I'm curious about online privacy in Japan because I wanna live there

Don’t feel bad for yourself because this is not your fault. There are some thing in life we can’t control and we should just learn to live with them. This doesn’t mean we shouldn’t resist, but mental health is top 1 and your privacy is second. Just calm down and remind yourself that you cannot control everything. Overthinking is just going to do things worse because you’re looking for the fifth leg of the cat as we say in Costa Rica, if you know what I mean.
