In ancient Japan, kitchens were an essential part of daily life, and some incorporated a built-in steam room known as a 'mushi-buro.' These steam rooms were used for cooking, as well as for bathing and relaxation. The ancient Japanese believed that steam had purifying properties and used it for various purposes. The mushi-buro in ancient Japanese kitchens were typically made of wood and featured a system that produced steam. The steam would then be used for cooking, particularly for steaming rice, vegetables, and seafood. It was believed that steaming helped retain the natural flavors and textures of the food. The steam rooms also served as a place for relaxation and rejuvenation, with the steam believed to have therapeutic effects. People would often spend time in the mushi-buro, enjoying the warmth and steam while taking care of their physical and mental well-being.
