Honda Motor Co celebrated a huge milestone this week, after building its 20 millionth vehicle in the United States, along with its 10 millionth Accord, according to a company press release.

Honda was the first Japanese automaker to open an auto assembly plant in the United States.

The company's Marysville, Ohio manufacturing plan produced its first car, a Honda Accord sedan, back on Nov. 1, 1982.

"We are deeply aware that our ability to reach this milestone results from the trust that 20 million customers have placed in our products, and we appreciate their support over the past three decades," said Hidenobu Iwata, president and CEO of Honda of America Mfg. and head of Honda's North American manufacturing, according to the release. "We also value the commitment made by tens of thousands of associates at Honda and our hundreds of suppliers in the U.S. who build products of the highest quality for our customers."

The Japanese-automaker produced 1.3 million vehicles in the United States in 2013. This represents an increase of 7.4 percent compared to 2012 and a record for the company in general, according to Reuters.

Honda manufactures vehicles at assembly plants in nearby East Liberty, Ohio, Lincoln, Alabama, and Greensburg, Indiana, and at the Ohio plant.

Those plants produce over 11 different vehicles, including four passenger cars and seven light trucks.

A fifth plant is currently under construction in Marysville, Ohio.

Sales for new Honda cars, SUVs, and crossovers rose approximately 7.2 percent last year to 1.53 million in the U.S., according to a recent sales report issued by the automaker.
