Three diamond embelem of Mitsubishi

Logo Mitsubishi

Mitsubishi, (literally means three diamonds in english), is a japanese company established in 1870 as a shippnig firm by Koyata Iwasaki.This three-diamond embelem is signifying the meaning of the word Mitsubishi,which is combination of the words "mitsu" and "hishi." "Mitsu" means three. "Hishi" means water chestnut, and the word is used to denote a rhombus or diamond shape. As customary, "hishi" is pronounced "bishi" when it forms a latter part of a word, hence the combination of "mitsu" and "hishi" reads "mitsubishi."
Yataro Iwasaki, the founder of the old Mitsubishi organization, decided on the three-diamond mark as the emblem for his company.The mark is said to be an arrangement of two family crests; the three-oak-leaf crest of the Yamauchi family, Lords of Tosa, where Yataro was born, and the three-tiered water chestnut crest of the Iwasaki family.

Origins of the Famous Emblem of Mitsubishi

Adidas

Logo 1972 to 1996

Logo after 1996

In 1996 this logo replaced the 1972 Adidas logo. The logo became the Adidas’ worldwide corporate logo. It represents performance and the future of the Adidas brand identity. Again like all former Adidas logos, it features three main elements. The three leaves in the 1972 logo got replaced by a triangle cut into three pieces. Apart from the triangle visualizing the future focused movement, it can also been seen as a strong visual representation of the classic Adidas sneaker with its three stripes on the side. The Adidas name is a pormanteau of its founder’s name Adolf (Adi) Dassler. The three elements in this and all other Adidas logos are said to represent Dassler’s three sons.

Subaru: The Star cluster

The automobile manufacturing division of Japanese transportation conglomerate Fuji Heavy Industries (FHI),Subaru is  the twenty-sixth biggest automaker by production worldwide in 2011.Subaru ,the name of a star cluster in the Taurus constellation is known as Pleiades in Greek mythlogy. This name was given to this company by the first president of Fuji Heavy Industries Ltd. (FHI), Kenji Kita.Clearly, this is one of the clusters much loved by the Japanese from ancient times.

Moreover the Subaru word in Japanese means to unite together. Thus the current logo is having all these six stars which actually present the six merger companies of Subaru.
