In many families the mother stays at home. The mothers run the house cleaning, going to the market and looking after the kids. Sunday is the only time dads have to spend with their families. Japanese fathers work very long hours. They come home after the kids are in bed.
Japanese homes are small and have dividers to change the size of the rooms.
They have smooth mats called tatami covering the floor. You must take off your shoes before going in. They sleep on the floor at night on thick quilts called futons. They put them in a closet during the day. Rather sitting on chairs, Japanese people often sit on the floor on mats.
