The Mitsubishi trademark is a three-petal rhombus diamond pattern registered in 1917. Mitsubishi embodies the company's three principles: assuming collective responsibility to society, honesty and fairness, and promoting international understanding and cooperation through trade. In 1870, Iwasaki Yatarō, who came from a distinguished family, founded Kujiu Trading Co., Ltd., which was renamed the Mitsubishi Chamber of Commerce in 1873. There were three close friends of Iwasaki Yatarō in the Mitsubishi Chamber of Commerce, and their names all had the character "Kawa", so the Mitsubishi Chamber of Commerce used the word "Kawa". The word trademark "Mitsubishi"; the three-petal rhombus diamond pattern of the graphic trademark evolved from the logo on the Iwasaki family's shipping ships and the sampa leaf logo of the feudal lord's house. Since then, all members of the Mitsubishi Group have used this trademark. In 1970, Mitsubishi Motors Corporation became independent from the Mitsubishi Group. The company's cars and off-road Jeeps (Mitsubishi Jeep) are of high quality and superior performance, making the Mitsubishi trademark famous all over the world.
