Konno joined Nintendo in 1986, where he worked on positions such as assistant director in the beginning of his career, along with being the director for games such as Super Mario Kart and Super Mario World 2: Yoshi's Island.[1][2]
In 2015, Konno began managing Nintendo's mobile projects on his own production group at Nintendo Entertainment Planning & Development, the division resulting from the merger of Nintendo's main development and production divisions.[3]
