Are there any cases when the USA has increased democracy in the world on a lasting basis? Even within the country we see the current Republicans trying to smother democracy by denying voting rights to citizens and inciting an insurrection.
After all, you don't blame a nurse for all their dying patients if their specialty is palliative care; the counterfactual matters.
In Japan, a party with over 10% of the vote is surveilled as a criminal organization and it's leadership is thus being targeted 24/7 and prosecuted for anything remotely possible such as putting flyers in mailboxes, in order to disrupt the political process.
If it's a democracy, it's one of the weakest ones.
The system is now proven completely failed, but who can change the law is who benefited from the law.

You may refer 調査対象団体 but I can't find the 10% criteria. JCP is the only national party listed on the list for historical reason. I never heard that JCP member had prosecuted by posting mails. Other organizations are really worth to be surveilled. I don't think this is why democracy in Japan is not good.
