This coin was dedicated to the participation of Portugal in the Olympic Games in 2020 in Tokyo. Initially was planned to issue it in 2020 but was postponed and became a part of the numismatic programme of 2021. The 2020 Summer Olympics, officially known as the Games of the XXXII Olympiad and commonly known as Tokyo 2020, is an international multi-sport event. Originally scheduled to take place between 24 July and 9 August 2020, it was postponed in March 2020 as a result of the COVID-19 pandemic. It is the second time that Tokyo has hosted the Summer Olympic Games, the first being in 1964. It is also the first city in Asia to host the Summer Olympic Games twice, and overall the fourth Olympics to be held in Japan, which also hosted the Winter Olympics in 1972 (Sapporo) and 1998 (Nagano).
