Stoves
The earliest dwellings in Japan used an open fire hearth for cooking. The first stove was recorded in the Kofun period, between the 3rd to 6th century. These stoves, called kamado, were typically made of clay and sand; they were fired through a hole in the front and had a hole in the top, into which a pot could be suspended from its rim. This type of stove remained in use for centuries to come, with only minor modifications. In the 14th century, in the Muromachi period, stoves with two holes were recorded in drawings. By the early 17th century, the beginning of the Edo period, large stoves with several cooking holes were common in the kitchens of the upper class house as well as in large restaurants. It is believed[by whom?] these multiple hole types appeared earlier than recorded but were omitted from drawings of the time because inclusion of a single hole stove was sufficient to indicate a kitchen. The stove was low, meaning cooks had to squat to cook. In the larger kitchens, especially those of palaces and temples, raised kamado that could be operated while standing up were developed in the Edo period (1603–1867).
Irori (囲炉裏) appeared in the Kofun period and served as a secondary stove. A section of wooden panels were removed from the floor and a lacquered square wooden frame was fitted in the place. The frame was filled with sand and an iron hook was lowered from the ceiling. Foods were reheated or cooked over in an iron pot hung from a hook and the fire served as a heat source. This type of stove became common in many homes by the early Nara period and a smaller irori is the center piece of a tea house.
A third type of stove, a hibachi (火鉢) lit. “fire pot”, appeared as late as the early Heian period but is likely to have been used earlier. A hibachi is a deep small pot half filled with sand and ash and a small fire was started in the pot. It was used as a safer form of heating equipment than was available previously and could be used to cook small morsels of food.
