First time I went to Tokyo about 17 years ago, I specifically went shopping for the most expensive rice cooker. At that time, being dink’s, it would have been a fun souvenir. What I ultimately discovered as the most expensive rice cooker in the highest end department stores at that time, was a rice cooker made by Mitsubishi, where the cooking bowl was a machined chunk of graphite. Ultimately I wasn’t confident it would work in the US without a huge transformer, so I opted against it. Ended up buying a National (Panasonic) which has served me for over 15 years. Loved it so much, that I started giving them as wedding presents. Only one couple asked to exchange it… they’re divorced. Maybe a sweet rice cooker would have saved their marriage.
