The North American Toyota-Denso Cup - World Go Oza was a relatively new world go championship. Held as a biennial event in even-numbered years starting in 2002, the tournament ran as 32-player knockout event that culminated in a best-of-three final match. Since the second running of the event, the sponsors invited North America to send two representatives to the world championship tournament.
As of June 16, 2009, the Nihon Ki-in has confirmed that the Toyota & Denso Cup World Go Oza has been canceled by the sponsors.
