Yesterday I came across a channel that films the kitchens in various restaurants in Osaka. It was mind boggling how much eggs are used in the Japanese cuisine, for lunch and dinner. I now have a new appreciation of what the Japanese eat, and it is not what we would call "healthy".
Just to make sure that it's not just Osaka, found other channels doing similar things and consumption of massive amounts of eggs was a common theme.
Lack of raw fish was another eye opener - an average American likely eats more raw fish than an average Japanese.
