Honestly a lot of my Japanese friends are mostly just disengaged with politics. Its considered taboo to discuss with people so its hard to convert people among friends until you know they're ok with it . Even when they want to talk about it, I have several friends who have told me its refreshing to be able to discuss Japanese politics with someone because it's so ...almost cringe to talk about it normally. Couple that with a government that seemingly never enacts meaningful change and participation and education is waaaaaay down.
I have a couple friends who voted for Takaiichi and all of them just gave superficial reasons like that shes "cool". Online is different from reality always.
