Introduction to Online Safety Education: Protecting Children from Harm on the Internet

In 2023, 139 elementary school students in Japan fell victim to crimes that originated on social media — a record high in the history of police statistics. According to the National Police Agency, this represents an increase of 25 children compared to the previous year, and is more than three times the figure recorded a decade ago. The spread of smartphones among younger and younger age groups lies directly behind this trend: a reality in which even first and second graders routinely use SNS means that the assumption "we'll teach internet safety when they reach middle school" is no longer tenable.

"Don't Talk to Strangers Online" Is No Longer Enough

Traditional internet safety education focused on behavioral rules: "don't talk to strangers," "never share personal information." But the risks children face today have a structure that simple rules cannot address. Cases frequently involve someone who was first encountered as a gaming opponent and gradually built what felt like a genuine friendship before an offense occurred, or who exploited a child's desire for followers and approval. The tactics used by offenders have grown more sophisticated, matching the actual behavioral patterns of children. Because the design of SNS platforms actively encourages connection, the pathways through which children can be exposed to risk are wide-ranging.

Three Pillars of Protection: Technology, Dialogue, and Environment

Effective online safety education cannot rest on technical restrictions alone, nor on memorized rules alone. Drawing together insights from researchers and educational institutions, effective approaches combine three elements: technology, dialogue, and environment.

On the technology side, configuring content filtering is a minimum baseline. The fact that roughly 90% of child victims had no filtering active shows that many households have yet to set it up. That said, filtering is not foolproof — in-game chat functions in apps, for example, provide routes around it. On the dialogue side, building everyday relationships in which a child feels comfortable saying "something strange happened" is critical; when children find it hard to report incidents, early detection is delayed. On the environment side, physical measures such as limiting device use to shared spaces like the living room serve as a meaningful deterrent.

Toward Education That Explains "Why It's Dangerous"

Telling a child "don't post photos online" without explanation leaves them following a rule they don't understand — and likely breaking it in spaces adults can't see. What works is explaining how things actually function. Telling a child, in terms they can grasp, that "photos contain metadata including the location where they were taken" or that "once an image is sent, the recipient can save and share it" builds the ability to judge situations independently. The Ministry of Education's 2024 revised guidelines also emphasize the cultivation of critical thinking as part of "information utilization ability" — moving beyond mere literacy.

Online Safety Education Is Not About Fear

When adults emphasize only the dangers of the internet, children come to feel that "if I mention something online to a grown-up, they'll take away my device" — and they hide problems instead of reporting them. The goal of online safety education is not to push children away from the internet, but to equip them with the judgment to protect themselves while using it effectively. At Digital Kodomo BASE, we provide hands-on learning experiences in Ota Ward that help children develop both familiarity with technology and a clear understanding of safety. Building technical fluency and safety awareness together is what digital education for this era must look like.
