Summary · why it matters

Mizuho Securities President Yoshiro Hamamoto has laid out a strategy centered on "connecting" companies and investors, doing what major U.S. and Japanese firms cannot. In SpaceX's June 2026 listing, which raised 85.7 billion dollars, or about 14 trillion yen, in the largest IPO ever, Mizuho Securities' U.S. unit was the only Japanese brokerage to join the lead underwriter group, selling about 80 percent of the roughly 350 billion yen raised in Japan, with Rakuten Securities and SBI Securities selling the rest. The effort added about 1,000 new wealthy clients' accounts, and mass-retail customer accounts also grew. Hamamoto said that unless the firm makes substantive proposals to customers whose attention was drawn to Mizuho Securities by handling SpaceX shares, it will be a waste of a treasure, and that this IPO is only the entry point, expressing his eagerness to expand the number of accounts further. Through its alliance with Rakuten Securities, Mizuho Securities handles contact with the mass market, and as of fiscal 2026 their combined assets under custody stand at 121.7 trillion yen, with Mizuho Securities at 63.0 trillion yen and Rakuten Securities at 58.7 trillion yen, surpassing Daiwa Securities' 116 trillion yen, and by fiscal 2030 the two are projected to reach 212.2 trillion yen combined, chasing Nomura.
