Many hotels in Japan provide slippers in each room. Slippers are provided for each guest, and almost all of them are for one use only, so they are hygienic. After a long day of sightseeing, take off your shoes, change into slippers, and relax in your room. If you don't use the slippers, why not take them home and use them on your flight home?
In Japan, where it is customary to take off one's shoes at the entrance of the house before entering the room, many households keep slippers for guests on hand, and this has become a part of Japanese hospitality. However, if you are staying at a Japanese-style inn, it is against etiquette to wear slippers in the tatami room. Be careful not to do this.
