High suicide rate.
Practically the same in U.S. - 14.3 (Japan) vs. 13.7 (U.S.A.)
And Japanese still somehow have a reputation of having some crazy suicide rate.
Why not throw in murder rates in the mix as well - U.S.A. 5.3 vs Japan 0.2, in other words you're more than 26 more likely being murdered in U.S.A.
So, which one is the depressing one at the end of the day?
