In his early childhood, he was called a "child prodigy." However, the death of his younger brother when he was eight years old awakened him to literature, and he subsequently left his formal studies behind to immerse himself in writing poetry. He was deeply devoted to the French symbolist poets Rimbaud and Verlaine, studying French at the Tokyo School of Foreign Languages while also working on translations of their works. His poetry is characterized by a beautiful, melody-like rhythm tinged with melancholy and a delicate sensibility expressed through everyday language (colloquial speech). He was very short, standing about 150 cm tall, and in his private life, he was a lonely person.
His friend, the critic Shōhei Ōoka, recalled that he "looked like a doll." Because he was small and had delicate features, he had a boyish charm when he was sober.
Sober (when not drinking): Extremely sensitive and polite.
Heavily intoxicated (when drinking): Feared as one of the literary world's worst "violent drunks."
Reason he was loved: Despite causing so much trouble for those around him, he was never completely cut off because of the overwhelming beauty of the poems he wrote and his endearing, human side that would meekly apologize the next morning, saying, "I'm sorry about yesterday."
His first-person pronoun was "boku": Based on letters to his mother and wife, Chuya consistently used "boku" towards women, both in letters and verbally. This was a sign of his good upbringing and his psychological desire to show dependence and sincerity towards women.
Personality: "Clingy" and "Intensely Jealous"
[Source/Testimony] From the memoirs Blind Autumn by Yasuko Hasegawa (former live-in partner/lover): Yasuko Hasegawa, the actress he lived with in his teens, recalled Chuya's kindness when he was sober. When Yasuko was bedridden with a cold, Chuya nursed her attentively, grating an apple and feeding it to her. When Yasuko said, "Chuya, this is delicious," Chuya was overjoyed, replying with a boyish smile, "Is that so? That's because I grated it." Furthermore, Yasuko testified about Chuya, saying, "He clung to me like a child searching for its mother's breast," showing that he sought a strong maternal love.
The flip side: "Intense Jealousy and Possessiveness" [Source/Testimony] From Songs of Bygone Days by Shōhei Ōoka (friend/author) / Testimony of Hideo Kobayashi (critic): When Yasuko abandoned Chuya and went to his best friend Hideo Kobayashi, Chuya's jealousy turned into madness. Chuya broke into their shared home in the middle of the night, sat down beside their futon, and relentlessly berated them. Hideo Kobayashi later described the scene: Chuya cried and screamed all night long, "What are you going to do with me?!" and "You two have betrayed me!", continuing to rail against them.
