I had this idea that Fujitsu was one of those Japanese conglomerates that had operations in all kinds of markets, from electronics to heavy earth moving equipment to air conditioners to locomotives. But that doesn't appear to be the case so I'm wondering which company I'm confusing them with.
Edit I think I was thinking of Mitsubishi.
Probably Panasonic. They're like the Apple of the B2B world. Except they also make everything
Fujitsu was a telco equipment spinoff from Fuji Electric, so Fujitsu do/did make a lot of things that would be in a phone exchange building over its history, from air conditioners to terminals to actual mainframes. Just not as everything as Mitsubishi, which was a do-all procurement company for the new government when the Tokugawa stepped down.
