In 1917, Mitsubishi Motors registered a three-petal diamond-shaped logo. This pattern also contains a piece of family history. In 1870, Yatarō Iwasaki, who came from a distinguished family, founded Kujiu Trading Company, which was renamed Mitsubishi Chamber of Commerce in 1873. In the Mitsubishi Chamber of Commerce, there are three close friends of Yataro Iwasaki, whose names all have the character "Kawa", and the Chamber of Commerce uses the "Mitsubishi" word trademark.

Mitsubishi's graphic logo is a combination of the family symbol "Sandan Hishishi" of the Iwasaki family and the family symbol "Sanbarishi" of the Yamauchi family, lord of the Tosa domain. The three diamond-shaped logo was originally used as the flag of the Kujiu Chamber of Commerce, a famous Japanese ocean-going shipping company in the 1870s.
