Removing dependence on individual expertise — transforming Japan's incident response through technology and systematization.
Fundamentally transform Japan's incident response capabilities in cybersecurity.
Systematize incident response techniques and enable automation. By developing talent and achieving scale, we resolve the imbalance between cybercriminals and responders in Japan.
Securious Lab G.K. was established in 2026 by founder Yamada and colleagues, drawing on extensive DFIR experience. We aim to resolve Japan's critical shortage of incident response personnel and eliminate dependence on individual expertise.
Masahiro Yamada
Founder & CEO
A specialist in digital forensics & incident response (DFIR) and threat intelligence. Over more than 15 years, his career spans R&D of cyberattack-detection technology at Fujitsu; becoming the first Japanese incident response consultant at the global security vendor Mandiant (now Google); launching a threat-intelligence research team at a domestic startup; establishing the CSIRT at Mercari; and serving as Northeast Asia Director at the DFIR-focused vendor Blackpanda. From an era when the term "incident response" was not yet widely known, he handled numerous cyber incidents — including state-sponsored targeted attacks and ransomware — and came to recognize Japan's serious shortage of incident response talent and the over-reliance on individual expertise. He founded Securious Lab to address these challenges through the systematization and automation of incident response techniques.
Tatsuya Fukuda
Chief Branding Officer
Graduated early from Osaka University's Faculty of Engineering in three years at the top of his class, and completed a doctoral program at its Graduate School of Information Science and Technology. Studied as a visiting researcher at UC Davis. After researching "business applications of generative AI" in the R&D division of a major manufacturer, he contributed to web system development, startup founding support, and PR/branding. While running his own e-book publishing and corporate branding businesses, he supports Securious Lab.
Takanori Oikawa
Senior Strategic Advisor
After graduating from Waseda University's School of Science and Engineering, he completed a master's program there with research in data mining. At a major manufacturer's research lab, he engaged in R&D across frontier areas including privacy, cybersecurity, and AI security, then drove the commercialization strategy and real-world deployment of research in these fields. He is active across academia, including serving on the steering committee of the Information Processing Society of Japan's Special Interest Group on Computer Security (CSEC).
