耳元で「トカトントン」という金槌のような音が聞こえ、一切の情熱が一瞬で冷めてしまう病気

'Tokatonton' is a masterpiece of short fiction written by Osamu Dazai during the Showa period, humorously depicting the emptiness and absurdity of post-war Japan. The protagonist, a young man, was afflicted by a strange illness: whenever he tried to live 'burning with passion for something' amidst the postwar chaos, a sound like a hammer hitting, 'Tokatonton,' would echo from nowhere in his ears, instantly cooling all of his motivation.
