The Aichi-Nagoya Asian Games get under way this weekend under the shadow of a housing crisis that has organisers scrambling to placate athletes and officials from participating nations.

The tournament has been mired in complaints over housing options for athletes travelling to Japan, after the host nation decided not to build a dedicated Games village for the 17,000 competitors and officials.

To cut costs this year, organisers are relying on a cruise ship, temporary wooden cabins and hotels, but this temporary accommodation has met with criticism in the days leading up to the continental competition.

On Monday, South Korean officials slammed beds in shipping container-style huts as the “worst-ever”, as the South Korean basketball chief said the beds were too short to stretch out in.

Here’s everything we know:

Why are the Asian Games facing an accommodation crisis?

The official housing committee said the issue arose because they expected 15,000 athletes and officials, but numbers increased as new sports were added.

This year’s Games will feature several newcomers, including mixed martial arts, padel and surfing, as well as virtual taekwondo and teqball, which ‌‌combines aspects of football and table tennis.

Ahead of the Games’ opening, chief organiser Hideaki Omura said efforts are being made to ensure athletes are comfortable.

“If there are different opinions, then we will respond to them appropriately,” Omura, who also serves as governor of Aichi prefecture, told the AFP news agency.

“At this point, while we are responding to individual opinions, we have been improving everything as issues arise, and we will continue to respond that way.”

He added that a committee of former athletes, including Olympians, gave a favourable assessment of the plans for the huts built this year.

“We explained everything to them and had them take a look around, and they said it looked functional and good,” he said.

Where will the Asian Games athletes stay?

Alternative housing options range from a cruise liner and wooden containers to hotel rooms.

On Tuesday, the Italian cruise ship, Costa Serena, which will host 4,000 athletes and officials, arrived in Nagoya.

The shipping container-style huts in the dock area of Japan’s biggest port will host 2,000 other athletes and officials.

On Thursday, Japan’s deputy Chef de Mission Hisashi Mizutori told a news conference that athletes have been going through entry procedures since the cruise ship village opened a day earlier.

“There have been cases where coaches, team officials and athletes have been assigned to the same room. There are also situations where room assignments were made purely based on the numbers, such as assigning five twin rooms for a group of five men and five women,” Mizutori said.

“While the numbers match on paper, practically it creates challenging situations such as men and women being assigned together, coaches being assigned with athletes, or trainers who need to accommodate a lot of medical equipment being assigned together.”

He added that the Japanese Olympic Committee (JOC) had also anticipated accommodation “challenges” and secured hotels in the city as a backup.

“We are currently working to coordinate and negotiate adjustments wherever possible. For cases where that proves too difficult, we are considering using the backup accommodations that Team Japan prepared in advance as alternatives.”

Why are participating nations and athletes complaining about the accommodation?

Jung Jae-yong, vice president of the Korea Basketball Association (KBA), slammed the cabins hosting the men’s basketball team.

“Athletes who are over two metres tall cannot even stretch their legs out on the beds. It’s unreasonable.”

Jung also accused the organisers of failing to respond to South Korea’s concerns about the housing options.

“The organisers have still not said anything,” he said, adding: “We are very concerned and discussing extensively with the Korean Sport and Olympic Committee what to do about this.”

Player Byeon Jun-hyeong, from the basketball team, posted a video on social media showing a leaking sink and a soaked floor in his hut.

“Please help us,” he posted.

Philippine Olympic Committee president Abraham Tolentino also said that while all his athletes had been given a room, “some officials, like coaches, were moved to different hotels and Airbnb”.

Why will cricketers get the best accommodation at the Asian Games?

Head of Japan’s cricket association, Naoki Alex Miyaji, said in early September that cricket would get better accommodation than other sports.

According to Miyaji, the cricket tournament is being run by the Asian Games organising committee in collaboration with the Asian Cricket Council.

He said that the two bodies had been discussing accommodation options “for a long time”.

“The participating teams in cricket are being offered hotel accommodation,” Miyaji said.

“Many other sports are being accommodated in much more limited facilities, such as a cruise ship or container hotels.”

What other issues have hit the Asian Games?

While the opening ceremony has yet to take place, several events such as basketball, football, cricket, hockey and modern pentathlon have already begun.

On Thursday, Tropical Storm Dujuan was located off Japan’s Pacific coast as of 03:00 GMT and heading northwest towards central Japan, where Nagoya is located.

Last week, torrential rains hit Nagoya and the surrounding areas, forcing schools to close and suspending train services. Several hundred athletes were also forced to leave their accommodation.

Kosei Inoue, Japan’s chef de mission for the Games and a senior executive board member of the JOC, said at a news conference on Thursday that some competitions have already experienced “delays or postponements, and there is also a possibility that a typhoon could approach on September 21”.

“Under these circumstances, we are holding thorough meetings within the JOC to ensure that we are fully prepared and capable of responding appropriately to these situations.”
