Wrong national anthems were played three times at the Asian Para Games in Japan's Nagoya this week, just days after the city hosted the mishap-plagued Asian Games.
Nagoya Mayor Ichiro Hirosawa apologized on Wednesday for the latest error, which occurred despite officials' pledges to implement steps to prevent mistakes, including playing the correct national anthems.
"These things happened during the Asian Games, so of course the operations were reviewed and examined based on the lessons learned. The fact that it happened again is really just unacceptable," the mayor told a press conference.
The Asian Para Games is taking place in the central Japanese hub city through Saturday, featuring around 4,000 athletes and officials in 18 sports.
On Monday, the Iranian anthem was wrongly played during a men's para taekwondo and a women's para taekwondo ceremonies, according to the city.
In the former case, the anthem played in its entirety, while in the latter, it was stopped after the Mongolian competitor who was receiving the gold medal pointed out the error.
On the same day, the Iranian anthem was played again during a women's para taekwondo ceremony, where a Mongolian competitor was receiving the gold medal, according to the city.
The incorrect music was stopped after the Mongolian delegation pointed out the error.
Organizers then played the Mongolian anthem after the music was provided by the delegation, Nagoya officials said.
Separately on Monday, officials broadcast the South Korean anthem for about five seconds, instead of the Chinese one, before a sitting volleyball match between China and Iran.
"It is unacceptable, or rather, it's painful. I am very sorry about it," the mayor said, adding that he felt the tournament was otherwise progressing smoothly.
The Asian Games, which concluded in early October, faced heavy criticism for shortcomings ranging from inadequate accommodations for athletes to the playing of wrong national anthems.
On Sept. 18, organizers played North Korea's national anthem for the South Korean hockey team.
