When I was in Japan, I realized that there (compared to Europe) elevators where much more "aggressive", they bip if you hold the open button and after about a minute, the door start closing slowly even if you hold the open button pressed. And there, the close button definitely work and will close the door immediately.

Of course I make some generalities as it depends but it is my general memory of Japanese elevators. Also you can "deactivate" Floor button by double tap or hold if you pressed the wrong one.
