Comprehensive Seminar on Ransomware Threats and Countermeasures

Tsuji & Hongo Tax Corporation, headquartered in Shinjuku, Tokyo, and led by Chairwoman Koeko Kuwaki, is partnering with Tsuji & Hongo IT Consulting Co., Ltd. from Shibuya, Tokyo, under the leadership of President Ken Kurohita, to present a crucial seminar titled "Comprehensive Seminar on the Latest Ransomware Threats and Countermeasures" on November 28, 2025. As ransomware attacks have surged, they are no longer an issue confined to IT departments but have evolved into significant business risks impacting the survival of organizations. Thus, all companies find themselves compelled to adopt effective countermeasures.

During this seminar, we will carefully cover the fundamentals of ransomware, examine new and serious case studies of damage caused by attacks, and outline how these infections occur. We will emphasize protocols surrounding people and systems, explaining how to implement these defenses in an easily accessible manner, even for those with no prior knowledge of security issues. Additionally, we will delve into the supply chain assessment system initiated by the Ministry of Economy, Trade, and Industry set to launch next fiscal year.
