The question is: do you often see people taking their shoes off when they go to a house on Japanese TV shows and movies?

Yes, you do. It would be weird enough not to that it would jar the suspension of disbelief.

In Greek shows, everyone wears their shoes in the house, even though nobody in Greece actually does. We've accepted it as "one of the things they do on TV", but every Greek home has a bunch of slippers you can wear near the door.
