Japan also has a huge issue with people admitting to crimes they did not commit. https://www.france24.com/en/20181207-japan-justice-99-system...

"Japan's official murder rate is widely believed to be significantly underreported"
in response to someone noting that Norway's murder rate is 2.5x Japan's murder rate.
None of the articles you linked to even mentions an elevated or misreported murder rate. Instead you linked to articles suggesting that sex crimes are underreported. Sex crimes are actually underreported in just about every industrialized country, US included.
Given that the official murder statistics are what they are, citation is still required
Norway was has a murder rate 2.5x that of Japan[1]. Norway is considerably less safe than Japan, albeit still very safe by global standards.
