The three-day meeting was originally scheduled to take place at FIBA's headquarters in Mies, Switzerland on 18-20 June.
The International Basketball Federation decided to stage the event in Japan, where it will choose the host of the 2019 FIBA Basketball World Cup.
This change of location will maximise the impact of the decision and allow for large delegations and media in the region to attend the historical occasion.
Meanwhile, the Executive Committee meeting due to be held in Mies on 16-17 June will instead run on 18-19 June.
