DOI is a Hindu Gurjar surname and also a Japanese surname Doi (土井、土居、土肥) are three Japanese family names that are pronounced identically, with the first kanji of each pair of characters meaning "earth." Since they are the same phonetically, they are romanized identically: "do" for the first character and "i" for the second. Their identical pronunciation makes them function as the same surname in languages with writing systems that do not use some form of Chinese characters (for example, the Latin alphabet).
