Drug addiction incidents

Yozo's morphine addiction represents the terminal phase of his long retreat from human society, a period in which the last vestiges of his will, dignity, and physical health are systematically dismantled. What begins as a seemingly benign medical substitute for alcohol rapidly becomes a consuming dependency that strips him of all capacity for resistance, plunges him into a squalid cycle of deception and degradation, and culminates in his confinement in a mental hospital—the final, official confirmation of his status as a "reject" and a being "disqualified as a human being."

The Transition from Alcohol to Morphine

The addiction is born not from a search for pleasure but from a desperate need to escape an unbearable state of being. After the traumatic violation of his wife Yoshiko, Yozo's drinking had escalated to the point where he was coughing blood, his teeth were falling out, and his body was failing. On a snowy night behind the Ginza, he vomited blood that formed a "big rising-sun flag in the snow," a visceral image of his internal decay. Staggering into a nearby pharmacy, he encountered the proprietress, a woman who stood with difficulty on crutches, her eyes filled with a longing that Yozo immediately recognized as the unhappiness of a kindred spirit. She warned him that her own husband had shortened his life by drinking despite his tuberculosis, and she offered him a substitute: morphine, which she claimed was "no more harmful than liquor." Yozo, weary of the squalor of drunkenness and overjoyed at the prospect of escape, accepted without hesitation. The first injection swept away his insecurity, fretfulness, and timidity, replacing them with an expansive optimism and fluency. He felt he had finally broken free from the devil of alcohol.

The Rapid Descent into Full Addiction

The relief was tragically short-lived. Yozo's intended single daily shot quickly escalated to two, then three, then four; he could no longer work without the drug. The very suggestion from the pharmacist woman that he might become an addict was enough to convince him that he already was one, and this uneasiness only drove him to seek more of the drug. He began to lie to her, claiming the morphine was an "energy-builder" essential for his work, and he resorted to pathetic manipulation, even kissing her to secure a supply. The relationship between them became a sordid mutual dependency: whenever she caught sight of his face, the tears came to her eyes, and he wept as well. His debt at the pharmacy grew to a frightening figure. To obtain money for the drug, he resumed copying pornographic pictures, a trade that marked the final degradation of his artistic aspirations. He had, he realized, "truly reached the extreme of shamelessness." The drug that was supposed to save him had become a foul, abominable master, fouler than the gin it replaced.

The Final Crisis and Institutionalization

As his physical and mental state deteriorated, Yozo's thoughts turned obsessively to death. He felt that no matter what he did, it would be a failure, just "a final coating applied to my shame." In a last, desperate gamble, he wrote a long letter to his father confessing his circumstances, a resolve he equated with "a bet on the existence of God." The answer never came, and his anxiety only increased the dosage. He resolved to inject himself ten times in one night and throw himself into the river. But on the afternoon of that very day, Flatfish appeared with Horiki. Horiki, with a gentle smile Yozo had never seen on his face before, said, "I hear you've coughed blood." That single, unexpected gesture of kindness shattered Yozo completely. He wept, and without any will or resistance, he allowed himself to be bundled into a car and driven to a large hospital in the woods. The young doctor with a bashful smile examined him and told him he needed to rest. The key grated in the lock behind him. He was in a mental hospital.

The Meaning of the Asylum: Disqualification

The asylum was the literal fulfillment of a delirious cry he had made after his overdose of sleeping pills: that he wanted to go "somewhere where there aren't any women." His ward held only male lunatics, and the nurses were men. It was here that the novel's central thesis was made explicit. Yozo reflected that he was no longer a criminal but a lunatic, yet he insisted, "I have never been mad for even an instant." He understood the cruel logic: people who get put into asylums are crazy, and those who don't are normal. The act of non-resistance—his passive acceptance of Horiki's smile and the car ride—had sealed his fate. He was now branded on the forehead with the word "madman" or, perhaps, "reject." The final, devastating conclusion followed: "Disqualified as a human being. I had now ceased utterly to be a human being." The morphine addiction was not merely a physical dependency; it was the mechanism that finally stripped him of all social standing and personal identity, delivering him into the hands of an institution that would officially certify his exclusion from the human race.
