> Japan : 127,435,000 / 453,312 (379,602 + 73,710) = 0,36% (0,3% + 0,06%)

First, you shouldn't use this stats as Japanese one. "453,312 (379,602 + 73,710)" is the grand total about the number of crimes IN Japan.

Second, you can know the stats of "Japanese +foreign nationals with permanent resident status" when you do subtraction from your reports, but you never know the real "Japanese only" number. As I wrote above, they want to hide it and don't release it. All the sources we ordinary citizens can get are some technical(but not governmental) reports/researches and sensational articles.
