In ancient Japan, kitchens were an essential part of the household. While glass cabinet inserts were not used during this time, the Japanese had storage solutions in their kitchens. They used wooden cabinets, shelves, and ceramic jars to store their food items. The Japanese cuisine is known for its simplicity and emphasis on fresh ingredients. They used various cooking techniques such as grilling, steaming, and simmering. Rice, seafood, vegetables, and tofu were staple ingredients in their diet. The Japanese also had a strong cultural tradition of tea ceremonies and often used the kitchen as a space for preparing tea.
