ヒロ斎藤
In the 1990s, Hase had many memorable encounters with famous Japanese talents first in New Japan, and later All Japan. In June 1990, Hase had a near-death experience in the ring, after being knocked out by a backdrop from Tatsutoshi Goto. Hase would form a successful tag team with Kensuke Sasaki in March 1990, winning the IWGP Tag Team Championship twice. On November 1, 1990, Hase and Sasaki defeated Masahiro Chono and Keiji Mutoh to win the title and held on to the titles until December 26, 1990, losing them to Super Strong Machine and Hiro Saito. Their second reign came by regaining them from Machine and Saito on March 6, 1991, but lost the titles on March 21, 1991, to The Steiner Brothers. Hase was involved in a classic December 14, 1992 encounter with The Great Muta, in which the "Muta Scale" was created, due to the incredible amount of blood shed by Muta, which was payback for Muta bloodying Hase on September 14, 1990.
