Japan protects children online very differently to the UK. (Shout out to red rose for the heads up - it was interesting.) While the UK Online Safety Act is driving biometric age verification and platform-based ID checks, Japan has taken another route: mobile carrier filtering enabled by default for under-18s, combined with parental control and digital literacy.
There is no nationwide social media ban in Japan. Instead, age controls typically sit at the telecom/SIM registration layer rather than at individual platforms.
In this video I explain:
• Japan’s 2008 Youth Internet Environment framework
• How mobile carriers determine age at SIM registration
• Why filtering is enabled by default for minors
• The parental opt-out (waiver) mechanism
• The privacy trade-offs compared to UK-style age verification
This isn’t “no regulation” — it’s a different regulatory architecture.

If you’re following UK Online Safety Act developments, this comparison shows that “protecting children online” does not automatically require biometric ID checks across platforms — but every model comes with trade-offs.
Let me know in the comments: would you prefer telecom-level filtering, or platform-based age verificatio
There numerous solutions to addressing child safety online that do not violate personal privacy. This is one example, there are others. Solving the problem when you want to address this specific problem isn’t difficult. But the reality is that all of these measures being pushed are not meant to provide real safety to children, but rather to be able to de-anonymize the internet, so governments can better identify “dissenters” (i.e. people who criticize Israel) and provide higher quality information to AI and online marketing firms.
Somehow everyone has forgotten about parental controls that have been apart of consumer grade home routers for years.
Parental controls are there specifically to help parents. These settings allow a parent to block everything online only allowing access to approved lists of websites, generaly done through a whitelist or approved websites.
What is missing at a government level is a “curation effort” of websites, similar to Libraries that classify books by genres and appropriate age levels.
I would propose a government fund where Librarians or similar organizations can start this effort, and make these lists easily accessible within routers for non tech individuals, together with local initiatives and programs for parents that have a interest to learn more.
For power users lists like these already exists curated by public individuals very similar to pihole block lists and whitelists.
This concept would be the most privacy respectful IMO giving parents the most power to parent, while respecting everyone else’s privacy online including children.
But somehow we all know this is not about “protecting the children”, but really about mass surveillance for the public at all age groups, and yet this topic keeps coming up.
I love the digital library idea. Sadly, given the state of the US we would see folks on the street going
“The govs online libraries make kids want to be trans” or something like that.
This doesn’t mean Japan is a good place to live in btw.
Fair. As a halfbreed myself I can say it’s awful if you are not Japanese.
They do have some really kickass laws though.
I’m 0% Japanese and can say that so far, aside from some annoying paperwork, it’s a bliss compared to the countries I used to live in before. Maybe the difference is that I didn’t expect people to truly love me behind their smiles and politeness. Just being friendly (as it is in 99% of cases here for me) is enough, and way above my experience in Europe when people jumped to being rude and sometimes hostile right after hearing my accent after trying to speak local language.
If it relies on SIM cards that means it doesn’t work at all with regular computers or when the device connects over WiFi, right? Seems kinda useless.
Of course, all age verification checks on the Internet are useless regardless but this Japanese method seems extra useless.
Yes, but controls on local WiFi networks does nothing if they use a SIM to bypass it. So both are needed. And then that doesn’t take into account public networks, so controls are needed there. It’s a layered approach.
It’s carrier level. Your isp could do the same with off the shelf decryption appliances. Basically you decrypt the traffic and block traffic that isn’t decrypted.
Are there any better countries we could use as examples in the future other than one where child porn and beastiality are still legal?
