History

The firm developed amid regulatory changes involving entities like the Financial Services Agency (Japan), the Tokyo Stock Exchange reforms, and corporate governance initiatives inspired by cases involving corporations such as Olympus Corporation and Toshiba Corporation. Expansion paralleled international trends exemplified by transactions in the 1990s and 2000s involving companies such as Sony Corporation and Hitachi, and was influenced by audit and advisory demand linked to cross-border deals with firms like General Electric and Siemens. In the 2010s and 2020s, Deloitte Tohmatsu deepened capabilities in digital transformation associated with vendors and partners such as Microsoft Corporation, Amazon Web Services, and SAP SE while responding to regulatory scrutiny reminiscent of matters faced by PwC and KPMG in global audit landscapes.
