YOKOHAMA, Japan — Nissan’s embattled chief executive, Hiroto Saikawa, was re-elected to the company’s board on Tuesday, during an annual meeting in which shareholders vented their anger at the scandal-wracked company’s French partner, Renault.

Mr. Saikawa apologized on Tuesday to shareholders gathered at a hotel in Yokohama, where Nissan is based, for the company’s financial misconduct issues, which have rocked Nissan and led to charges against its former chairman, Carlos Ghosn. After his apology, Mr. Saikawa and other Nissan officials bowed to the assembled shareholders.

He said he would swiftly implement an overhaul of Nissan’s corporate governance structure, which shareholders approved on Tuesday. The new system — aimed at preventing a recurrence of the management problems that occurred under Mr. Ghosn’s tenure — introduces independent committees for nominations and compensation, putting the company in line with global governance standards.

“There’s a responsibility for the past, and there’s another responsibility, responsibility for the future,” Mr. Saikawa said.
