Mitsui Sumitomo to Acquire Majority Stake in Time Machine Underwriters
Deal News | Jul 09, 2025 | Re-Insurance News
Mitsui Sumitomo Insurance (MSI), a subsidiary of MS&AD Insurance Group Holdings and a major player in the insurance sector, has announced a strategic move to acquire majority ownership in Time Machine Underwriters Co., Ltd. (TMU). TMU, established as Japan's first managing general agency specializing in Representation and Warranty (R&W) Insurance, is poised to become an asset for MSI due to its niche expertise. The acquisition is set for August 1, 2025, with plans for MSI to eventually own TMU in its entirety. This strategic acquisition will strengthen MSI’s capabilities both domestically and internationally, enhancing its ability to offer valuable insurance solutions. Furthermore, as MSI eyes a merger with Aioi Nissay Dowa Insurance Co., Ltd. by April 2027, the company is strategically aligning to bolster its R&W Insurance market strategy. The rise in M&A activity within Japan, often seen as a remedy to the lack of successors in family businesses and a means for growth, has bolstered demand for R&W insurance products that MSI and TMU collectively aim to address.
