Sleeping on the floor is a traditional practice in Japan that has both practical and cultural significance. Traditional Japanese homes were multi-purpose spaces, so furniture was designed to be lightweight and portable, such as futons that can easily be rolled up and stored away. Futons are the most common type of bedding used in Japan, placed directly on tatami mats made from woven rush grass over a straw base. Sleeping on the floor is viewed as a way to stay humble and grounded, maintain a connection with traditional life, reduce environmental impact, and improve health by promoting better blood circulation and posture. While some modern Japanese homes have adapted to Western-style beds, many people still prefer sleeping on the floor for its benefits.
