We are pleased to inform you that Kana Shinoda, Founder of CODE BLUE, participated in a roundtable discussion titled "Challenges and Measures for Strengthening Japan's Cyber Resilience" in the April issue of Japan Business Federation (Keidanren) Monthly, and the content has been published as an article.
■ Article Overview As cyberattacks targeting domestic critical infrastructure and companies have increased and become more sophisticated, the "Cyber Response Capability Enhancement Act" and related legislation were enacted in May 2025. This article discusses challenges and concrete measures that should be addressed through public-private collaboration to strengthen Japan's overall cyber resilience under the framework of "active cyber defense(Noudouteki cyber bougyo)."
■ Participants and Their Perspectives
・Yoichi Iida (Cabinet Cyber Official): From the government's perspective, he explained the objectives of active cyber defense under the new legislation and the importance of building a public-private ecosystem to prevent the system from becoming merely nominal.
・Nobuhiro Endo (Vice Chairman, Japan Business Federation): From the business community's standpoint, he proposed the necessity of overcoming vulnerabilities at the management level, implementing comprehensive measures throughout society including small and medium-sized enterprises, and developing human resources.
・Sachiko Hasumi (Head of Cybersecurity Department, Starbucks Coffee Japan): Drawing from field experience, she emphasized the importance of authority design and command and control systems during peacetime that support "human judgment" in addition to technology alone.
・Kana Shinoda (Founder, CODE BLUE): From an international human resource development perspective, she discussed the importance of collaboration transcending ministerial boundaries and fostering an enthusiastic community.
The article PDF is available on the Japan Business Federation's website (in Japanese). If you are interested, we encourage you to read it.
