Japanese corporate executives and general counsels (GCs) are increasingly encountering the stark contrasts between Japan’s legal system and that of the United States. In Japan, litigation is rare and less confrontational. The adversarial posture and invasiveness of U.S. litigation is often disorienting.

Japanese companies entering or operating in the United States and Europe face unique legal and regulatory hurdles. The U.S. system imposes rigorous compliance obligations, from export controls and sanctions to foreign investment reviews under the Committee on Foreign Investment in the United States (CFIUS). Litigation risks are significant, with extensive discovery requirements and exposure to large-scale commercial disputes. Companies also must navigate evolving data privacy and cybersecurity laws, environmental, social, and governance (ESG) and supply chain regulations, and industry-specific enforcement in sectors such as automotive, shipping, semiconductors, and financial services.
Japanese businesses expanding into the United States often focus on customers, site selection, and supply chains. But the greater shock usually comes from U.S. workplace law. Labor and employment law in the States is decentralized, aggressively enforced, and often counterintuitive to Japanese executives accustomed to centralized and consensus-driven practices. And missteps can quickly escalate into costly litigation or reputational harm.
Recent U.S. court decisions are reshaping the legal landscape for Japanese companies operating in America, from massive antitrust verdicts to contested tariff refunds and discovery conflicts. Five critical developments from May through July 2026 demand attention from Japanese businesses engaged in U.S. trade and litigation. Understanding these rulings is essential for managing legal risk and protecting commercial interests in the American market.
To bridge this gap, U.S. law firms are increasingly tailoring their services to meet the specific needs of Japanese clients. Firms like Steptoe and Jenner & Block have established dedicated Japan practices, staffed by attorneys fluent in Japanese and well-versed in both legal systems. These practices aim to guide Japanese companies through the complexities of U.S. law, offering counsel on compliance, litigation, and regulatory matters.
As Japanese corporations continue to expand globally, understanding and adapting to the legal environments of their host countries becomes imperative. The proactive engagement of specialized legal counsel can mitigate risks and facilitate smoother operations in foreign markets.
