What was the name of Nintendo’s first home video game console released in Japan?

Color TV-Game 6 was Nintendo’s first home video game console, released in Japan in 1977.

Nintendo developed the Color TV-Game 6 with Mitsubishi Electric. The dedicated console contained six variations of a simple tennis-style game and connected directly to a television. Unlike cartridge-based systems, it did not accept interchangeable software; its built-in games were part of the hardware.

The system appeared during Nintendo’s early transition into electronic entertainment. Before this period, the company was best known for playing cards, toys, and arcade-related products. The Color TV-Game line gave Nintendo experience in designing and marketing home electronic games before the company created more advanced platforms.

The Family Computer, or Famicom, was a later and much more capable cartridge console released in 1983. That makes it a common incorrect answer to this question. Nintendo also produced Color TV-Game 15, but Color TV-Game 6 came first.
