Sompo Holdings, Inc. is a major Japanese insurance and financial services holding company headquartered in Tokyo. Its diverse global operations encompass domestic P&C (Property and Casualty) insurance, overseas insurance and reinsurance, domestic life insurance, and an expanding portfolio in nursing care, healthcare, and digital technologies. With a history tracing back to 1888, Sompo aims to provide solutions that contribute to the security, health, and wellbeing of its customers and society, striving to be a 'Theme Park for Security, Health & Wellbeing.'
The headquarters serves as the global command center for Sompo Holdings, overseeing strategic planning, corporate governance, financial management, and group-wide operations for its diverse subsidiaries worldwide.
The Sompo Japan Head Office Building, part of the complex where Sompo Holdings is located, is a landmark skyscraper in Nishi-Shinjuku. It was historically known for housing the Seiji Togo Memorial Sompo Japan Nipponkoa Museum of Art, famous for Van Gogh's 'Sunflowers'. A new, dedicated SOMPO Museum of Art building now stands adjacent, continuing this cultural legacy. The main office tower itself is a significant example of 1970s modernist architecture.

The Tokyo headquarters is pivotal for directing Sompo's extensive global network, formulating group strategy, managing risk, and fostering innovation across all business segments. Its location in one of Asia's primary financial centers underscores its importance in the global insurance and financial landscape.
