On January 15, 1999, Yasuraoka lost the International Junior Heavyweight Championship to Masao Orihara, ending his reign at 588 days. On March 1, Yasuraoka and Tomohiro Ishii defeated Shinjiro Otani and Tatsuhito Takaiwa to win their second International Junior Heavyweight Tag Team Championship as a team, while marking Yasuraoka's fourth tag team championship reign. At 7th Anniversary Show, Yasuraoka teamed with Masaaki Mochizuki against Naohiro Hoshikawa and Super Delfin in a losing effort. Immediately after losing, Yasuraoka competed against Mochizuki in a match, which Yasuraoka lost. This would be Yasuraoka's last match as he announced his retirement from wrestling after the match, which led Yasuraoka and Ishii to vacate the International Junior Heavyweight Tag Team Championship.
