Sompo Holdings, Inc. is one of the three largest insurance groups in Japan, formed through the 2010 merger of Sompo Japan Insurance and Nipponkoa Insurance. Headquartered in Tokyo, the company operates across domestic property-casualty insurance, overseas insurance (through Sompo International), life insurance, and nursing care and healthcare businesses. Sompo manages an investment portfolio of approximately $80 billion.
Investment Strategy
Sompo’s investment portfolio has been undergoing a strategic transformation as the company reduces its traditional Japanese cross-shareholdings and reallocates capital toward a more diversified global portfolio. Historically, Japanese insurers maintained large positions in the equities of business partners, but Sompo has been steadily selling down these holdings and redeploying the proceeds into foreign bonds, alternative assets, and other return-generating strategies.
The core fixed income portfolio includes substantial Japanese government bond holdings matched to yen-denominated insurance liabilities, alongside a growing allocation to foreign government and corporate bonds. The international portfolio, managed through Sompo International’s operations in the US and Bermuda, is invested in US investment-grade bonds, structured products, and alternative assets aligned with its reinsurance and specialty insurance liabilities. The investment team manages currency exposure across the group’s global operations.
Private Markets Approach
Sompo allocates approximately 7% of its investment portfolio to alternative assets, including private equity, real estate, infrastructure, and hedge funds. The alternatives program has expanded significantly in recent years as cross-shareholding reduction has freed capital for reallocation.
Private equity investments include fund commitments to managers across the United States, Europe, and Asia. Sompo has been building its GP relationships and increasing commitment pacing to establish a diversified portfolio across vintage years and strategies. The company invests primarily in buyout and growth equity strategies, with selective exposure to venture capital and special situations.
Real estate investments span Japanese domestic properties and international real estate funds, providing geographic diversification and income stability. Infrastructure investments have become a strategic priority, with Sompo attracted to the stable, regulated cash flows that align well with its insurance liabilities. The company invests in core infrastructure assets across energy, utilities, and transportation.
Hedge fund investments provide portfolio diversification and non-correlated returns, managed through a diversified allocation across multiple strategies. Sompo’s overall approach to alternatives reflects a deliberate multi-year transition toward a more globally diversified and return-oriented investment portfolio, consistent with the company’s medium-term business plan.

Sompo invests in private equity, real estate, infrastructure, and hedge funds. The company's alternatives program has grown as part of its strategic effort to diversify returns beyond Japanese domestic bonds and cross-shareholdings.
How has Sompo's international expansion influenced its investment portfolio?
Sompo's acquisition of Endurance Specialty Holdings (now Sompo International) in 2017 added significant US and Bermuda-based insurance operations. This has broadened the company's investment portfolio geographically and increased exposure to US fixed income and alternative asset markets.
What is Sompo's approach to reducing cross-shareholdings?
Like other major Japanese insurers, Sompo has been systematically reducing its cross-shareholdings in Japanese equities. Proceeds from these sales are being redeployed into higher-returning and more diversified assets, including foreign bonds, private equity, and other alternatives.
