What, a whole country needs to be taken down a peg because a few idiots posed with imperial flags in a wartime srhine?
Common ultra-nationalist beliefs are fairly odious: e.g. Japan should be applauded for liberating much of East Asia from Western colonial powers, the 1946-1948 Tokyo War Crimes tribunals were illegitimate, and the killings by Imperial Japanese troops during the 1937 "Nanjing massacre" were exaggerated or fabricated.

As a not unrelated aside, nationalism is on the rise everywhere and if this doesn't change there will be new wars and possibly another (very) big one. I am personally freaked out very much by the rise of nationalism in the EU where I live. I'm not one to trivialise waving flags at a war memorial.
But- again, why does this indict the entire of Japan? Are all Japanese likely to go wave imperial flags at Meiji?
It's far from a "few idiots". The place is super controversial. A nice place, but super controversial, politically.
Like I say above, why do a few idiots waving flags at Meiji mean that _the entire country_ needs to be "taken down" like the OP says?
I stress that this is "Japan"- the whole of Japan. Not the idiots waving flags at Meiji. Are all Japanese nationalist assholes?
