Life Bank paper was originally made in the 1960s by Mitsubishi Paper Mills, for Mitsubishi Bank (now known as Bank of Tokyo-Mitsubishi UFJ). The paper needed to be strong, smooth, and usable for a variety of tasks. For example, it needed to handle writing, typing, and being passed between many people.
In the 1960s, Mitsubishi Bank needed some good paper. They needed paper that was easy to write on and could be typed on too. It needed to withstand repeated handling and stand the test of time.
The result was known as Mitsubishi Bank Paper – made by Mitsubishi Paper Mills. It was discontinued ages ago, but has been given new life in recent years, by companies such as Life Co.
It’s interesting to note that this is the same Mitsubishi that’s more widely known for making cars. This is why every sheet of bank paper has a characteristic watermark, “THREE DIAMONDS”, in reference to the logo of the Mitsubishi group.
