The natural hot springs (onsen) and bathhouses (ofuro) are very popular in Japan. Japanese people always keep the toilet and the bathroom neat and clean. They keep it clean after using them for the convenience of the other users. Hot springs (onsen) are numerous in Japan, and for centuries the Japanese people have enjoyed hot spring bathing. Visits to hot spring resorts were hailed not only as a means of relaxation but also for the beneficial medicinal properties attributed to thermal spring water. Its water is taken directly from mountain, so it comes imbued with natural minerals from the volcanic area where the ocean is located. They are usually situated in mountain tourist areas, and the Ofuro is usually outdoors. Hot springs are still major attractions for vacationing Japan. Kitchen is one of the main parts of any house. Japanese kitchen is called Daidokoro. Traditional Japanese kitchens and cooking centered on the stove and the hearth. Food was cooked in pots over a kamado, a stove made of earth or clay. It functions much like a modern stove, except that it is heated by an open fire instead of gas or electricity. In old traditional houses the kitchen was different than now. Irori is the name of those Japanese traditional kitchens that were usually located in the center of the living room and were used for both cooking and also heating the house. In the center there is a jizaikagi or pothook, where you hang the cooking pot or kettle. While the irori was used for cooking, it also provided light to the room. Traditional Japanese cooking involves a lot of boiling, broiling, steaming, grilling and frying.
