How fat is fat in Japan and what is a "horse face"?

Question:

Also, what kind of people can be described as "looks like a crab"? (I saw this several times in books and movies)
"Horse face" I heard on Akira Kurosawa's movie "Sanjuro".
Fat thing is from YouTube video about an overweight salary-men who have to pay fines (or their companies have to) if their waist is more than 33 inches or so.

Answer:

This is a funny question lol.

you are fat, if you are too big for your height and age. fat is subjective. our government however has made a law that those employees in government agencies and some private companies that have more than 33 inches waistline shall be put in a proper diet, exercise and some education for a period of time. It does not mean, when a police saw you walking in the street with over 33 inch waistline, you'll be put to jail. no it's not, lol although that would be funny.

"looks like a crab"? I have never heard or used that yet lol. I have said someone though he looks like a shrimp. because his eyes are too far from each other. maybe that's how looks like a crab mean.

horse face, me and my friends used to say this to foreigners (white people) with long thin face that look like a horse. this can be use to anyone who has the same face (long and thin).
