Mercer, Mizuho Will Partner on OCIO Offerings in Japan

Under the bank’s Asset Management One subsidiary, the duo will offer outsourced CIO services to institutional clients.



Japanese bank Mizuho Trust & Banking Co. Ltd. and its asset management subsidiary, Asset Management One Co. Ltd., will partner with investment consultant and outsourced CIO provider Mercer to offer outsourced CIO services in the Japanese market.
 

Under the partnership announced Monday, Mercer and Mizuho will offer OCIO services to institutional investors, including pension funds, educational institutions and other clients of Mercer Japan Ltd. through Asset Management One. 

According to a Mizuho statement, the partnership aims to contribute to Japan’s Policy Plan for Promoting Japan as a Leading Asset Management Center, a set of policy guidelines which aim to reform the countries asset management sector and asset owners. The plan aims to promote the entry of new financial firms into Japan’s asset management sector by removing entry barriers and deregulation. 

“With a number of changes underway in Japan, the publication of the Asset Owner Principles provides an opportunity to rethink our approach to the asset management business,” said Yasushi Kusaka, Mercer Japan’s president and CEO, in a translated statement. “We believe that by combining our market-leading research and open architecture approach with a strong partner, we can strengthen our value proposition for clients and create greater opportunities for success.” 

Mercer manages $613 billion in assets globally, as of March 31, 2025.
