This is apparently weird even to Chinese people; an image of ramen with rice and roast dumplings on sides amounts to a ragebait to them(as well as to experts in cardiovascular systems), while it's nothing more than a common lunch menu to students and young workers in Japan.
But I digress - my point is, the real traditional Japanese meal is more like half a football worth of rice with vegetable flavored salt, quite unlike idealized modern interpretations thereof.
