Former Citadel portfolio manager Takeo Serizawa will join a new Japan-focused hedge fund, teaming up with one-time Point72 Asset Management¡¯s Japan head, Tomohiro Yamaguchi, to tap investor interest in the country.

Serizawa will become chief investment officer of Hong Kong-based Invictus Investment Partners, after his one-year non-compete agreement with Citadel ended last week, the two men said during an interview. That will allow Yamaguchi to focus on risk management and business operations as chief executive officer.

Invictus is among a string of Japan-focused hedge fund startups that have sprung up. The country¡¯s corporate governance improvements and economy have rekindled investor enthusiasm. International investors are looking for funds that have the right business setup and investment approach to accommodate hundreds of millions of dollars of capital.
