Japan won't survive what China has in store for them if they're 'pacifist', simple as that. Japan needs a real military again. Ultimately, it needs nukes, but they'll have a massive internal struggle to overcome in regards to that.

China has Nukes, and China hates their guts (pretty fucking justifiably, too) for their unprovoked crimes in Nanking and Manchuria.

If Japan is not seriously re-armed by the time Chinese air and navy capabilities start to challenge US dominance, they'll be conquered, and the way the Chinese will treat them will erase any complaint about the US that Japanese ultranationalists ever had.
