From the Olympics to Tokyo's annual video game convention, Japan has a strong track record of hosting major international events. But this year's Asian Games in Nagoya and the wider Aichi Prefecture were marred by problems.

There were diplomatic blunders, transport errors and accommodation chaos. In comment fields online, some branded it the "worst Games in history" and urged a "full investigation".

Prof Kozo Tomiyama, who studies major sporting events at Osaka University, believes organisers were unable to handle the unexpected.

"If these problems damage international confidence in Japan's ability to operate sporting events, they could also affect Japan's ability to attract international competitions in the future," he warned.

The deputy director general of the Games, Takaaki Omi, admitted organisers had faced a range of unforeseen issues, but insisted they took on feedback and made improvements.
