AI Security Firm CoWorker CEO Delivers Special Lecture at Tokai University

CoWorker Inc. (Headquarters: Shinjuku-ku, Tokyo; CEO: Kazuki Yamazato), a developer and provider of AI security solutions, announced that on Friday, April 24, 2026, CEO Kazuki Yamazato delivered a special lecture for the 'Theory of Information and Telecommunications Industry' class at Tokai University's School of Information and Telecommunication Engineering.

Under the theme 'Considering the Future of Entrepreneurship and Cybersecurity at the Intersection of Human History and AI,' the lecture addressed the impact of rapid AI evolution on society, industries, and careers. Yamazato discussed the ideal talent profile needed in the coming era and the critical importance of cybersecurity in the age of AI.

After graduating from Tokai University's Department of Physics, School of Science, Yamazato developed large-scale advertising systems at Yahoo! JAPAN and subsequently served as CTO at several startups. He founded CoWorker in 2019 and is currently advancing the development and provision of next-generation security services that combine AI with cybersecurity.

During the lecture, sharing his own career and entrepreneurial experiences, he conveyed a message to the students: 'What creates value in the AI era is not just the volume of knowledge, but the ability to discover issues, execute solutions, and build trust over time.'

## Lecture Theme: 'Considering the Future of Entrepreneurship and Cybersecurity at the Intersection of Human History and AI'

This special lecture provided a broad perspective on technological evolution—from the 7-million-year timeline of human history to the internet, social media, and AI—framing the modern era as a 'turning point on the scale of human history.'

Yamazato explained that while the proliferation of AI has democratized access to advanced intelligence and technology for individuals, it has simultaneously escalated the sophistication of cyberattacks, thereby increasing the importance of ethics, judgment, and safety for those utilizing AI.

## Talent Needed in the AI Era: 'Ability to Implement Technology Safely in Society'

As AI accelerates certain tasks such as writing code, gathering information, and conducting analysis, Yamazato outlined the types of human resources that will become increasingly valuable.

He emphasized the importance of professionals who go beyond merely operating technology; they must understand its possibilities and risks, connect it to societal challenges, and design and implement it safely.

Particularly in the cybersecurity domain, the evolution of generative AI has accelerated the speed and sophistication of offensive tactics. Consequently, defenders are required to adopt advanced AI for detection, analysis, and diagnostics. CoWorker is researching and developing a 'Security AI Agent'—where AI and human experts collaborate—aiming to build a security foundation adapted for the AI era across areas like vulnerability assessment, penetration testing, forensic analysis, and malware analysis.

For Yamazato, it was a valuable opportunity to speak to students at his alma mater, candidly sharing his transitions, setbacks, and decision-making processes from his student days to starting his own company.

## Comments

- Kazuki Yamazato, CEO, CoWorker Inc.
'I am deeply honored to have had the opportunity to speak to the students at my alma mater, Tokai University, in the 'Theory of Information and Telecommunications Industry' class. The evolution of AI is vastly expanding the power of technology and information available to individuals. However, the ability to consider what this power should be used for and how to implement it safely in society has become more crucial than ever. In this lecture, I shared not only insights on entrepreneurship and cybersecurity but also the trial-and-error experiences from my student days to the present. Rather than seeking the correct answer from the start, I hope students will take small actions, accumulate experiences, and find their own questions. CoWorker will continue to engage in developing technologies that support the social safety foundation of the AI era, as well as fostering next-generation talent and promoting industry-academia collaboration.'

'With the rapid development of AI, it is becoming increasingly important for students in the information and telecommunications field not only to learn the technology but also to consider its impact on society. Through Mr. Yamazato's career and entrepreneurial experiences, this lecture conveyed the importance of problem-discovery skills, execution ability, and trust in the AI era in very relatable terms for the students. In particular, his perspective on treating cybersecurity not merely as a specialized technical field but as a vital domain supporting the safety foundation of society as a whole provided a significant stimulus for our students. We intend to continue valuing opportunities that connect practical industry insights with university education.'
