Mitsubishi Motors

The Mitsubishi three-diamond mark (known as the 'three diamonds' or 'Mitsubishi mark') dates back to the 1870s and combines the Iwasaki family crest (three stacked rhombuses) with elements associated with the Tosa Clan; the name 'Mitsubishi' itself comes from 'mitsu' (three) and 'hishi' (water chestnut, rendered as a diamond shape). The three-diamond emblem has been used continuously across the group's businesses and became the core automotive identity when Mitsubishi began producing cars in the early 20th century. Over time the emblem has been presented in various refinements and contexts (badging, grille design, corporate identity) while preserving the simple geometric three-diamond form. The mark is closely associated with Mitsubishi’s red brand color and has been used to signal engineering heritage and the company’s ties to the historic Mitsubishi zaibatsu.
