Japan's war crimes (The Rape of Nanking, The Manila Massacre, Unit 731, etc) have been covered in exhausting detail. Unless the stories about the airmen introduced somethingnew or unique, the age of the story, the fact that the majority of its participants are now deceased, coupled with the fact Japan has been an American ally since the Korean War more than 60 year ago means that the story has no legs.
WWII contained a number of atrocities committed by all sides. As the majority of its combatants die, most of those horrors will be forgotten and the world will move past was has happened. There are books and documentaries which relate the tales, but to expect there to be any punishment or accountability decades after the affair has ended seems to misunderstand how quickly human being adapt themselves to new realities.
