Great article on SavvyTokyo that explains the Japanese language you will find on the average rice cooker in Japan. In case you were wondering, they are often much more complicated than the simple old-school “cook” and “warm” that you might be used to:
Love it or hate it, you can’t avoid rice while living in Japan. It’s the prime meal on every Japanese dinner, the best company to all your washoku favorites, and the nutrient-rich meal that can keep you full throughout the day. But how often do you find yourself frustrated at all these Japanese buttons your rice cooker at home has? Or end up using only the largest button, ignoring the rest because you can’t fully understand them?
Stuff like this is invaluable if you’re staying at an AirBnB or even a room that has small applicances like this in it.
