I have that exact same Toto toilet tank in the states.
Buttons are more common on dual flush toilets. One button is for a small flush, the other button (or both pressed at once) is a larger flush. These toilets are pretty common in parts of the world where water is in short supply and or expensive.
Lever based dual flush systems also exist, but they’re usually less common. You push for one type of flush and pull for the other.
That said, my folks have old push button toilets from the late 70’s. They’re single flush, and the button is side mounted. The buttons were just cool for the sake of cool, and lots of American plumping supply places still sell new parts for these toilets.
TL;DR: they exist in the US, but you’ll see a lot more out in the dry ass west.

You can buy these in the US. They sell them in Home Depot.

Whoa, two different flush settings? Such a simple change yet I’d never thought of that. Thanks, that was super cool.

I got one that has a normal handle, but you lift for a half flush and push down for a full one.
