Minakuchi Engineering was a Japanese video game developer, who worked on various entries in the Mega Man series during the early-mid 1990s. They handled most of the Mega Man games on the Game Boy (apart from Mega Man II, which was developed by Biox), the compilation title Mega Man: The Wily Wars, and large portions of Mega Man X3. In all, they worked on six Mega Man titles, making them the third-most prolific Mega Man developer after Capcom and Inti Creates. Their other work with Capcom included the Game Boy version of Bionic Commando, as well as the SNES port of Magic Sword.
