To combat this growing threat, Japan’s Ministry of Internal Affairs and Communications collaborated with NICT (National Institute of Information and Communications Technology) to launch the NOTICE Project. Telecommunication companies now scan networks to identify vulnerable IoT devices and notify users to strengthen their security.
Japan has also revised laws to allow proactive monitoring of devices at risk of unauthorized access—a rare national-level initiative. However, experts agree that technology alone cannot solve the issue. User awareness and responsibility remain critical.
What You Should Do to Protect Your IoT Devices
Here are simple steps that anyone can take:
✅ Change default passwords immediately
✅ Use strong, unique passwords for each device
✅ Update firmware regularly to fix security vulnerabilities
✅ Turn off unnecessary remote access features
✅ Enable two-factor authentication (2FA) if available
Even one unsecured device in your home can become an entry point for hackers.
Expert View: Why This Matters for the Future of Autonomous Cars
The automotive industry is rapidly integrating IoT technologies. Since 2024, strict cybersecurity standards for vehicles have been enforced globally, requiring secure hardware, software, and protection against hacking.
As autonomous driving evolves, vehicles will rely heavily on IoT data—from traffic sensors to communication with surrounding infrastructure. But if IoT systems remain vulnerable, self-driving cars could be hacked through external networks, threatening safety on the road.
Simply put, the future of autonomous mobility depends on securing IoT.
Without cybersecurity, a “smart society” cannot exist.
Final Thoughts
Japan is admired for its advanced technology, yet the issue of unsecured IoT devices reveals a hidden weakness. While government initiatives like NOTICE are making progress, the responsibility ultimately lies with each user. IoT devices are convenient—but they must be used with caution.
As we move toward a fully connected society, including smart homes, smart cities, and smart mobility, cybersecurity awareness is no longer optional—it is essential.
