With less than 15 months until next year's Tokyo Games, international sports federations voiced concerns Tuesday about event logistics including athlete services and venue presentation.

During an international sports meeting in the Gold Coast, Australia, officials from the Japanese organizing committee for the 2020 Olympics pledged to do their utmost to address the anxieties.

"We're extremely concerned with the service levels that are being proposed for athletes at venues," World Sailing chief executive Andy Hunt told the general assembly at the Association of Summer Olympic International Federations.
