HQ Function

The headquarters serves as the strategic command center for the Sompo Group, overseeing global operations, corporate governance, financial strategy, risk management, and group-wide digital transformation initiatives.

Notable Features:

The Sompo Japan Head Office Building, where the HQ is located, is an iconic skyscraper in Shinjuku, recognized for its distinctive curved facade. Designed by Yoshikazu Uchida and completed in 1976, it also houses the Seiji Togo Memorial Sompo Museum of Art, making art accessible to the public.

Work Culture:

The HQ fosters a professional, disciplined, and increasingly globally-minded work environment. It emphasizes collaboration, innovation in response to societal changes (like an aging population), and a strong commitment to customer service and ethical conduct, blending traditional Japanese corporate values with a modern, international outlook.

HQ Significance:

The Tokyo headquarters symbolizes Sompo's deep roots and leadership in the Japanese market, while also being the hub for its expanding global ambitions. It is central to decision-making that impacts its extensive network of companies and services worldwide.

Values Reflected in HQ: The headquarters' prominent and enduring presence reflects Sompo's values of stability, reliability, and long-term commitment. The integration of an art museum also suggests a broader commitment to culture, community enrichment, and societal well-being beyond core business operations.

Location:

Sompo Holdings maintains a robust global presence, operating in over 30 countries and regions worldwide. Key functions supported globally include property & casualty insurance (both personal and commercial lines), life insurance, specialty insurance and reinsurance (through its Sompo International platform), and an expanding portfolio of nursing care, dementia support, and digital healthcare services. This international network allows Sompo to cater to diverse customer needs, manage risks effectively on a global scale, and drive innovation across its core business areas, with significant operational footprints in Japan, North America, Europe, Asia, and South America.
