After three years of construction as one of North Texas’s largest economic developments, hundreds gathered for Toyota’s North American headquarters grand opening ceremony on Thursday evening.

The headquarters have been projected to produce roughly $7.2 billion in economic output over the next 10 years—accounting for the ripple effect it will have on the city economy, Plano’s Economic Development Director Sally Bane told Community Impact Newspaper for a previous article.

“We have more than 2,500 people on the ground in North Texas,” Toyota spokesperson Aaron Fowles said in an email.

The global automotive manufacturer expects to employ approximately 4,000 people at its new location once all staff members have relocated.

“Most relocating team members should be here by December,” Fowles said.

As part of the ceremony, Toyota, in partnership with United Way of Dallas and Toyota Financial Services, presented a $1 million grant to aid homeless women and children in Collin County.

The ceremony included remarks from Plano Mayor Harry LaRosiliere, Texas Gov. Greg Abbott and Toyota Motor North America’s CEO James Lentz.

Abbott said Japanese businesses that have relocated to Texas say they choose to do so for “the quality workforce that Texas has.”
