For the opening ceremony, it was announced on 7 July 2021 that pole vaulter EJ Obiena and judoka Kiyomi Watanabe would be the flagbearers of the Philippines. However, Obiena was dropped as one of the flagbearers, after a new protocol was introduced which required flagbearers to be in Tokyo 48 hours prior to the opening ceremony. Obiena was set to arrive on 23 July, the date when the opening ceremony was scheduled to be held. Boxer Eumir Marcial was announced to be Obiena's replacement. In the Parade of Nations, the Philippine delegation was represented by six officials and two athletes. The officials wore ready-to-wear barong from the Filipino clothing company Kultura, topped off by a shawl made by Filipino fashion designer Rajo Laurel while the two athletes who served as flagbearers wore the tracksuits supplied by Asics.
