Our history
Mitsui Sumitomo Insurance was established in 2001 but our origins go back much further. "Mitsui” and “Sumitomo” were each formed more than 300 years ago and are still operating as business management groups with major influence in Japan and the rest of the world.
An enduring philosophy
Mitsui and Sumitomo achieved sustainable development over the long term by responsibly fulfilling their obligations to care for society and the environment, thus earning the trust of their many and varied stakeholders, including customers, employees and communities. This is the philosophy that still guides Mitsui Sumitomo Insurance today.

The Mitsui conglomerate began as a shop dealing in kimono fabrics called “Echigoya”. It was opened in 1673 by Takatoshi Mitsui, a merchant in Edo (now Tokyo).
With the aim of accommodating its customers’ needs, Echigoya introduced many innovative business practices. These included adopting over-the-counter-sales and the cash-and-carry system which were unheard of in Japan at the time. Furthermore, Mitsui used flyers and umbrellas printed with the shop's name to publicise his business.
Mitsui also focused on customer-centric business management and brand strategy, and sought to boost employee motivation and satisfaction through personality-oriented performance evaluations. These pioneering approaches laid the foundation for Mitsui’s subsequent success and prosperity.

Sumitomo prospered through diversification beyond copper into such commodities as yarns, fabrics, sugar and medicine.

The history of Sumitomo began in the 17th century when Masatomo Sumitomo opened a book and medicine shop in Kyoto. Sumitomo gradually diversified into copper mining and trading, banking and heavy industry.
In 1690, Sumitomo discovered the Besshi Copper Mine in Ehime Prefecture which turned out to be one of the largest copper mines in the world. This major discovery contributed significantly to Japan’s economic development. However, the mining operations also impacted the environment. To help reduce this, Sumitomo planted more than one million trees and even relocated the copper refinery to an uninhabited island.
Sumitomo’s approach of contributing to the development of national and regional economies while also addressing environmental issues sowed the seeds for our corporate social responsibility initiatives of today.
