Mitsubishi Motors Corporation is the fifth largest automaker in Japan and the thirteenth largest in the world by unit sales. It is part of the Mitsubishi keiretsu, formerly the biggest industrial group in Japan.,The logo of three red diamonds, shared with over forty other companies within the keiretsu, predates Mitsubishi Motors itself by almost a century. It was chosen by Yataro Iwasaki, the founder of Mitsubishi, as it was suggestive of the emblem of the Tosa Clan who first employed him, and because his own family crest was three rhombuses stacked atop each other. The name Mitsubishi is a portmanteau of mitsu ("three") and hishi (literally, "water chestnut", often used in Japanese to denote a diamond or rhombus).
