Summary
Millennium Management has recruited Tomiyuki Oji as a senior portfolio manager based in Tokyo, according to Bloomberg reporting. Oji, a former managing director at Nomura Holdings, most recently served as Asia-Pacific head of index flow derivatives trading within Nomura's brokerage business. His appointment reflects Millennium's deliberate effort to scale its equities operation in Japan, one of the world's largest institutional markets.
Oji's career trajectory demonstrates substantial expertise in Japanese equities markets. He spent 15 years at Goldman Sachs' Japanese securities business developing capabilities in equity derivatives trading before transitioning to Nomura, where he held leadership responsibility for the region's index derivatives flow business. This background positions him to manage complex multi-asset equity strategies within Millennium's diversified portfolio management framework.
The hire follows another significant Tokyo-based equities appointment. Masaya Imabuchi, previously a manager at Mizuho Securities, joined Millennium as a senior portfolio manager in July 2026. The sequential hiring of two senior-level equities professionals from Japan's premier investment banks within a compressed timeframe signals intentional capital allocation toward expanding Millennium's Japan desk headcount and strategy capacity.
Millennium Management, a multi-strategy hedge fund operator, has historically maintained a significant equities business across global markets. The Japan expansion reflects broader institutional demand for sophisticated, locally-grounded portfolio management in Japanese equities, particularly given the specialized knowledge required for index derivatives trading and cross-asset hedging strategies. A Millennium representative declined to comment on the appointment.
