11 in my neck of Tokyo. The last few nights have dipped below freezing, however. This probably isn't super weird for the time of year here, however. Going up to visit the inlaws for the end of the year, and it's currently 0 up there. Last year, I think we hit -15 whilst we were there, but this year it looks like the low is going to be freezing (which is rather warm for northeastern Japan in December).
