Mishima wrote wildly different genres, many of which are obscure to someone who is not steeped in traditional Japanese culture. The title of this play, for example, "Dōjōji" is also the title of a famous Noh play, one of the very few Noh plays to use a substantial prop: a large bell.
This play too features a substantial prop, a very large wardrobe, large enough to live in, with "the outline of a bell carved into the huge doors".
Set in the turbulent upside-down years following World War II, this unbelievably capacious wardrobe (large enough for a double bed, and capable of being locked from inside or outside) represents an invisible powerful family whose status has fallen, and onstage we see a few wealthy individuals who have the cash ready to purchase a status symbol: "a wardrobe which transcends all normal practical use."
Only one character is named, Kiyoko, a dancer. She is beautiful, the object of attraction and insinuations, as well as a figure of tragedy (youth and beauty do not guarantee happiness). Her boyfriend, also very beautiful, meets the fate which ensnares most of Mishima's handsome young men.
I suspect that if I knew more about Japanese culture, I would see more reflections and resonances in this stylized play, one of “Mishima’s modern Nō plays”.
