Kunrei-shiki romanization

Kunrei-shiki romanization (Japanese: 訓令式ローマ字, Hepburn: Kunrei-shiki rōmaji), also known as the Monbusho system (named after the endonym for the Ministry of Education, Culture, Sports, Science and Technology) or MEXT system, is the Cabinet-ordered romanization system for transcribing the Japanese language into the Latin alphabet. Its name is rendered Kunreisiki rômazi in the system itself. It is taught in the Monbushō-approved elementary school curriculum. The ISO has standardized Kunrei-shiki, under ISO 3602.

Kunrei-shiki is based on the older Nihon-shiki romanization, which was modified for modern standard Japanese. For example, the word かなづかい, romanized kanadukai in Nihon-shiki, is pronounced kanazukai in standard modern Japanese and is romanized as such in Kunrei-shiki. The system competes with the older Hepburn romanization system, which was promoted by the SCAP during the Allied occupation of Japan, after World War II.
