What can they do? Go to war with China? They're really powerless, though I did notice that they put a counterfeit notice on their website. Unless China steps up and works to stop the counterfeiting, there's really very little a country like Japan could do. I'm not even sure the US has enough influence to do anything. Counterfeit aircraft hardware is big business, and a big problem. Very dangerous, and we can't even manage to stop that. Believe me, aircraft hardware is documented far better than a stupid soldering iron, but somehow counterfeits keep showing up.
