Kerosene. Japan is big on kerosene. Almost all of the portable heaters are kerosene. This is the first one I bought 17-18 years ago. Unlike some, it isn’t electrically run so it’s good to keep in case the power goes out… or there is an earthquake.
Setsubun. February 3rd is the day we throw roasted soy beans out the doors and windows and say, “oni wa soto!” (demons be gone!), and throw beans inside and say, “fuku wa uchi!” (fortune come in!). Then you collect and eat the number of beans that represents your age.
