These aren't "tropes" they are real aspects of the culture. These cultural features do have an effect on how democracy works in Japan and how the government perceives and responds to the public reaction to certain events, especially in regards to the economy. I have not heard a single, not a single person say the administrators of the country are doing a bad job which is why we're in this mess, no, they just seem to talk like there is some external, mysterious force causing these issues. Now maybe people are
thinking differently, but when it comes to the democratic process, the public discourse is important and it's lacking.
I have personally only heard one, I repeat one person criticize a politician in my entire time being here, can you believe that? He was a politician himself :)
The only other time I remember there being some suspicion about politics was after Abe's assassination, there was some conspiracies going around about how Korea is running the government because of his affiliations with a Korean cult. Even then, everything I heard was radically civil.
If this stock market and currency collapse was in the USA, you could imagine the discourse around it right?
I'm sorry but there is a real stark difference between cultures and the effect it has on the democratic process and therefore the urgency in which a government would react to negative public opinion. In this case, In Japan the government is almost always siding with big business, because why not? What will happen? The LDP will be removed?
The government in Japan is practically authoritarian at this point, they have no opposition, they're not going to adapt very quickly for the sake of worrying about the polls. Also worth reading about is Japan's "online defamation laws" which are also pretty dystopian in my opinion.
