Japan's current government isn't the best lot of people for this to be happening under but it is happening because China is alienating its neighbors with hyper-aggressive territorial and economic claims that in some cases seem to amount almost to crypto-irredentism, not because Japan is nefariously courting all these other countries' dependency and favor.
Certainly China hasn't made itself the nicest of neighbors, but the rise of people like Ishihara makes me more worried about this returning:
japan isa democracy, in case tou did not notice. china is not.
