Current Japanese attitudes over WW2

I'm well aware from "The Blue Lotus" and history about Japan's involvement in world war 2.

Now, I'm into all things oriental including anything Japanese(except what happened in WW2),so Ive always been wondering, what are the attitudes and views of Japanese people today about world war 2 and the real life events that "The Blue Lotus" is based on, were there actually some people in Japan who were opposed to the war and imperialist/militaristic practices of Japan at that time.

If any fellow Tintin aficionados can answer this, it would really help.

And while I'm on this subject, what is Tintin's popularity in Japan, concerting their treatment in "The Blue Lotus"

I have some Japanese friends. They're not Tintin fans but there are several Tintin shops in Japan. He's fairly popular there (although I imagine manga and anime take centre-stage).

I don't have any answer for your other question, sorry.
