Romaji is the Romanization of the Japanese language, which means writing Japanese words using the Latin alphabet. It helps non-Japanese speakers read and pronounce Japanese words without needing to learn the complex scripts of Hiragana, Katakana, and Kanji. Romaji is often used in language learning, signage, and for typing Japanese on computers and smartphones. There are several systems of Romaji, with the most common being Hepburn, Kunrei-shiki, and Nihon-shiki. Each system has its own rules for representing Japanese sounds, but they all aim to make the language more accessible to those unfamiliar with traditional Japanese writing.
