IWGPタッグ王座
August 1997 skyrocketed Sasaki's rise to superstardom. On August 3, he won the G1 Climax tournament by defeating Hiroyoshi Tenzan in the final. A week later, he captured the IWGP Tag Team Championship with Kazuo Yamazaki. Finally at the end of the month, he captured the IWGP Heavyweight Championship by defeating long reigning champion Shinya Hashimoto, winning three major honors in a one-month span. Sasaki solidified his dominance in the heavyweight division by defeating both Masahiro Chono and Keiji Mutoh in his first two title defenses, thus defeating The Three Musketeers in three straight title matches. In April 1998, he lost the title to Tatsumi Fujinami. In March 1999, he won another IWGP Tag Team Championship with Shiro Koshinaka.
