No he should not, Commando. While the US government did a stellar job of concealing it and remaking his image as a pacifist, Hirohito was very strongly involved in WW2 and very much on top of what was going on with the war. Though the US may see him as some sort of patron saint of Japan, most countries (particularly the ones that suffered greatly at the hands of the Japanese in WW2) see him as having been a war criminal. Which he was, of course, but it was far more convenient for the US to leave him alive and a figurehead than to execute him and risk turning all of Japan against the US. Politics are messy, to say the least.
If you want an in-depth look at Hirohito's life, as well as some pretty detailed accounts of his war presence, you should check out The People's Emperor by Kenneth Ruoff. The writing style is academic (meaning a bit of a dry read), but the book is very informative.
