Cobalt Investments Co., Ltd.

The firm serves as the unlimited liability partner (general partner) for funds in the MCP series, such as MCP V (also referenced as MCP5), which target mid-sized and small Japanese enterprises facing business succession or other operational challenges. These funds typically pursue majority stake acquisitions and deliver hands-on post-investment support, including successor recruitment and development, management enhancements, sales channel expansion, and overall enterprise value growth.

Established in 2017 and registered with Japan's Financial Services Agency for special business activities involving qualified institutional investors, the company participates in fund structures backed by entities such as the Japan Small and Medium Enterprise Corporation (with contributions around 6 billion yen in one documented case), Mizuho Bank, regional financial institutions, and other investors. Individual funds often reach total sizes of approximately 30 billion yen.

Operating exclusively within Japan, Cobalt Investments Co., Ltd. focuses on domestic SME private equity opportunities. In the specialty chemicals sector, it has been linked through its funds to the acquisition of shares in GOO Chemical Co., Ltd., a Kyoto-based manufacturer of electronic materials, textile chemicals, and resins, with the intent to establish it as a subsidiary.

The company maintains a niche position in Japan's private equity landscape, emphasizing active ownership in succession-related transactions rather than broad industry diversification or international operations.
