō; connotes warrior skill.
Hanzo is a Japanese masculine name whose components and character vary by bearer, but most commonly combines the kanji 半 (han, meaning 'half') with 蔵 (zō, meaning 'storehouse' or 'treasury') — a compound that has classical precedent in Edo-period Japan. The name belongs to a tradition of Japanese naming in which phonetic balance and auspicious meaning in the written characters could be chosen somewhat independently, giving families room to imbue names with aspiration as well as sound. The name's most famous historical bearer is Hattori Hanzō (c.
1542–1596), the Iga Province ninja and samurai who served Tokugawa Ieyasu during Japan's tumultuous Sengoku period of civil wars. Hattori Hanzō became legendary for his intelligence-gathering operations and is credited in some accounts with saving Ieyasu's life during a critical escape through hostile territory. His legacy passed into Japanese folk tradition and then into global pop culture, most prominently through Quentin Tarantino's Kill Bill (2003), where the character Hattori Hanzō — now an Okinawan swordsmith — became one of cinema's iconic supporting roles, played by Sonny Chiba.
The name also features in the video game Overwatch, where Hanzo Shimada is a skilled archer, extending its reach into gaming culture. For Western parents, Hanzo carries the appeal of Japanese phonetic elegance — two clean syllables, equal stress, a satisfying rhythm — combined with the romantic weight of the ninja archetype. It is a name that travels well across languages without distortion, making it one of the more genuinely cross-cultural Japanese names available to non-Japanese families, though it remains rare enough outside Japan to feel genuinely distinctive.
