Impact of the COVID-19 pandemic Edit
The event was originally to take place on June 14, 2020. As a result of the COVID-19 pandemic, other wrestling promotions began to cancel or postpone their shows in an attempt to prevent further spreading of the COVID-19 virus. At the end of February, following recommendations by the Japanese Ministry of Health regarding the coronavirus outbreak, NJPW canceled the events between March 1 and March 15 including the promotion's Anniversary Event and the first and the second round of New Japan Cup. On March 23, NJPW also canceled the 2020 Sakura Genesis event, which was originally scheduled to take place on March 31. On April 8, NJPW canceled more events from April 11 through May 4, leading to the cancelation of both nights of 2020 Wrestling Dontaku and would also cancel the whole Best of the Super Juniors tournament as a result of the coronavirus (COVID-19) pandemic on May 6. Various wrestlers such as David Finlay, El Phantasmo, KENTA, the Guerrillas of Destiny (Tama Tonga and Tanga Loa), Jay White, Juice Robinson, Will Ospreay, Rocky Romero, and Robbie Eagles were unable to work on NJPW events due to travel restrictions because of the COVID-19 pandemic. During this time, NJPW wrestlers and staff created the NJPW Together project in order to do bring content to NJPW World with interviews and old archived matches. On May 6, NJPW announced that their Wrestle Dynasty event would be postponed to 2021, due to the effects of the 2019-20 coronavirus (COVID-19) pandemic.

It was also that the finals of the New Japan Cup and the Dominion in Osaka-jo Hall would be the first shows to allow fans into the arena, but only a third of the venue's normal capacity, after the Japanese Government lifted some restrictions on many regions in Japan. On July 11, it was announced that Minoru Suzuki would not be appearing at the event as a cautionary measure, after developing a fever, leading the match card to be changed. Suzuki had previously been tested negative for the virus and had since had no contact with any other wrestlers.
