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
