Marsh has reached an agreement with ENEOS Holdings, Inc. to take over two insurance operations within the conglomerate: ENEOS Insurance Service Co., Ltd. and the insurance arm of ENEOS Material Trading Co., Ltd. The deal is targeted for completion in the third quarter of 2026 (Q3 2026). Neither party has disclosed the financial terms. The transaction arrives at a time when Japan’s deal market is under notable pressure, with overall activity in the country declining sharply in the first quarter of 2026 (Q1 2026), according to GlobalData figures.
ENEOS Insurance Service has been in operation since 1957 and is based in Tokyo. The firm serves clients across Japan with a range of commercial insurance products, including liability coverages, service station-related policies – among them soil remediation and disaster compensation insurance – car lease insurance, and workers’ compensation insurance. Risk advisory services for group companies are also part of its offering, as are employee benefit programs tailored to the ENEOS Group. The insurance department of ENEOS Material Trading operates on a smaller scale, concentrating on personal insurance for businesses in the chemical industry and for ENEOS Material Trading’s own workforce.
For ENEOS Holdings, the divestiture is part of a portfolio restructuring exercise. Takashi Anada, general manager of ENEOS Holdings and president and representative director of ENEOS Insurance Service, said the group had determined that placing the two units under a dedicated insurance and risk management firm would serve their long-term development better than retaining them in-house. “As the ENEOS Group strengthens its management structure and restructures its portfolio, maximizing the strengths and growth potential of ENEOS Insurance Service and the insurance division of ENEOS Material Trading with an optimal partner will better support future growth for the business and its employees. Developing the business under Marsh Japan, a leader in insurance and risk management, best positions the company for long-term growth,” Anada said.
Marsh Japan was established in 1955 and has since built a seven-decade presence in the Japanese insurance brokerage and risk advisory market, serving companies across a range of industries and sizes. Chikara Nakanishi, president and representative director of Marsh Japan, indicated the firm intends to retain the client relationships the ENEOS units have built while layering in its own capabilities. “ENEOS Insurance Service and the insurance division of ENEOS Material Trading have built deep, longstanding trust with their clients – strengths we will preserve as we integrate their capabilities with Marsh’s global risk management expertise, advanced analytics, and market-leading innovations. Together, we will broaden product-related and extended warranty offerings and continue to provide comprehensive employee benefits, all supported by streamlined digital platforms and responsive advisory teams to help clients manage exposures and enhance resilience,” Nakanishi said.
The deal gives Marsh Japan access to specialized commercial lines that have historically been administered through affiliated or captive brokers within large industrial groups – a structure common among Japanese conglomerates. Coverage categories such as service station-specific policies and chemical-sector insurance represent segments that are not typically distributed through general brokerage channels.

The acquisition is taking shape against a backdrop of declining deal activity across the Asia-Pacific region. GlobalData’s analysis of its Financial Deals Database found that the combined volume of M&A, private equity, and venture financing transactions across APAC dropped by roughly 6% in Q1 2026 relative to the same quarter a year earlier. Japan’s contraction was more pronounced than the regional average. Deal volume in the country fell by approximately 45% year-on-year during the first quarter, placing it among the weakest-performing markets in the region. South Korea posted a 27% decline, while Australia and Singapore each recorded drops of around 18%. India was roughly flat.
Breaking down the figures by deal type, M&A activity across APAC contracted by 26% year-on-year, while private equity deal volume fell by 42%. Venture financing moved in the opposite direction, growing 21% over the same period – a sign that early-stage investment appetite held up even as larger transactions stalled. China stood apart from the rest of the region, with deal volume rising approximately 38% year-on-year in Q1 2026. That growth partially cushioned the regional decline but was not enough to offset the pullback elsewhere.
The Marsh-ENEOS transaction is among the more prominent insurance brokerage deals in Japan at a time when the broader M&A environment is subdued. It raises questions about whether other large Japanese industrial groups may similarly look to exit affiliated insurance operations as part of structural reorganizations. The answer to that question will likely depend in part on whether deal conditions in Japan improve from the levels recorded in early 2026.
