After graduating from high school, he failed to take the police recruitment exam and lived a freeter life while attending a civil servant prep school. One day, he heard on TV that Mitsuharu Misawa, the founder of Pro Wrestling Noah said, "Anyone can be a professional wrestler if he has the guts."  One day while reading the back of the "Weekly Wrestling" magazine, he saw an article about Kenta Koabayashi (later KENTA). The article would mention that Kobayashi had passed the AJPW rookie test, without having any background in martial arts, something Shiozaki was lacking as well. Go would later mention that this article would inspire him, and this was when he began thinking of becoming a professional wrestler.
