Mitsubishi is not a single company. It is a group of many independent companies, most of which use the name "Mitsubishi", but will not simply call themselves "Mitsubishi". There are 28 core members of Mitsubishi kinyokai (also known as Friday Club), about 500 member companies of Mitsubishi, about 400 companies with "Mitsubishi" in their names, and hundreds of companies without "Mitsubishi" in their names.
