Example Input: Question: Which of Kuroda's contemporaries had more championships, Hosaka or Tanaka? Passage:Kuroda began his professional wrestling career in January 1993, when he was trained by Pro Wrestling Crusaders (PWC) at their dojo and made his debut on March 18, 1993 against Hideki Hosaka. PWC closed after a few months and Kuroda resumed his training at the Frontier Martial-Arts Wrestling (FMW) dojo. He made his FMW debut as a fan favorite with Masato Tanaka by losing to Dark Ranger and Masaru Toi in a tag team match on October 15. Kuroda remained in the low card for many years in the company and was usually utilized in opening matches on the card and served as a enhancement talent against higher level opponents, winning against only lesser known talent. He was often paired with fellow newcomer Tanaka in mid-card matches during the early years of his career and often wrestled Tanaka, Koji Nakagawa and Gosaku Goshogawara. Kuroda's first main event match took place on November 26, 1994, when he teamed with Atsushi Onita, Katsutoshi Niiyama and Masato Tanaka to defeat Mr. Pogo, The Gladiator, Hideki Hosaka and Hisakatsu Oya in a no ropes barbed wire street fight deathmatch. Kuroda would team with Onita, Niiyama and Tanaka in several street fights during late 1994 and early 1995. In the summer of 1995, Kuroda was entered into the Young Spirit Tournament, a round robin tournament consisting of rising rookies of the company. He would lose all of his matches in the tournament against W*ING Kanemura, Hideki Hosaka, Koji Nakagawa and Hido, while wrestling Masato Tanaka to a double knockout to gain one point in the tournament.
