And after a while, I remember my parents bought Gasu-kama which uses Gas. In UK, some Japanese restaurants still use this type of rice cookers. The quality of rice is better cooking with this type of rice cooker than electric rice cookers.
This is the latest type of rice cooker we use in Japan nowadays.
It is electric, and has got a timer so that we could set the time we would like the rice ready and we set it usually for breakfast and dinner time, and expensive type of rice cookers cook brown rice etc.
