An electronics company which is located in Tokyo, Japan. They make a wide array of computer equipment, including keyboards, mice, CD-ROMs, CD-R drives, floppy drives, and much more. Generally, they are widely recognized as a company where you get the most bang for your buck, but aren't relied on to make industrial-strength stuff (i.e. Western Digital). Although, I have to admit, my Mitsumi CR-2801TE has made me think about Mitsumi much differently. I'd much rather get a component manufactured by Mitsumi as opposed to HP.
