TOKYO - Tokio Marine Holdings Inc. said Monday that U.S. investment company Berkshire Hathaway Inc. will take a roughly 2.5 percent stake in the major Japanese nonlife insurer in a capital partnership.
The deal, estimated to be worth 287.4 billion yen ($1.8 billion), is expected to help Tokio Marine expand its overseas businesses, an area viewed as having significant growth potential.
Berkshire Hathaway, best known for having been led by the legendary investor Warren Buffett, will make the investment through National Indemnity Company, a wholly owned reinsurance subsidiary.
Under the tie-up, Tokio Marine and Berkshire Hathaway will collaborate when the Japanese property and casualty insurer conducts mergers and acquisitions for overseas insurance companies and related firms.
They are also expected to work together in the reinsurance business at a time when nonlife insurers are feeling their profits squeezed amid an increase in serious natural disasters.
In Japan, Berkshire Hathaway has invested in major trading houses. At the end of 2025, it had stakes of around 10 percent each in Mitsubishi Corp., Mitsui & Co. and Itochu Corp., according to an annual report compiled by the U.S. investment company.
