藤田ミノル
In April 2000, Makabe entered the Super J-Cup, a 16-man single-elimination tournament held in Michinoku Pro, involving junior heavyweights from a number of different promotions; he was eliminated in the first round by Gran Hamada. Later that month, Makabe also participated in NJPW's Young Lion Cup, a six-man round-robin tournament exclusive to young wrestlers; he finished in first place for the group stage, defeating all of his opponents (Kenzo Suzuki, Hiroshi Tanahashi, Wataru Inoue, Katsuyori Shibata and Masakazu Fukuda by forfeit), though he lost to second-place finisher Kenzo Suzuki in the final. Shinya continued his tournament participation in May and June, entering New Japan's Best of the Super Juniors (BOSJ) round-robin tournament to decide the company's top junior heavyweight wrestler. Makabe finished in last place out of six in Block A, scoring two points by defeating Dr. Wagner, Jr. He later defeated Minoru Fujita, who finished in last place for Block B to determine the tournament's 11th-place finisher, leaving Fujita at #12. Makabe received the first title shot of his career on September 12, 2000, teaming with Jyushin Thunder Liger to unsuccessfully challenge Koji Kanemoto and Minoru Tanaka for the IWGP Junior Heavyweight Tag Team Championship.
