Background The Tokyo 2020 Summer Olympic Games (23 July–8 August 2021) were held in the middle of Japan’s fifth wave of COVID-19, when the number of cases was on the rise, and coincided with the fourth state of emergency implemented by the host city, Tokyo. Aim This study aimed to assess whether the hosting of the Games was associated with a change in the number of COVID-19 cases in Japan using a synthetic control method. Methods A weighted average of control countries with a variety of predictors was used to estimate the counterfactual trajectory of daily COVID-19 cases per 1 000 000 population in the absence of the Games in Japan. Outcome and predictor data were extracted using official and open sources spanning several countries. The predictors comprise the most recent country-level annual or daily data accessible during the Games, including the stringency of the government’s COVID-19 response, testing capacity and vaccination capacity; human mobility index; electoral democracy index and demographic, socioeconomic, health and weather information. After excluding countries with missing data, 42 countries were ultimately used as control countries. Results The number of observed cases per 1 000 000 population on the last day of the Games was 109.2 (7-day average), which was 115.7% higher than the counterfactual trajectory comprising 51.0 confirmed cases per 1 000 000 population. During the Olympic period (since 23 July), the observed cumulative number of cases was 61.0% higher than the counterfactual trajectory, comprising 143 072 and 89 210 confirmed cases (p=0.023), respectively. The counterfactual trajectory lagged 10 days behind the observed trends. Conclusions Given the increasing likelihood that new emerging infectious diseases will be reported in the future, we believe that the results of this study should serve as a sentinel warning for upcoming mega-events during COVID-19 and future pandemics.
Effect of the Tokyo 2020 Summer Olympic Games on COVID-19 incidence in Japan: a synthetic control approach

Concerns and controversies at the 2020 Summer Olympics
A number of concerns and controversies arose leading up to the 2020 Summer Olympics, which took place in Tokyo, Japan. The games were postponed until July 2021 as a result of the COVID-19 pandemic. The IOC stated that their Japanese partners and the former prime minister Shinzo Abe "made it very clear" in 2020, "that Japan could not manage a postponement beyond next summer [2021] at the latest".[1] Just weeks before the opening of the Tokyo Olympics, honorary patron Emperor Naruhito was said to be "extremely worried about the current status of coronavirus infections",[2] and was "concerned that while there [were] voices of anxiety among the public, the holding (of the events) may lead to the expansion of infections".[3]
Opposition in Japan to the Olympics during the COVID-19 pandemic
Little is known about the responses of citizens toward sporting mega-events held during a period of extended disasters, such as the 2020 Olympics held during the COVID-19 pandemic. This study aims to clarify the factors affecting citizens’ attitudes by testing the following hypotheses: the perception of high cost, the burden on medical institutions, and high risk of infectious disease spread negatively affect attitudes, while the perception of pandemic countermeasures, economic benefits, and athletes positively affect attitudes. Based on an online survey of 800 citizens before the 2020 Olympics, the hypotheses were tested using logistic regression models with the extracted factors as the explanatory variables and the attitude toward the Olympics as the objective variable. The test results confirm the factors lineated by the hypotheses, except for the perception of high cost. The fear of a healthcare system collapse from the medical burden of dealing with an outbreak has an especially strong negative effect on the attitude toward the Olympics. These results have important implications for city governments and municipalities and suggest that they should not underestimate citizens’ perceptions and attitudes when organizing mega-events and formulating proper communication. Further, the results may offer insights for the smooth strategic planning of large-scale events during unprecedented disasters.

Asian Games in Japan Leave Questions of Legacy – Adnkronos English
Nagoya, Oct. 5 (Jiji Press)–The first Summer Asian Games held in Japan in over three decades left behind questions of its legacy. The 16 days of sport mainly held in the central prefecture of Aichi through Sunday featured venues full of cheering crowds and scenes of excitement shared by a wide range of people, a sharp contrast to the spectatorless Tokyo Olympics in 2021 during the COVID-19 pandemic. The Asian Games brought together over 15,000 members of delegations from 45 countries and regions. Japan rewrote its record high for both total medal tally and gold medal count for the quadrennial sporting tournament, sweeping up 269 medals, including 83 golds. Japan left behind valuable memories for people in the country. Spectators witnessed high-level performances by athletes, and were introduced to Asia’s vast array of cultures. People also had a chance to see athletes at public events to celebrate the medalists. The 2021 Olympics and Paralympics in Tokyo had 1,423.8 billion yen in costs. The budget for the Asian Games and the Asian Para Games totaled 298 billion yen, despite the number of sports and participating athletes being larger than those of the worldwide sporting festival. The latest Asian Games aimed to create a sustainable event that was simple yet smoothly operated. The organizing committee decided not to newly build an athletes’ village, while opting to host individual sporting events at existing venues in five Japanese prefectures, including Tokyo. The massive sporting event, however, was not without its hiccups, especially in terms of operations. The event was hosted without the involvement of a major advertising agency taking charge of daily operations, which was unusual for a major international tournament in Japan. Without the know-how of such a company, many staff members on the organizer’s side were inexperienced. “There were operational difficulties from the very start,” a senior official of the organizing committee said. An event planning company tasked with venue operations failed to submit venue diagrams in time, according to a person familiar with the matter. “There was a lack of information sharing,” the person said. The person said that preparations dragged on until just before the opening ceremony, due to expense calculations and venue-related planning being delayed. Issues also plagued the tournament after competitions kicked off. North Korea’s national anthem was played instead of South Korea’s anthem at a men’s hockey match against Bangladesh on Sept. 18, while a bus did not arrive to take the South Korean men’s basketball team to a practice session before the final against Japan on Sept. 20. The organizing committee spent a busy period apologizing and explaining these blunders. While the committee had touted strong ticket sales, many spectator seats were empty at some venues. The committee also learned valuable lessons from its delayed responses to inaccurate posts being spread on social media. The committee was quick to act on some issues. An official of the committee said that it had provided round-the-clock support to tackle reports of water leaks, clogged drain and other issues by people staying at container houses serving as accommodation for athletes. On transportation issues, the committee switched to a booking system that did not accept late bus reservations after a predetermined deadline. Junichi Kawai, commissioner of the Japan Sports Agency who has plenty of experience competing at international tournaments as a six-time Paralympian with 21 Paralympic medals in swimming under his belt, said, “We always have issues” at any big tournament. “We’ve resolved them.” The Japanese government plans to put together the country’s accumulated know-how on running a massive sporting tournament, and pass such lessons on to future generations. Japan’s basic law on sports, revised last year, stipulates that efforts securing the transparency of tournament operations and nurturing personnel are state-led measures. As part of the effort, the Asian Games organizing committee needs to leave behind reports and people with related knowledge and experience. In terms of revenues, the tournament’s sponsorship income reached 27 billion yen, exceeding the organizing committee’s goal. The legacy of the latest Asian Games is the method of cutting down on expenses through utilizing container hotels and cruise ships in place of a dedicated athletes’ village, as well as ways to deal with challenges involving the transportation of athletes. Such a legacy will be very important given that Japan may host another massive sporting tournament, including possibly another Olympic Games, in the future. A committee was launched in September to submit a bid to host the 2035 Rugby World Cup. END [Copyright The Jiji Press, Ltd.]
