Nihon-shiki romanization
A romanization system for Japanese that strictly follows kana spelling, unlike Hepburn which reflects pronunciation. Used mainly in linguistic contexts and by some native speakers.
In Nihon-shiki romanization, 'chi' is written as 'ti'.
Hepburn romanization is based on English pronunciation and is more common in signs and passports. Nihon-shiki is more systematic for Japanese phonology.
Kunrei-shiki is a modified version of Nihon-shiki, standardized by the Japanese government. They are very similar but differ in a few kana representations.
Formed from 日本式, “Japanese style,” and ローマ字, “Roman letters.” The romanization system was devised by 田中館愛橘 and presented in 1885.
