Life and Work
Ko Takeuchi was born in 1970 in Kōchi in the Kōchi Prefecture of Japan. He graduated from the Horikoshi High School in Tokyo, then Takeuchi studied at the Cartooning Faculty of the School of Visual Arts in New York City, United States. After his return to Japan, he applied to different companies related to visual arts, including at least one game company, the now-defunct developer Warp. He joined said company and entered the video game industry this way. During his time at Warp, Takeuchi worked on Sega Dreamcast games. Afterwards, he joined Nintendo in 2000. The first Nintendo game he was involved with is Tottoko Hamtaro: Tomodachi Daisaku Ikusa Dechu, released in the same year. Takeuchi took the role of the assistant director. The next game he worked on is Wario Land 4, for which he was responsible for the background graphics. In the year of the game's release, 2001, Ko Takeuchi and his wife Sachiko Imai founded their own design studio Kokosac located in Kyoto.

Takeuchi is responsible for the character design in all games of the WarioWare series, starting with WarioWare, Inc.: Minigame Mania released in 2003, and is a key designer of the franchise in general. He designed newly introduced characters such as Jimmy T., Mona, 9-Volt and Ashley who have become a recurring cast since. The title character Wario has also been given a new appearance by Takeuchi for the series, wearing a biker outfit. During the development of WarioWare, Inc.: Minigame Mania, Ko Takeuchi also sometimes worked with Hiroji Kiyotake, the original designer of Wario.

His characters, be it in video games or other media, are usually based on real people, including his friends, colleagues and people he met on the street. When Ko Takeuchi sees a fascinating person who might be the inspiration for a new character, he draws them in his small sketchbook. Takeuchi's style, which is commonly seen as "cute", is influenced by artists such as Akira Toriyama and Yoichi Otabe.
