In the 80s, Japan was honestly more hated in some circles than Russia was. It wasn't workmanship so much as the fact that their automotive and electronics industries were eating the US alive in the 1980s, and the fact that Japanese companies were buying up a lot of American companies and real estate. In 1995, due to a stock market spike, the Japanese economy was briefly worth more on paper than the entire US economy was. The market correction that followed pretty much put an end to the "Japan is taking over the world" meme. If you've ever seen movies from the 80s set in the future, notably Back to the Future II, you'll notice they all have America's economy pretty much owned by Japan in its entirety.
And Nintendo got a lot of this hate because it was the most familiar face of Japan in American homes. The American video game industry was on life support at that time. Atari and Activision were going bankrupt, and even EA wasn't doing all that well.
