Training began Thursday for leaders selected to manage volunteers who will assist at competition venues and the athletes village for this summer's Tokyo Olympics and Paralympics, even as public skepticism remains high over whether the games should be held amid the coronavirus pandemic.

The training involves around 6,000 of the roughly 80,000 volunteers who have signed up for the games, with Thursday's session the first of around 20 to be held through May.

Around 310 people participated online in either the morning or afternoon session and were briefed on their role as a volunteer team leader, which includes holding meetings prior to shifts, checking on volunteers and confirming the roster for the next day.
