Very few Japanese homes have installed carpeting. Older houses and apartments often have tatami reed mats, and in newer places you’ll usually find tile, wood, or rubberized flooring.
That’s not to say people in Japan can’t appreciate a nice bit of soft fuzziness between their toes, though. Even without permanent carpeting, many people will toss a carpeted mat on the floor to make their living or bedroom extra comfy, especially during the colder part of the year.
Of course, cold weather also means spending more time indoors, with extra time on your hands, and sometimes that patch of carpeting becomes a canvas for some seriously cool fan art.
