Visual documentation of the restoration work on the organ of the Cathedral of Évora between 2021 and 2022 for the Japanese Association Kamakura-Portugal. The historical connection to Japan is due to the Tensho Mission, the first Japanese embassy sent to Europe in the 16th century, bound for Rome, to present itself to the Pope, who while passing through Évora and its cathedral, took a first contact and enthusiasm with the Renaissance organ of the sixteenth century that lasts until this day.
