Nomura Holdings Inc. is embarking on a fresh drive to convince individuals to pay fees for managing their money rather than commissions based on trading — a move that may prove challenging as it seeks to revive its retail business.

The nation’s biggest brokerage recently created a Chief Investment Office to bolster advice for individual clients as it prepares to introduce new discretionary portfolio management services in the retail division. Such services typically charge a fixed fee.

"We will be working to further improve performance” for investors, said Chie Toriumi, a senior managing director who oversees the office of 10 people, in an interview.
