I heard many people wear shoes in the house in the USA. In Japan, we don't wear shoes inside of the house. We take off the shoes at the entrance and wear slippers. I have some questions about it. My question no1 is do people wear the same shoes in the house? No2, if so what will you do if it is rain? No 3, if not, do you have shoes only for at home? Isn't it different from slippers? No4, what do you do if you have guests? Do they wear the same shoes? Or do you ask them to change the shoes?? I'm very curious.
