MitsubishiThe Mitsubishi logo is an integration of two family logos, and originally represented three water chestnuts. It’s derived from the three-layer chestnut family crest of Yataro Iwasaki, founder of Tsukumo Shokai, and the three-leaved oak family crest of the Yamanouchi family, from the Tosa Clan. As for the name, it literally means ‘three water chestnuts’ – Mitsu means three, and Hishi is the word for water chestnut (when there’s an ‘h’ in the middle of a Japanese word, it’s often pronounced as a ‘b’).
