I don't know about the majority, but Honda opened up the Marysville plant back in 1982. So they've been making/selling American made Honda's since the 1983 Model Year, I think. Isn't the 1993 HondaAccord the year of the 10th anniversary edition?
All of our Honda's up until my 2003 Accord and my mom's 2006 Civic have been made in Japan. (Well, I don't know about the motorcycles, but I'm not including those)
Made in Japan: 1st gen Civic 1st, 2nd, 4th, and 6th gen Accord. 1st gen Odyssey
