After Togo, Teioh and both Yamaguchis left the WWF, Michinoku and Funaki began wrestling as a tag team using the name Kaientai. They were primarily comedy jobbers, best known for their "Indeed!" skits in which voices in English were dubbed by Bruce Prichard into their promos while they badly lip-synced. Their first tag team match together came in the form of a loss to the Hardy Boyz. At WrestleMania 2000 the pair were part of a hardcore battle royal for the WWF Hardcore Championship, Funaki even became the Hardcore champion for a small amount of time however Michinoku never held the title. Taka's biggest venture in WWF came when he challenged Triple H for the WWF Championship on the April 10, 2000 edition of "Raw", coming up short despite interference on his behalf from Funaki and the Acolytes Protection Agency. In 2000 they had a chance to become the number one contenders for the WWF World Tag Team Championship in a number one contendership battle royal in which The APA won. In 2001 KaiEnTai took on the Dudley Boyz for the WWF Tag Team Championship but failed to capture them. In 2000 and 2001 Michinoku had multiple opportunities to become the WWF Light Heavyweight Champion taking on Dean Malenko, Jeff Hardy and others. In their last match together as KaiEnTai, due to Michinoku leaving the WWF, they defeated Justin Credible and Raven on the October 20, 2001 edition of "WWF Jakked".
