Frequently asked questions

Is Mizuho Securities Principal Investment a traditional private equity fund or a captive investment arm?

It operates as a captive direct investment division of Mizuho Securities, deploying proprietary balance-sheet capital rather than managing third-party committed funds. This makes it structurally closer to a corporate principal investing desk than to a blind-pool general partner. Unlike independent Japanese GPs that must return capital to external limited partners, the unit's investment horizon and exit discipline are governed by Mizuho's internal capital allocation framework and regulatory capital requirements.
