HDI Global, an international insurance company specializing in servicing commercial and industrial clients, has appointed Hiro Yamasaki as Managing Director and Legal Representative of its Japan branch.
The appointment is in line with the insurer’s wider regional growth strategy and reinforces its commitment to disciplined underwriting, sustainable growth and strong partnerships with clients and brokers.
The insurer believes his proven track record of rigorous underwriting, cross-cultural leadership and sustainable growth will support HDI Global Japan’s next phase of growth.
Yamasaki has more than 25 years of experience in commercial property and casualty underwriting, portfolio management and international leadership.
He has held senior roles in Japan and the United States, leading large-scale underwriting programs and managing natural catastrophe (natcat) risk across the group.
Most recently, Yamasaki served in the global corporate underwriting function, driving underwriting enhancement, nacat exposure optimization, and advanced AI strategies in underwriting.
David Hullin, member of the Executive Committee of HDI Global, commented on the appointment: “Japan is an important market for HDI Global and strengthening our leadership team is an important step in our growth strategy.
“Hiro brings deep technical expertise and international experience that perfectly complements our disciplined underwriting approach. His appointment underscores our commitment to sustainable, profitable growth and being a transformation partner to clients and brokers in Japan.”
Yamasaki added: “I am honored to join HDI Global and excited to work with our talented Japan team. My focus will be on disciplined and sustainable growth, built on underwriting excellence, clear communication and strong partnerships with brokers and clients. HDI has strong momentum in Japan and I look forward to contributing to the next chapter of growth together with the team.”
Casey Sandler, who has successfully managed the Japan branch on an interim basis since August 1, 2025, has decided to continue his career outside the company.
Hullin concluded: “We would like to thank Casey for his dedication and valuable contributions he has made in his various roles at HDI Global Japan. His leadership has strengthened our position in this dynamic market. We regret his departure and wish him all the best in the future.”
