How old is a Wagyu cow before slaughter?

I'm curious, how long does a Wagyu cow typically live before it's slaughtered? I've heard that these cows are highly prized for their marbled meat, but I'm not sure about the specifics of their lifespan. Do they live longer than other breeds of cattle, or is it similar? It would be interesting to know if there's a standard age at which Wagyu cows are typically raised for slaughter, and what factors might contribute to that decision.
