Mitsubishi The Mitsubishi Group (also known as the Mitsubishi Group of Companies or Mitsubishi Companies) is a group of autonomous Japanese multinational companies covering a range of businesses which share the Mitsubishi brand, trademark, and legacy.
The Mitsubishi company was first established as a shipping firm by Yataro Iwasaki (1834–1885) in 1870. In 1873, its name was changed to Mitsubishi Shokai. The name Mitsubishi consists of two parts: "mitsu" meaning "three" and "hishi" (which becomes "bishi" under rendaku) meaning "water caltrop" (also called "water chestnut"), and hence "rhombus", which is reflected in the company's logo. It is also translated as "three diamonds".
