wikipeadia has an interesting reading on Japanese history textbook controversies.. It includes the following line
"Reflecting Japanese tendency towards self-favoring historical revisionism, historian 
Stephen E. Ambrose  noted that "The Japanese presentation of the war to its children runs  something like this: 'One day, for no reason we ever understood, the  Americans 
started dropping atomic bombs on us.'"
