No. Japan is very anti commie and hasn't had a total left wing government since the 90s. Even when the LDP isn't in power it's always the majority in their diet system of governance and as a matter of fact, the last election Abe got the youth vote of those under 30 who do vote. They ARE subject to the whims of the USA since they relied on their protection since the end of WW2 and their populace is so passivist they can't get article 9 repealed or amended without a massive backlash, which was by design of course at the behest of the US government to make sure they never decide to invade anyone again, though they did check China's saber rattling and said they would back Taiwan if China invaded. Japan is essentially the US's man on the inside in Asia and the 2nd most powerful navy in Asia next to China so they DO have some leeway and can make the US concede some things if they want to use them and their navy....quid pro quo type of deals when needed.
