Never underestimate the ability of the entertainment industry to plumb the depths of bad taste, and don't make the mistake of thinking it's some new thing, either.
For example, the early TeeWee show This Was Your Life surprised one Reverend Kiyoshi Tanimoto with a mystery guest from his past: The guy who dropped the a-bomb on him! Surprise! This magic moment brought to you by Prell shampoo. Prell: It gives a girl's hair that radiantly alive look!
(H/T to Popehat.)
Edited to add:
Divemedic notes in comments that the Japanese have never apologized nor made reparations for their savagery at Nanking and numerous other places, but that fact is irrelevant to the point of this post.
As anybody's momma could tell you, that the Japanese behaved as animals during WWII does not excuse a lack of manners by an American TV show. I've got no problem nuking people to cinders in their beds, but using it to sell nail polish and embarrass an innocent man of the cloth on TV is just damned trashy and no-count.
