Insurance broker Willis, part of WTW, is significantly expanding its team in Japan. The move highlights the firm’s strong commitment to the growing Japanese market.
In the first nine months of 2025, Willis hired 22 new professionals. These hires are part of a major expansion of its client-facing teams. The new roles are in key areas like Risk & Analytics, Facultative Reinsurance, Marine, Business Development, Large Accounts, and Claims.
This growth follows key appointments made in 2024 in Natural Resources, Construction, and Large Accounts.
Key Appointments Include:
- Kosuke Komorizono as Head of Risk & Analytics.
- Hisanori Nishizaki as Head of Facultative.
- Takashi Kato as Head of Marine.
- Yasumasa Kanie as Head of Claims for Japan.
The expansion targets a significant opportunity. Japan’s general insurance market is projected to grow from JPY 11.7 trillion ($81.1B) in 2024 to JPY 12.7 trillion ($93.9B) by 2028.
Ryohei (Roy) Nakazawa, Head of WTW Japan, explained the strategy. “Japan is one of the world’s largest insurance markets,” he said. “We are scaling up to drive better client outcomes.”
He cited growth in commercial lines, digital transformation, and risk advisory services. Businesses are also seeking more protection from climate change, cyber threats, and supply chain disruptions.
Nakazawa specifically noted the importance of marine insurance. Japan accounts for 11% of the world’s fleet of vessels, fueling demand for specialized cargo insurance.
The new team includes professionals recruited from leading firms like Marsh, Aon, Tokio Marine, and Mitsui Sumitomo.
“Our expanded expertise enables us to deliver best-in-class advice,” Nakazawa concluded. “We help clients navigate challenges and seize new opportunities with greater resilience.”
