This is not a good or evil situation. its a Political, territorial issue
Of course.
But still, it is a bad look when they are basically caught in this position where they're asking China to withdraw evidence of JASDF doing the same thing Japan condemned the PLAAF for doing, making them look like filthy hypocrites.
Frankly I think they could've let this thing slide into obscurity after China released their own footage, rather than histrionically saying China should remove their video off their government website (!!).
Hell, I wonder why they even bothered to make the original PLAAF interception a headline in the first place. They know the PLAAF interception wasn't particularly different to any other interception in the world, and they must have known that China would have its own footage of JASDF reciprocating. So trying to score a few low hanging PR points among those in the world who know nothing about military fundamentals, with the dangerous of making themselves look like hypocrites, seems like a needlessly high risk move.
Unless they're that desperate for some bad PR for China...
