Diary of a Mad Old Man is the journal of Utsugi, a seventy-seven-year-old man of refined tastes who is recovering from a stroke. He discovers that, while his body is decaying, his libido still rages on - unwittingly sparked by the gentle, kindly attentions of his daughter-in-law Satsuko. He develops an obsession for her feet.
