Suga is set to make a policy speech to the Diet, the national legislature of Japan, on Monday (October 26).

His draft speech repeats his belief that the successful staging of Tokyo 2020 would be "proof that the human race has conquered the virus", as reported by Kyodo News. 

Since becoming Japanese Prime Minister in September, Suga has already revealed his intention to ensure the Olympics and Paralympics take place next year numerous times. 

The Olympics have been postponed to July 23 to August 8, followed by the Paralympics from August 24 to September 5, as a result of the COVID-19 pandemic. 

Organisers now have to plan for the Games against the backdrop of the global health crisis.

A coronavirus countermeasures taskforce, formed of officials from the Japanese Government, Tokyo Metropolitan Government and Tokyo 2020, is assessing possible scenarios and measures that could allow the Games to run as scheduled in 2021. 

Policies are expected to be announced before the end of the year.

These are likely to include a mechanism for lifting the entry ban on foreign tourists, which is currently in place for 159 countries and regions.

Measures may include a health-checking app, mandatory testing and health insurance and exclusive health centres for tourists.

Suga has recently identified rescuing the Japanese tourism industry as a key policy, which is likely to aid the efforts of Tokyo 2020 organisers.  

The continuing discussions surrounding countermeasures have not eased the mind of volunteers for the Games, however. 

A questionnaire conducted by the Tokyo Metropolitan Government in August has revealed that nearly 79 per cent of volunteers were worried about coronavirus.  

International Olympic Committee President Thomas Bach is expected to visit Japan next month to meet Suga, who replaced Shinzō Abe after he resigned due to ill health. 

So far, Japan has reported more than 93,900 coronavirus cases and 1,679 deaths, but is deemed to have kept the virus under control in relative terms.
