The workplace is evolving faster than most IT security frameworks can keep up with. Agentic AI—autonomous AI systems capable of making decisions and executing tasks without constant human oversight—is no longer a futuristic concept. It's here, and it's already being used by your employees today. According to Gartner, over 57% of employees use personal generative AI accounts for work purposes, and 33% admit to inputting sensitive information into unapproved tools. This poses significant security risks that Japanese businesses cannot afford to ignore.
Unlike traditional AI tools that respond to prompts, agentic AI can autonomously plan, execute, and adapt its actions based on changing environments. These AI agents can schedule meetings, draft emails, analyze data, and even make decisions about business processes—all without human intervention. While this boosts productivity, it also creates new attack surfaces that cybercriminals are increasingly targeting.
Employees are increasingly adopting no-code and low-code AI platforms to automate their workflows. While this drives innovation, it also means AI agents are operating outside IT's visibility. Unsecured code, unchecked permissions, and unauthorized data access become common vulnerabilities. Japanese companies, particularly those handling sensitive customer data, must address this shadow AI problem before it leads to compliance violations or data breaches.
Japan's APPI (Act on Protection of Personal Information) imposes strict requirements on how personal data is handled. When employees use unauthorized AI tools, they may inadvertently transfer sensitive data to servers outside Japan, violating data localization requirements. With global regulatory volatility increasing, Japanese businesses face growing pressure to formalize AI governance and demonstrate compliance to regulators and stakeholders.
The good news is that Japanese businesses can turn AI security challenges into competitive advantages. Here's a practical approach to managing agentic AI risks:
Start by identifying all AI tools and agents currently in use across your organization. This includes both sanctioned enterprise tools and personal accounts employees may be using. A comprehensive inventory helps you understand your exposure and prioritize security measures.
Create explicit guidelines defining which AI tools are approved, what data can be input, and how employees should report suspicious AI activity. Policies should address both security and compliance requirements, aligning with APPI and industry-specific regulations. Make sure these policies are communicated in both English and Japanese to ensure full understanding across diverse teams.
Traditional IAM strategies weren't designed for autonomous AI actors. Adapt your access controls to register, authenticate, and govern AI agents just as you would human users. This includes credential automation, policy-driven authorization, and continuous monitoring of AI activities.
Traditional annual security awareness training is no longer sufficient. Gartner recommends moving toward adaptive behavioral programs that address AI-specific risks. This means regular, scenario-based training that evolves with the threat landscape—and ensuring employees understand the unique risks of agentic AI.
Many Japanese small and medium businesses assume AI security is only a concern for large corporations. However, the opposite is true. SMBs often have fewer IT resources, less sophisticated security controls, and a higher reliance on employee vigilance. A single data breach involving customer information can devastate trust and incur significant penalties under APPI. By implementing proper AI governance now, Japanese SMBs can protect their reputation, ensure compliance, and position themselves as trustworthy partners for larger enterprises.
