Born in Chiba, Chiba prefecture; Japan on November 5, 1985, Tanaka is the second oldest of 5 siblings, all brothers and raised by their single mother. His younger brother Juri is also an actor and signed with Johnny & Associates. Juri along with Tanaka's youngest brother Subaru even appeared alongside Tanaka in the first episode of the TV series Tokkyu Tanaka 3 Go in which Tanaka played the lead role. His younger brother Hyouga is also an actor, and Tanaka's older brother is named Kazunaru.

Before Tanaka was born, his mother thought he would be a girl, so she thought of the name Maria (Saint). But he turned out to be a boy instead, so the Kanji letter of his name '聖' was kept, but its pronunciation was changed to “Kōki” (“Kōki” also means “Saint” in Japanese). Furthermore, when he was little his face was so cute and feminine that he was often mistaken for a girl.

Tanaka joined Johnny & Associates in 1998. He once stated the reason why he applied was “My mother sent the application form behind my back. So I went to the audition without knowing anything at all. She told me it was because my cousin applied too. Therefore, we went to the audition together. But in the end, my cousin failed, while I passed.”

Tanaka graduated from Horikoshi High School, and eventually went to study at Josai International University, but he quit halfway. He loves animals so much that he originally wanted to become a veterinarian.
