Kazumi Totaka (戸高一生, Totaka Kazumi), born 1967 is a music composer for many major Nintendo games, including Mario Paint and Animal Crossing. He occasionally also does voice acting for Nintendo games, including Yoshi from the Mario and Yoshi series.
The infamous "Kazumi Totaka's Song" is a short, looping song, earliest cited feature in X, that has been heard in almost every game he has worked on. Such games include Mario Paint, Animal Crossing, Animal Crossing: Wild World, Link's Awakening, Yoshi Touch & Go, Super Mario Land 2, Virtual Boy Wario Land, Pikmin 2, Luigi's Mansion, and Yoshi's Story.
Other games which Kazumi Totaka has worked on, but have unconfirmed appearances of the song, include Wii Sports, Wario Land: Super Mario Land 3, and Wave Race 64.
Animal Crossing series
To hear the song in Animal Crossing or Animal Crossing: Wild World, enter the request "K.K. Song" from K.K. Slider between 8pm and midnight on Saturday nights. You will also receive an aircheck to listen to in your house (requesting is not required in Wild World). K.K. Slider has the real name of Totakeke, which is Totaka's name shortened in Japanese. Totakeke is said to be an animal version caricature of Totaka. This name could be derived from how Totaka's name is said in Japanese (the last name coming first), Totaka Kazumi.
