A lot of companies in Japan have a heavy industries branch or similar. Yamaha has all kinds of verticals as they’re happy to sell you a piano or a motorcycle (or both!)
It’s not so much diversification, but the fact that many of them were zaibatsu, the only ones able to do anything other than farming. They just had a huuuuge head start.
Subaru used to be a part of Fuji Heavy Industries, who actually started out making aircraft. They’ve since been renamed to simply “Subaru Corporation”, apparently.

wind turbines, too.
