Spectators and officials have been urged to "pack less" to avoid any delays when arriving at venues during next year’s Olympic and Paralympic Games in Tokyo.
Tokyo 2020 organisers have issued the warning after carrying out three days of tests, where they trialed a number of security and COVID-19 countermeasures, according to Reuters.
A decision has yet to be made on whether fans will be allowed to attend venues due to the coronavirus pandemic.
But organisers are formulating a plan to ensure a safe and successful staging of the Games with the Olympics scheduled to take place from July 23 to August 8, followed by the Paralympics from August 24 to September 5.
The Tokyo Big Sight - the venue for the International Broadcasting Centre and Main Press Centre at Tokyo 2020 - hosted the three-day trials where organisers are said to have assessed various technologies to check spectators’ body temperatures.
Among those includes thermology cameras, non-contact infrared thermometers and thermometer strips, Reuters reported.
Attached to volunteers’ wrists, the strips contain heat-sensitive liquid crystals which are able to identify if they have a fever.
It is understood organisers also checked to see how smoothly spectators can pass through the inspection area and looked at how social distancing in queues could be imposed.
Forgetting to wear a mask and trying to bring an aerosol can through security are believed to be among 40 different scenarios volunteers presented security staff during the trials.
Tsuyoshi Iwashita, security director of Tokyo 2020, said more tests would be needed once COVID-19 countermeasures are ratified.
"Pack less, wait less," said Iwashita.
"We don’t want to delay the excitement, so please come with very little luggage.
"For the testing of security measures, probably this is the last one.
"As for COVID-19, when we finalise the measures, we want to check these processes.
"To do so, we will set up further types of testing occasions."
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.
Earlier this week, the Tokyo Metropolitan Government confirmed the reopening dates for two Tokyo 2020 venues.
Ariake Tennis Park is set to open to sports federations from October 25 to November 2 before public use will be granted from November 8 to February 28.
The Tokyo Metropolitan Gymnasium, which will host table tennis at the Games, will only be open to sports federations who will be able to use the main arena and the sub arena from December 21 to March 31.
