Ninja Hattori-kun — stories left

All 9 of Hudson's earlier Family Computer titles were ports from other platforms, or arranged ports, so this was the company's 10th original Family Computer title.

The game shipped 1,400,000 copies and became a hit. Its sales record for a game based on a manga stood for more than 12 years, until the Game Boy title Yu-Gi-Oh! Duel Monsters (1998).

In the "Game Report Card" reader poll run by the magazine Family Computer Magazine,it scored 18.92 out of 30, as listed separately.

Shinken Shobu" (2003) and Bobobo-bo Bo-bobo: 9kyoku Senshi Gyagu Yugo (2004) contain "Ninja Ochoboguchi-kun", a minigame made by replacing the characters of the bonus stage described above.

Speaking on the programme X Nen Go no Kankeisha-tachi, broadcast on 2021-10-12, Takahashi Meijin said that Hudson often ran events with the magazine CoroCoro Comic, and that this connection led to the company making a game based on the work of Fujiko Fujio, who also had close ties with CoroCoro Comic.

The game was originally scheduled for release in 1985-12, but it is said that it did not turn out to be much fun, so it was remade and the release was put back to 1986-3.

He states that the company then set out to make games of Doraemon and Ninja Hattori-kun, but because the world of Doraemon was hard to turn into a game, the Ninja Hattori-kun game was developed first (Doraemon was released at the end of 1986).

The dumbbells in this bonus stage were set up at the very end of the game's development by Shinichi Nakamoto, who was said to be the programmer. He said, "During development there was not even the idea of dumbbells, and development was in fact once completed in that state, with only chikuwa scattered about; at that point a mistake in memory management had left capacity to spare, so I put them in on a whim", and that was given as how they came about.
