In 1994, Bischoff, by now the president of World Championship Wrestling (WCW), hired Onoo as an off-camera international consultant.

Onoo (referred to as Kazuo Ishikawa) also co-hosted the WCW presentation of Collision in Korea alongside Eric Bischoff and Mike Tenay.

He lost that title in a rematch with Malenko at WCW's Clash of the Champions XXXIV supercard, after botched interference by Onoo.

Dragon then won the WCW Television Championship from Prince Iaukea on a Nitro in April and defended the title against former champion Steven Regal at Slamboree.

[4] Onoo then managed Akira Hokuto who won the WCW Women's Championship over Madusa in the finals of the tournament to crown the first champion on December 29 at Starrcade in Nashville, Tennessee.

Onoo also turned his attention to managing many of WCW's luchadores, taking both Psychosis and La Parka under his wing to feud with Dragon.

Later, when luchador Konnan joined the nWo, Onoo sent both Psychosis and La Parka after him in subsequent matches on Nitro, with both ending in defeat.

In general, their team was a reminiscence of the Jackie Chan's and Chris Tucker's characters from the film Rush Hour.

After being released by WCW in November 1999 (Bischoff was by then no longer with the company), Onoo, Bobby Walker, Hardbody Harrison and several African American wrestlers launched a racial discrimination lawsuit against AOL Time Warner.
