How does New Japan handle the Heavyweight titles side plates long term?

like the names and stuff. I havent been watching too long so may be a newbie question lol, but i just realized that if the side plates have the names of every former champion, then eventually they have to run out of space and probably already have at one point or another.

so how do they handle that? like do they redesign the side plates to have smaller name plates and fit more? remove the oldest one when a new one happens and have it be like a "these are the last X number of champions"?
