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.Sources:

Let me know in the comments: would you prefer telecom-level filtering, or platform-based age verificatio


All three of the points you list are true in the UK too.
Many UK ISPs and mobile providers will even filter out adult content by default (even for accounts owned by adults) and require you to opt-in to access adult content.
And yet despite this fact, the UK government is still pushing for age verification performed by websites (or the third parties they partner with) when the infrastructure is already there to do the filtering at the ISP level based on who owns the contract.
Now, tell UK citizens to host WiMax routers in a mesh network with default E2EE at every business, public building, and at home, and see how they react.
In Japan, I get sent to prison or “out to the sea” for even suggesting public infrastructure.
