In Japan, since there is no central heating, there is a sincere attempt to warm the body from the stomach out. And since this is Asia, where the stomach is considered the body's Command Central, it bodes well to keep your stomach happy, and above all, warm.
There is plenty of warmth around, you just have to look for it. Most Japanese families, for example, could survive an entire winter with just a pot of "nabe" to keep them warm. This is because they know the art of coaxing warmth out of food.
Today, I am going to teach you how to turn Japanese food into central heating. Japanese readers may disagree with some of my suggestions, but that is merely because they don't understand how desperate a "gaijin" without central heating can be. After all, how could they understand? They are Japanese!
