Yamaha often gets overlooked for instruments, I think a lot of this is that we don't expect a company that makes jetskis and motorcycles to also know what they're doing with guitars, saxophones, and pianos, but they actually make good quality stuff.

It's more accurate to think of Yamaha as a conglomerate that owns several different companies. It's just that a lot of those smaller companies are also named Yamaha

Fun fact, the Yamaha logo is an image of three tuning forks, laid atop each other.
