nope! Hitachi sold their Magic Wand brand a while ago, specifically to distance themselves from the association (look how well that worked lol). Good thing too because the new owners have been actually iterating on the product ever since and those vibrators are now even more incredible than their fame let on.
For everything else though, yeah Hitachi is still a conglomerate.
I was also curious about this. The only car they produced, as far as I could find, was a concept car featured in the 2015 Tokyo Motor Show. They called it the "Sports Ride Concept."
Similarly Peugeot makes pepper grinders, bicycles, cars and whatnot. Probably sewing machines at some point, idk. There are quite some bike manufacturers that used to make sewing machines and typewriters in the past.
