First round
The match between Tochigi City and the representatives of Yamanashi Prefecture, originally intended to be Yamanashi Gakuin University Pegasus and scheduled for 22 May, was postponed the day before by the Japan Football Association after Pegasus fielded an ineligible cup-tied player in the Yamanashi Prefecture Cup final. Note that Pegasus operates functionally as YGU's second team and competed in the Yamanashi tournament alongside the YGU third team, known as Orions; the first team YGU Braves also competed in Emperor's Cup qualifiers in Tokyo Metropolis. Subsequent to an investigation, the JFA decided on 24 May that YGU Pegasus would be disqualified and awarded their spot to Nirasaki Astros, their opponents in the Yamanashi final.

Also postponed was the match between Tonan Maebashi and Juntendo University after an individual affiliated with Juntendo tested positive for COVID-19. The match was eventually rescheduled for 5 June.

Third round
The third round schedule was announced on 17 June 2021.

Quarter-finals
A draw was held on 24 September 2021 to determine the matchups of the quarter-final stage and onwards. Nagoya Grampus was guaranteed to have home advantage in quarter-finals as they advanced to the quarter-finals of the 2021 AFC Champions League, while Urawa Red Diamonds, Kashima Antlers and Oita Trinita were drawn as the away team in quarter-finals as they could not guarantee their home stadium at the moment.
