Tokyo 2020 Olympic organizers plan to start recruiting 80,000 volunteers for the games from September, but warned Wednesday that only those who can handle the workload will be taken on.

"We want to make sure that they take their jobs seriously, and also that they have the desire to do it because we are looking for those volunteers to continue to work for a minimum of 10 days," Tokyo 2020 Director-General Toshiro Muto told reporters after a meeting of the executive board.

"We are not looking for people who can only do this for one or two days. We are looking for people who are emotionally and mentally prepared to do this."
