Ko Takeuchi is a video game artist and design director at Nintendo, mostly known for designing the characters of the WarioWare and Rhythm Heaven series, as well as for establishing the characteristic cartoony style of both series.
After graduating from the Horikoshi High School in Tokyo, Takeuchi studied at the Cartooning Faculty of the School of Visual Arts in New York. Back in Japan, after a small time in the company Warp where he worked on the game D-2, he joined Nintendo at the R&D1 department.
In WarioWare, Inc.: Mega Microgame$!, Takeuchi was put in charge of redesigning Wario and creating all of the original cast characters of the title. He kept working on further titles of the franchise as art director and designing many other characters. Takeuchi also reprised those roles in the Rhythm Heaven series, starting with Rhythm Tengoku. He has been the main responsible of establishing the trademark art style of both series.
Outside of Nintendo, Takeuchi also runs since 2001 Kokosac Inc., his personal design studio, along with his wife. He is particularly popular in social media websites for posting various caricatures of video game, anime and cartoon characters, as well as celebrities and memes.
