A country that gives a shit about its constitution? Surely some mistake...
Through redistricting (or lack thereof), the Japanese electoral map disproportionately favours rural voters over urban residents (up to 5:1), reaching a limit explicitly forbidden by the Japanese constitution.
Because they couldn't come to a redistricting agreement that pleased them (and because that imbalance heavily favoured them), the party in power did call a new Diet election anyway, which was unambiguously called unconstitutional by all parties involved: members of the Japanese SC testified to it, nobody tried to argue otherwise. The election went ahead, the elected MPs have taken their seats and the current prime minister's legitimacy is not in any way questioned by anybody outside of some very limited constitutional scholar circles.
Oh yea: 6 month later, the Supreme Court is finally due to give out an official decision on the matter (not so much on whether the election was unconstitutional, as to what should be done about it), with legal commentators generally agreeing that whatever they decide, probably won't be enforced anyway.
It just means that it takes a few generations for a culture that was smacked down to rise back up
Pro tip: if you have to assure your readership that you are not racist, not once, not twice, but three times in the course of your post, that's generally not a good sign.
