The new so-called "law" against insults isn't as dystopian as you think

While the whole world got worried about the new artificial “law” that bans insults, be reminded that Japan is only strict on paper, but in reality it’s like a dog barking out loud with no teeth to bite with.
Even if you don’t anonymize yourself, if you’re just saying something like “Kishida is an asshole” once on Shitter, but otherwise never appear in the mainstream media (and if you do, you’re not being painted as some kind of Adolf Hitler Jr. with a MAGA cap and a Russian ISIS flag), then I really doubt they’ll even bother with you.
Even in a country where police has barely anything to do, they’d rather spend their resources on something more important, like having lunch at Mr. Donuts.

Of course best is to keep yourself anonymous, because they WILL put up examples to keep the population in check.
These examples usually consist of state actors anyway, but what I do expect to happen (at least, I hope so) is that Japanese people become more privacy aware again.
Since the raise of Shitter, LINE, Instantkilograms, Discucked, JewTube, TickTock, and the rest of the evil platforms, the people here have completely forgotten to keep themselves up to date about privacy risks.
On the one hand everyone rightfully so hates it if you make photos of people’s faces without hiding them, and absolutely refuses to get a MyNumber card, because both are serious privacy concerns, but on the other hand they have absolutely no problem at all signing up on millions of services that require a valid phone number (and there are no pre-paid SIM cards with valid phone numbers here in Japan, mind you), and have certainly no problem doxxing themselves to JewTube for a 10 yen a year ad revenue, because “I have nothing to hide”.

So artificial “laws” like these will only make people more curious about privacy, and will turn to information on sites like テクニカル諏訪子 and アノニマスの見解 (I could say my website as well, but this site is entirely in English, so I don’t think they’ll use me as a reference) as well as domestically developed and hosted pro-privacy services at 076 AIB and Fedibird to guide them to more privacy, and more importantly, more anonymity.
So I can see light shining at the end of the dark tunnel, if the Chinese and Cubans are able to wake up, the Japanese eventually will too.
