Our story
Decarbonization is an immense undertaking. The global effort required is poised to spark the greatest capital reallocation in a century, requiring US$9.2 trillion in annual average spending on physical assets. Specialist insurance is critical to this. The risk transfer market must evolve, embedding stability and efficiency and reducing the volatility that has hindered progress.
At the core of Tokio Marine Group’s culture lies the belief that insurance has the power to solve the biggest problems of each era. This belief has driven the Group’s evolution for nearly 150 years and underpins our global growth.
