I never figured out why CMU would have enough name recognition in Japan to show up in an anime.
Don’t miss the scene where Japan is saved by a game of Hana Fuda
CMU is a solid computer science and engineering school which has found a way to get its name thrown in up there with the likes of MIT and Caltech (can't tell you how many times I've seen CS-oriented folks praise CMU like it's MIT). It's also possible that someone at the studio has a connection to CMU and wanted to include it.
Has any other director managed to get away with making the same film three times?

Now, is that Digimon (2000), Summer Wars (2008) or Belle (2021)?
I haven't seen Belle, so can't comment on that one.
