Cook Pine Capital

Cook Pine Capital was established in 2005 by Eiichiro Kuwana and Yumi Mera Kuwana. The founders drew on prior roles at Goldman Sachs and Morgan Stanley to create an independent platform that serves a small number of ultra-high-net-worth families. The firm allocates across public equities, private equity, hedge funds, and philanthropic vehicles. It commits through fund-of-funds structures and selective direct opportunities while maintaining exposure in North America, Europe, and Asia. Investment stages include buyouts and growth equity. No specific portfolio holdings are disclosed in public materials. The team comprises eight named professionals. Additional offices are not reported. Eiichiro Kuwana serves as Treasurer of the U.S.-Japan Council board and holds a seat on Brown University’s President’s Leadership Council. No operational events from the last twenty-four months appear in available records. Cook Pine Capital is registered as an investment adviser with the U.S. Securities and Exchange Commission and the Ministry of Finance Japan. This dual regulatory posture requires ongoing compliance reporting that shapes its operational and client documentation processes.
