Concerns and controversies at the 2020 Summer Olympics There have been concerns and controversies about the 2020 Summer Olympics, which will be hosted in Tokyo, Japan. There have been allegations of bribery in the Japanese Olympic Committee's (JOC) bid for the Games, of plagiarism in the initial design for the Games' logo, and of illegal overwork by dozens of companies involved in construction for the Games. Notable safety concerns for athletes have included radiation levels from the Fukushima Daiichi nuclear disaster, water quality, and expected heat levels. Political controversies include the use of maps which include disputed territories as part of Japan and a refusal to ban the rising sun flag at Olympic venues, and more recently the ongoing coronavirus outbreak that had originated in Wuhan in mainland China. Organizational issues and controversies Bribery and corruption In January 2016, the second part of a World Anti-Doping Agency (WADA) commission report into corruption included a footnote detailing a conversation between Khalil Diack, son of former International Association of Athletics Federations (IAAF) President Lamine Diack, and Turkish officials from the Istanbul bid team. A transcript of the conversation cited in the report suggested that a "sponsorship" payment of between US$4 million and 5 million had been made by the Japanese bid team "either to the Diamond League or IAAF". The footnote claimed that because Istanbul did not make such a payment, the bid lost the support of Lamine Diack. The WADA declined to investigate the claim because it was, according to its independent commission, outside the agency's remit. In July and October 2013 (prior to, and after, being awarded the Games), Tokyo made two bank payments totaling million to a Singapore-based company known as Black Tidings. The company is tied to Papa Massata Diack, a son of Lamine Diack who worked as a marketing consultant for the IAAF, and is being pursued by French authorities under allegations of bribery, corruption, and money laundering. Black Tidings is held by Ian Tan Tong Han, a consultant to Athletics Management and Services—which manages the IAAF's commercial rights and has business relationships with Japanese firm Dentsu. Black Tidings has also been connected to a doping scandal involving the Russian athletics team. Japanese Olympic Committee (JOC) and Tokyo 2020 board member Tsunekazu Takeda stated that the payments were for consulting services, but refused to discuss the matter further because it was confidential. Toshiaki Endo called on Takeda to publicly discuss the matter. Massata Diack denied that he had received any money from Tokyo's organizing committee. The International Olympic Committee (IOC) established a team to investigate these matters, and will closely follow the French investigation. In January 2019, a source revealed that Takeda was being formally investigated over alleged corruption. On the 19 March 2019, Takeda resigned from the JOC. In November 2019, it was reported that the Tokyo's Olympic bid committee's accounting documents, detailing over 900 million yen (≈ million US$) spent on overseas consultancy firms for Tokyo's 2020 Olympics hosting bid, were missing. Logo plagiarism The initial designs for the official emblems of the 2020 Summer Olympics and Paralympics were unveiled on 24 July 2015. The logo resembled a stylized "T": a red circle in the top-right corner representing a beating heart, the flag of Japan, and an "inclusive world in which everyone accepts each other"; and a dark grey column in the center representing diversity. The Paralympic emblem inverted the light and dark columns of the pattern to resemble an equal sign. Shortly after the unveiling, Belgian graphics designer Olivier Debie accused the organizing committee of plagiarizing a logo he had designed for the Théâtre
