Mr. Uchida was the board’s unanimous choice, officials said.

Nissan is part of a global carmaking alliance with the French company Renault and Japan’s Mitsubishi Motors, but Nissan and Renault have repeatedly clashed over management issues. The relationship rapidly deteriorated after the exit of Mr. Ghosn, who had worked to merge the companies, an effort that rankled some at Nissan who felt the company should remain independent.

Mr. Uchida was selected because of his experience abroad, as well as his understanding of the importance of the alliance with Renault and Mitsubishi, the head of the board’s nomination committee, Masakazu Toyoda, told reporters.

The company also announced the appointment of two other senior executives, in an effort to show it was making a clean break from the management issues that have plagued it since Mr. Ghosn was detained last November.

Ashwani Gupta, the chief operating officer at Mitsubishi and a former executive at Renault, was named Nissan’s chief operating officer. Jun Seki, a senior vice president at Nissan, will become vice chief operating officer.

“We selected the people who can show that this is a new Nissan in a strong way,” Mr. Kimura said.

Renault had no immediate comment on the announcement. But Jean-Dominique Senard, Renault’s chairman and a member of Nissan’s board, saw the appointments as a positive move that could help the alliance get past its recent problems, according to a person familiar with his thinking. Both Mr. Uchida and Mr. Gupta have worked closely with the French automaker in the past and understand that preserving the alliance is critical to Nissan’s future as it faces a rapidly changing and increasingly competitive auto-industry, the person said.
