Tatsuro Toyoda, the former Toyota Motor Corp president who led the company's climb to become one of the world's top automakers, has died. He was 88.

Toyoda, a son of the company's founder, died Dec 30 of pneumonia, the Japanese automaker said Saturday.

Toyoda, the automaker's seventh president, stepped down as president in 1995, while continuing in other posts, such as adviser, a title he held until his death.

He was instrumental in setting up the California joint venture with U.S. rival General Motors called NUMMI, or New United Motor Manufacturing Inc., which began production in 1984. At that time, it was heralded as a pioneer in international collaborations in the industry.

With a career focused on international operations, Toyoda served as NUMMI's first president, and is known for his efforts to bring together Toyota's corporate culture of super-efficiency, teamwork and empowering workers with American culture, including introducing a new style of labor-management relations.

Toyoda's father, Kiichiro Toyoda, founded the company. His brother Shoichiro Toyoda, whom he succeeded as president, is current President Akio Toyoda's father. When Tatsuro Toyoda handed the helm to an executive outside the Toyota family, there was speculation he may be the last Toyoda family member to lead the company.

But Akio defied skeptics to become president in 2009, underlining the family's legacy for the automaker. The rural house that marks the automaker's humble beginnings serves as a monument today. Toyota employees still repeat the sayings handed down by the family leaders about hard work and hands-on approaches.

The company name is spelled and pronounced with a "T," instead of the "D'' as in the family name, because it was considered to bring luck, according to fortune-telling.
