History
A part of Super Mario 3D Land's development was outsourced to 1-UP Studio as to have the game released in the 2011 Holiday season. Director Koichi Hayashida supervised the team to make sure that they would understand Nintendo's game design philosophy and work in harmony with the main development team. 1-UP Studio was also the developer for Super Mario 3D World, Captain Toad: Treasure Tracker, and Super Mario Odyssey.
