The date has been deduced from a list in the archive of Britten's operas performed in Japan 1953-79. This states that 'The Rape of Lucretia' was given in concert form by the Rameau Society - Niki Kai in July 1953 and again (presumably staged) in June 1954. Akeo Watanabe was the conductor and Sugisaku Aoyama the producer. There is no information concerning the cast.
