Look, personally, I find some some of the stuff coming out of the mouths of certain Japanese politicians offensive. But really, do signs like this help?

And if you really must produce signs like that, at leave be clever about it and do it in a language Westerners (mostly) can’t read. Like these (presumably) employees of an Audi dealership in China, who posted on their shop a banner that read, “Even if all of China becomes a tomb, we must kill all the Japanese” and “Even if not a single blade of grass grows in China, we must recover the Diaoyu Islands.” On its Japanese site, Audi apologized for the incident, saying the sign had been taken down immediately and that it was unconfirmed whether the people involved were Audi employees.
