2014 jap reported cases is 8,650 and the rate per 100,000 is 6.7
if we assume that an overwhelming majority of 95% of cases dont make it into the jap statistics for any reason

meanwhile in england and wales alone, the -reported- number of cases was 78,787 and the rate was 137.2. this becomes substantially higher after taking into account unreported cases even if you generously estimate that most of the cases are reported, if 50% are reported (unlikely) then the amount of cases becomes 157,574 and the rate would be 281 (based on 2011 combined census). this is before northern ireland and scotland are considered
so there is a massive gulf of difference between their rates even after including changes to the law since then
https://mainichi.jp/english/articles/20180719/p2a/00m/0na/015000cthe amount of reported rape cases rose, but it's not anywhere near enough to break even with the uk
all this shows is that japs have an underreporting problem, it doesn't mean it happens as often or more often there
