If a political discussion about introducing an age verification law is enough to make you doubt, it’s probably not worth moving to Japan. But I hope you can widen your view beyond this particular issue and privacy and consider Japan and your whole situation.
Like @FranklyFlawless said it’s over when we stop resisting. I hope you will keep resisting. We still have time to fight pending age verification laws. We don’t yet know what damage the age verification agenda will cause, but perhaps people will still be able to use digital technologies at some level even if all the pending laws pass.
- Advocate for privacy as a concept, and its importance.
- Fight politically against the age verification agenda where you live and globally. Discuss the problem with the people you know or have influence over. Also support advocacy groups like EFF who are fighting against the age verification agenda.
- Avoid using software and services that comply, for instance Ageless, a noncompliant Debian-based operating system.
- Refuse to submit to age verification when requested.
- Give the Unix-ish 1970-01-01 if you are forced to disclose a birthdate. (post)
- If you’re a software or service provider, refuse to comply or exercise malicious compliance. If you have substantial market share, threaten governments that you will shut down or refuse to service its citizens if age verification laws pass.
- Work on new or existing projects that aim to subvert or circumvent the effects of age verification laws.
In another thread I listed broadly how operating systems could respond if age verification laws pass.
In the interests of resistance, you will probably be far more effective at resisting from where you live than resisting after migrating to Japan. Consider the costs of migrating to another country, restrictions imposed on foreigners in Japan, familiarity and personal connections of your current place of residence, knowing the local language etc.
