The value of Berkshire’s new Japanese investment soars
Berkshire Hathaway’s latest investment in Japan is off to a strong start.
shares of Tokio Marine Holdings Shares of Berkshire’s National Indemnity soared more than 24% this week after Monday’s announcement that it would pay $1.8 billion for a roughly 2.5% stake in Japan’s oldest insurance company. Barron’s magazine calls the company “one of the best-run property and casualty insurance companies in the world.”
Berkshire’s new acquisitions now have a market value of about $2.3 billion.
The two companies will also collaborate in reinsurance and explore strategic investments around the world.
In a Tokio Marine news release, the company said Berkshire’s corporate culture and values are “closely aligned with our own.”
He added, “Importantly, this is not just a business alliance. Through this, we will establish a long-term strategic relationship based on stock ownership, which we believe will be a strong catalyst for medium- to long-term growth for both companies.”

Ajit Jain, Berkshire’s head of insurance, was quoted as saying, “We expect this strategic partnership to create attractive long-term opportunities for both organizations.”
Barron’s reported that Jain oversaw the investment and that “Warren Buffett, former CEO and current chairman of the board, was likely involved.”
“This deal shows that Berkshire’s ability to write insurance is undiminished, despite Buffett relinquishing his CEO role in favor of Greg Abel. This bodes well for Berkshire, given the importance of insurance to a $1 trillion market cap company.”
Tokio Marine issued new shares for Berkshire to buy. In order to prevent dilution of existing shareholders, the company plans to buy back the same amount of outstanding shares.
Berkshire will be allowed to increase its stake by just under 10% through open market purchases. Advancement to a higher level requires approval from Tokio Marine’s board of directors.
Insurance Business points out that Tokio Marine has spent more than $17 billion over the past 20 years on acquisitions in the United States, including Philadelphia Insurance Company and Delphi Insurance Group.
The company expects the new partnership “could accelerate its trajectory through Berkshire’s trading coverage and reinsurance capabilities.”
