Mitsui Sumitomo Insurance Company, Limited is one of the core operating companies within the MS&AD Insurance Group. Our mission is to contribute to the development of a vibrant society and help secure a sound future for the earth by bringing safety and security through the global insurance and financial services business.
Regarding a “resilient and sustainable society” as the image of society that the Group is aiming for in 2030, we will seek to achieve it by developing the story of value creation of MS&AD as a Group-wide initiative.

To achieve a resilient and sustainable society, it is even more essential that it continues creating shared value (CSV) through corporated activities. We have incorporated the SDGs in the Medium-Term Management Plan “ Vision 2021” as milestones to CSV. Key strategies in the “Vision 2021” are to pursue group’s comprehensive strengths, to promote digitalization and to reform portfolio.
We believe our raison d’être is to provide security and safety, and to contribute to society through our insurance business. As risk professionals, we will continue our efforts to resolve various social issues by working to reduce traffic accidents, improving preparations for large-scale natural disasters, and promoting the dissemination of renewable energy.
We will continue to fulfill our raison d’être with integrity and a sense of speed in order to further gain the trust of our customers and support social development.


Mitsui Sumitomo Insurance Company, Limited was formed in October 2001 through a merger between the former Mitsui Marine & Fire Insurance Co., Ltd.(“Mitsui Marine”) and the former The Sumitomo Marine & Fire Insurance Co., Ltd. (“Sumitomo Marine”).
Mitsui Marine and Sumitomo Marine were leading non-life insurance companies boasting long histories, having been established in 1918 and 1893, respectively.
In April 2008, the entire group transitioned to a holding company structure for the purpose of engaging in more advanced business diversification. In April 2010, the Mitsui Sumitomo Insurance Group, Aioi Insurance Co., Ltd. and Nissay Dowa General Insurance Co., Ltd. merged to form the MS&AD Insurance Group.
