Don’t Forget The Slippers

Japanese establishments like hotels and restaurants normally provide slippers that are meant to be worn when using the toilet. You will notice that even homes have indoor or house slippers as well as toilet slippers. If you can, bring with you a pair of slippers when visiting someone’s home as shoes are expected to be taken off and slippers to be worn. Don’t use the indoor slippers when going to the toilet as the toilet slippers are there for this very reason. The toilet is viewed as dirty so forgetting to change the toilet slippers for the indoor ones after using them is considered impolite.
