TOKYO (Reuters) - Tokyo 2020 still faces questions on judo, sailing and triathlon, where issues about water quality in particular remain unresolved, International Olympic Committee (IOC) Vice President John Coates said on Tuesday with just over two years to prepare.

Coates, who is also chairman of the IOC's Coordination Committee for the 2020 Tokyo Games, on Monday said Tokyo must answer tough questions from national Olympic committees or risk losing confidence in their ability to host the games.
