Details

The keyword for 尉 is military officer. This kanji refers to a rank in the military, specifically a commissioned officer of junior grade, equivalent to ranks such as lieutenant or captain depending on the context. In ancient China, it originally denoted an official responsible for military or law enforcement duties, and the character carried connotations of authority and the power to pacify or suppress. In modern Japanese, it remains primarily used in military and historical contexts to designate officer ranks.
