It’s amazing that we’re still building memorials to the Nazi’s victims, but few people even know what the japs did.

Agreed.  You (and others) may find this FR thread interesting, although incredibly saddening.

Beheaded at whim and worked to death Japan's repugnant treatment of Allied PoWs

How about the germ warfare that’s still killing people in Asia?

Please forgive my ignorance; I'm not sure that I'm familiar with what you're referring to.  Do you mean germ warfare munitions from WW2?

[ozzymandus]

Yes. The Japs used anthrax and other types of germ warfare in China and other countries. Some of the cultures they released are still active. There was a show about this on the History Channel.

Unit 731 - Manchuria. A Japanese bio warfare unit that released plague infested rats, fleas, cholera and all sorts of other stuff in China. they also practiced vivisection and other “medical experiments” [freezing z prisoner’s arm by pouring water on it, then snapping it off; tying prisoners to stakes and dropping artillery in to see schrapnel patterns, and gangrene, etc]
