Animal Hamaguchi
Upon SWS's folding, Kitahara joined Tenryu in forming WAR. Now known as Koki Kitahara, in the early years of WAR, Kitahara would be Tenryu's main tag team partner in battles against New Japan Pro-Wrestling, but in later years, he teamed with Koji Kitao. In September 1994, Kitahara toured Mexico for Consejo Mundial de Lucha Libre. In April 1995, Kitahara won his first championship in Japan, the WAR World Six-Man Tag Team Championship, with Tenryu and Animal Hamaguchi. He won two more, with Arashi, Nobutaka Araya, and Lance Storm as his partners. In 1999, WAR folded.
