Many Japanese houses were provided with Kamado until around 1950 and that was mainly made on a dirt floor connecting to the entrance because of preventing fire. But with the advent of gas cooking stove & rice cooker, houses having Kamado almost disappear.
But rice cooked with using Kamado is more delicious than that cooked with rice cooker and many electronics companies have developed rice cookers that can reproduce rice cooked with using Kamado. Miniaturized Kamado for one person is used for cooking Kamameshi[釜飯（かまめし）] and pot dishes even now.
