Life and work[edit]

Ko Takeuchi was born on November 28, 1970 in Kōchi in the Kōchi Prefecture of Japan.[2] Early in his life, he became interested in video games, such as the Game & Watch handhelds and the Famicom console. Takeuchi graduated from the Horikoshi High School in Tokyo, later he traveled to the United States of America and studied at the Cartooning Faculty of the School of Visual Arts in New York City.[3]

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.[4] During his time at Warp, Takeuchi worked on Dreamcast games, including D2, of which he was one of the designers.[3] 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 assistant director. The next game he worked on is Wario Land 4, for which he was responsible for the background graphics.[4] In the year of the game's release, 2001, Ko Takeuchi and his wife Sachiko Imai founded a design studio, Kokosac, located in Kyoto, Japan.[3]

Takeuchi is responsible for the character design in all games of the WarioWare series, starting with WarioWare, Inc.: Mega Microgame$! released in 2003, and is a key designer of the franchise in general. He designed characters for the WarioWare series such as Jimmy T, Mona, 9-Volt, and Ashley.[5] The title character Wario was also given a new appearance by Takeuchi for the series, wearing a biker outfit. During the development of WarioWare, Inc.: Mega Microgame$!, Ko Takeuchi also sometimes worked with Hiroji Kiyotake, the original designer of Wario.[4] He created the artwork for the Ashley no Halloween Night and Barbara & Ashley online comics. Additionally, he voices Joe in the Japanese version of the WarioWare series starting with WarioWare Gold.

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.[3] When Ko Takeuchi sees a fascinating person who might be the inspiration for a new character, he draws them in his small sketchbook.[4] Takeuchi's style, which is commonly seen as "cute", is influenced by artists such as Akira Toriyama and Yoichi Kotabe.[3]

During his studies, Ko Takeuchi had to put aside his passion for playing video games because he was so busy. Today, he still plays video games as time permits. Takeuchi has specifically mentioned his enthusiasm for the Mother series, referring to the game Mother as a masterpiece and stating that he played through Mother 2 (EarthBound) three times.[4][3]
