None of this is really surprising at all knowing how deeply rooted Japan's long history of bias, animus and outright racism against its Asian neighbors is embedded into its culture.
Japan still worships the WWII kamikaze warriors at a Shinto shrine in Tokyo as national heroes. Japan has never come to grips with its criminal wartime past. Japan hardly makes
mention of Pearl Harbor in its school curriculum certainly never making genuine effort at reconciliation with its Asian WWII victims or offering a sincere national apology for its bestial WWII military occupation.
Even today Koreans and Chinese can not achieve full Japanese citizenship.
The problem is that the ruling party and its leaders still worships the war shrines. I mean, imagine if Germany chancellor went to a temple dedicated to worshipping Hitler.
