The bulking up of asset management overseas by Japan's largest private-sector life insurer comes as the nation's insurers are increasingly shifting money away from Japanese government bonds (JGBs), their main investment, into riskier but higher-yielding ones such as foreign corporate bonds to diversify their returns. Insurers in Japan have been hurt by diminishing investment returns after the Bank of Japan launched aggressive monetary easing in April 2013. In December, Nippon Life announced a deal to acquire 24.75 percent of TCW from private equity firm Carlyle Group LP. Nippon Life has about 74 trillion yen ($653.25 billion) in assets. Tsutsui said potential targets are likely to be asset management companies with bond investment expertise, as the insurer's portfolio has been traditionally made up of fixed-income products.
He also said the company is looking for specialists in alternative investments, whose real estate and other portfolios offer diversification from conventional bond and stock investments. "As we have to diversify investment assets globally, alternative is a very important field," he said. "The United States has a very big and deep market for asset management. There are huge companies but there are also small but unique boutiques. We would like to keep looking there," he said.
