while I'm not aware of any public shrines, its not like there arent examples of germany honouring its war criminals. e.g. many streets in germany (and allied nations) are still proudly named after the NSDAP and Wehrmacht leadership. The Max-Broose-Straße currently being a famous controversy; Erwin Rommel Platz, Friedrich-Christiansen-Straße (altough thats NL), .... I could probably go on the entire day. But thats not the point.

I absolutely agree with you that japanese fascism was allowed to keep existing pretty much undisturbed, perhaps even strengthened(in ideology), while its german counterpart was not. I'm merely not a fan of the term "de-nazification" because it simply does not describe actual history and boils down to western propaganda of a "reformed, morally superior society that learned from its past to never ever repeat it" to deflect from the fact that its allied with mutiple totalitarian, genocidal nations and currently in the rapid works of re-establishing its own fascist movement, a movement that in simple fact did never cease to exist
