Heisei Ishingun
After 14 years with the New Japan, Ohara's contract was not renewed in 2004, and he would venture on freelancing with Kensuke Office, Dradition and Big Mouth Loud. He reunited with Goto as The Mad Dogs for Big Mouth Loud in 2005, before making brief returns to New Japan, as Makai #3 and himself. His last appearance for New Japan occurred on March 6, 2007, teaming with Shiro Koshinaka as Heisei Ishingun for one night, in a losing effort against Riki Choshu and Super Strong Machine. In 2007, he joined Antonio Inoki's new promotion, Inoki Genome Federation. In 2008, he retired due to injuries suffered in a car accident.
