You should mention that you mean the japan console market, not US.

In 1983 the US console market collapsed because of the many low-quality atari games and not-licenced consoles. https://en.wikipedia.org/wiki/Video_game_crash_of_1983

The NES was released in US test markets as the redesigned NES in October 1985.
