Nazisploitation is the term for sadomasochistic images featuring Nazis for sensationalist effect. Do people use Japsploitation for similar featuring Japanese soldiers during WWII?
Very rarely. Possibly due to guilt over the internment of innocent Japanese-Americans during the war.

Asiansploitation also occured to me. Asiansploitation would incorporate scarely Japanese men with the wicked old Chinese commies of the 50s and 60s. Nope. asiansploitation is the name of a comedy group.
