The Sea of Fertility
Ikue Osada (from the original novel by Yukio Mishima)

This is an adaptation for the stage of Yukio Mishima’s last full-length novel tetralogy by the same title. The novels tell the story of the cycle of birth, death and rebirth of a handsome young aristocrat named Kiyoaki Matsugae. The first novel, Spring Snow tells the story of Kiyoaki and his love, and of his relationship with a school friend, Shigekuni Honda. The second novel, Runaway Horses and tells of Honda’s meeting with a rightist youth who has the same mole as Kiyoaki did, while the third novel, The Temple of Dawn tells of the middle-aged Honda’s affections for a foreign princess who is Kiyoaki’s reincarnation, and the fourth novel, The Decay of the Angel tells of the aged Honda being made a fool of by a youth he adopts. The play takes Honda as its main character while shifting back and forth intricately between the four stories. For the play’s premiere, three different actors played the part of Honda at the different stages of his life.
