with other cuisines. Kitchens were completely reorganized to cook these foods; kitchens of the Edo period were used for simple menus of rice, broiled fish, vegetable soup, and pickled vegetables. The first gas light was installed in Yokohama by 1873, but it would be more than 30 years before advertisements for the gas started appearing in newspapers. These ads were not directed at middle to lower classes. In the 1908 study of how gas was used in Tokyo, 57% was for lighting, 14% was for fuel, 19% was for powering motors, and 3% was for streetlights. This meant that gas was used to light only 1 out of 9 households and only 1 out of 100 households used gas for cooking. Gas companies realized this, and early appliances were directly imported from England which made them too costly for all but the richest citizens. The Japanese kitchen turned away from American and European kitchens at this point. The first item of the industrialization to be introduced to most houses was the gas-heated rice cooker. A gas stove were introduced much later as the cost of gas was still too high for most homes. A gas oven, often an essential part of the kitchen in many American and European houses, never made it into most Japanese households because dishes requiring cooking in an oven, such as roasted chicken and baked pies, became popular only much later. Instead of an oven, a smaller fish oven was fitted into a gas stove. The gas-heated rice cooker remained in use until the 1970s in many houses and was eventually be replaced by the electric rice cooker. In the 1920s, electricity became more widespread in homes in Japan. In Nihonkatei daihyakkajiten (literally Encyclopedia of Japanese Household) published in 1927, there is already an entry of "katei denka" meaning a completely electric house. It says, The most important reason to use electricity for all needs of a house, lighting, heat, power is because it will help women to work, increasing their efficiency, make living easier and comfortable, and also make it economical. There must be several electrical outlets in each room to easily use an appliance like electric heater. They also let occupants use electric light at any time and no one can forget the comfort of using appliances like an electric fan, an electric heater, an electric toaster, a coffee maker, an electric iron, and
