The limits are 33.5 inches for men, 35.4 inches for women.
To give you an idea of how strict that is...*I* barely miss the limit. (Well, if I suck in my stomach, I can pass, but I don't know if that'd be allowed.)
Those of you who have seen me lately can vouch for the fact that I'm not exactly overweight. Nor am I very large. You can gauge from my body shape what their standards require.
Glad I'm not Japanese. They'd be sending me out for mandatory counseling and monitoring.
