Kouichi Niwa, an equity analyst at Mizuho Securities Co., will leave the brokerage on Sept. 16, said Toshimitsu Okano, a Tokyo-based company spokesman.
Niwa covers consumer finance and insurance firms at Tokyo- based Mizuho Securities, a unit of Japan’s third-biggest bank by market value. He was ranked fifth by the Nikkei Veritas newspaper this year.
Mizuho will continue to analyze the companies covered by Niwa, Okano said.
