The three-diamond trademark of Mitsubishi is well-acquainted with Filipinos and connotes quality and reliability. Companies that share the same logo are evident here in the Philippines. Such as Mitsubishi Electric, one of the world’s prime names in the manufacture and sales of electrical and electronic products and systems used in a broad range of fields and applications. Therefore, it is plausible that the Mitsubishi logo in the country is recognized.

For over 150 years, the Mitsubishi mark has embodied the tradition and earned the trust and confidence of the people. Synonymous with quality and reliability, the value of the mark with its products and services in every Mitsubishi group company is a top priority, especially on Mitsubishi Electric.

Mitsubishi derived from Mitsuhishi denotes three diamonds. This mark was chosen by Yataro Iwasaki, the founder of the first Mitsubishi organization as the insignia of the company. It signifies the three-leaf oak family crest of the Yamanouchi family from the Tosa Clan, Yataro's first employer, and the three stacked rhombuses of his family crest combined.

Though Mitsubishi Electric shares the same mark with fellow Mitsubishi group companies, they all maintain the rigorous ethical standard that embodies their origin through providing superior products and services. These play a huge value on the three-diamond mark as a symbol of quality and reliability. They are meticulous in utilizing the insignia to maintain and protect its image and distinction thus averting improper use.

Taking cognizance of this, Mitsubishi has carried out legal actions such as registration and establishing a trademark committee and liaison group to work and ensure that the mark is being utilized properly and that reinforces the Mitsubishi identity. While Mitsubishi Electric constitutes manuals, handbooks, and guidelines to provide instructions and references to its affiliates.
