The disappearance of Julius Ssekitoleko came at a time of high public concern over coronavirus risks as thousands of foreigners arrive for the Games.
“Today, the man was found in Mie Prefecture with no injuries and no involvement in any crime,” an Osaka police official, who declined to be named, told AFP.
“He carried his own ID and identified himself. It is not certain to whom we should send the man — the team or the embassy.”
The alarm was raised on Friday after Ssekitoleko failed to show up for a coronavirus test and was not in his hotel room.
The 20-year-old had recently found out he would not be able to compete at the Tokyo Games, which open on Friday, because of a quota system.
