In p>1917, Mitsubishi Motors registered a logo with a three-petal diamond pattern, which also contains a family history. In 187, Mitaro Iwasaki, who was born in a noble family, founded the ninety-nine trading company, which was renamed Mitsubishi Chamber of Commerce in 1873. In the Mitsubishi Chamber of Commerce, there are three close friends of Mitaro Iwasaki, all of whose names have the word "Chuan", and the Chamber of Commerce uses "Mitsubishi" word mark. Mitsubishi's graphic symbol is a combination of the family symbol "Sanduanling" of Iwasaki family and the family symbol "Sanbailing" of Tosa's Yamauchi family. The three diamond symbols were originally used as the flag of the Ninety-nine Chamber of Commerce. It was a famous ocean-going shipping company in Japan in the 197s. Many Mitsubishi companies developed from this company in the future, and Mitsubishi Motors was no exception. The three diamonds in the trademark represent three diamonds, which contain three principles of Mitsubishi Corporation: common responsibility to society, honesty and fairness, and enhancing international understanding through trade. This figure is concise, bright and compatible with the company name, so that people can recognize this sign no matter where it appears in the world today.
