Mitsubishi's three-diamond mark comes from the wider Mitsubishi group's name and heritage, with "mitsu" meaning three and "hishi" meaning water chestnut, a word commonly used for a diamond or rhombus shape in Japanese.
The emblem is historically linked to the three-leaf crest of the Tosa clan and the three stacked rhombuses of the Iwasaki family, the family of Mitsubishi founder Yataro Iwasaki. Mitsubishi Motors inherited the mark from the Mitsubishi industrial group when its automotive business developed from Mitsubishi Shipbuilding and Mitsubishi Heavy Industries. The modern automotive identity keeps the red three-diamond symbol as a compact, symmetrical sign of continuity, engineering, and Japanese industrial heritage.
