In a small Japanese town, Ko-Ko is appointed to the unenviable position of executioner. Knowing he must successfully perform before the appearance of the Mikado in a month's time, Ko-Ko finds a suitable victim in Nanki-Poo, who is distraught over his unrequited love for the maiden Yum-Yum. Nanki-Poo agrees to sacrifice his life if he is allowed to spend his remaining days with Yum-Yum, who is betrothed to Ko-Ko. Performed by Opera Australia at the Sydney Opera House in 1987.

Stiffelio is considered "early Verdi" to musiclogists who classify things, but, in reality, it is a final transition between the maestro's earlier (but most enjoyable) works, and the mature craftsmanship of Rigoletto. Preceded by Luisa Miller (q.v.), there is more dramatic intensity and story line than in the earlier works. The plot centers around Stiffelio, a minister, who discovers that his wife, Mina, has been unfaithful.
