I was actually surprised by this. At least in hotels (specially in the traditional "ryokans"), the Japanese breakfast consists of some sort of fish (normally grilled), rice, some small bites (mostly for flavor) of seaweeds and some soup or another. I have no idea what people eat at home, but all in all it's not a terrible way to start your day (once you get over not having a bunch of sweet stuff.)
