Natsume Sōseki (; Japanese: 夏目 漱石; born Natsume Kinnosuke (夏目 金之助); 9 February 1867 – 9 December 1916) was a Japanese novelist, poet, and scholar. He is considered one of the greatest writers in modern Japanese history and is often called the first modern novelist of Japan. Sōseki's fiction explored themes of individualism, loneliness, and the conflict between traditional Japanese values and the rapid Westernization of the Meiji era. His major works include I Am a Cat (1905), Botchan (1906), Sanshirō (1908), Kokoro (1914), and his unfinished final novel Light and Dark (1916).
Born on the cusp of the Meiji Restoration, Sōseki had a turbulent childhood, having been given up for adoption twice. He graduated from Tokyo Imperial University and became a scholar of English literature. In 1900, he was sent by the Japanese government to study in London, where he spent two miserable years marked by poverty, racial alienation, and a severe nervous breakdown. Upon his return to Japan, he succeeded Lafcadio Hearn as a lecturer in English literature at Tokyo Imperial University. In 1905, he achieved fame with the publication of the satirical novel I Am a Cat. This success prompted him to begin a prolific writing career, and in 1907, he resigned from his university post to become a full-time author for the Asahi Shimbun newspaper, a move that marked the birth of the professional artist in modern Japan.
For the rest of his life, Sōseki published a novel a year while also writing poetry and literary criticism. His work is characterized by its psychological depth, its blend of humor and pessimism, and its exploration of the human ego. Throughout his adult life, he suffered from severe stomach ulcers and recurring bouts of mental illness, including paranoid delusions, which deeply affected his work and personal life. Sōseki died from complications of his stomach condition in 1916 at the age of 49, leaving his final novel, Light and Dark, unfinished. His influence on Japanese literature is profound, and he remains one of the country's most beloved and widely read authors. His portrait appeared on the 1,000-yen banknote from 1984 to 2004.
Natsume Kinnosuke was born on 9 February 1867 in the town of Edo (present-day Tokyo), the youngest of eight children. His father, Naokatsu, held the hereditary position of nanushi (neighborhood magistrate), a prestigious and well-remunerated administrative post. However, Sōseki was born on the eve of the Meiji Restoration, a period of social upheaval that led to the abolition of his father's post and a decline in the family's fortunes. Sōseki's parents, aged fifty-one and forty-one at his birth, were ashamed of having a child so late in life and considered him an unwelcome burden.
Shortly after his birth, he was put up for adoption. His first foster parents were a couple who bought and sold used goods; Sōseki later wrote that they would leave him unattended in a basket at a nighttime bazaar. He was soon returned to his family after one of his sisters found him and brought him home. In 1870, at the age of four, he was adopted again by a childless couple, Shiobara Shōnosuke and his wife Yasu. The Shiobaras instilled in the young Kinnosuke that they were his real parents. At age six, he contracted smallpox, which left his nose and cheeks permanently scarred, a disfigurement that contributed to a sense of self-contempt throughout his life.
Sōseki lived with the Shiobaras until he was nine. His life there ended when his foster father, Shiobara, took a mistress. The ensuing domestic strife led to Shiobara leaving the house. In 1876, Sōseki's biological father, Naokatsu, reclaimed him after learning that Shiobara was planning to put the boy to work in a restaurant. Upon returning to the Natsume household, he was led to believe his parents were his grandparents. He eventually learned the truth when a maid whispered it to him one night as he lay in bed. He later recalled that his primary feeling was not one of betrayal but of happiness at the maid's act of kindness.
For years, his biological father and adoptive father engaged in a "tug-of-war" for control over him. Shiobara had legally registered Sōseki as his heir, making it difficult for Naokatsu to reclaim him fully, and Sōseki's legal status was not officially settled until he was well into early manhood. Both men likely saw the intelligent young Sōseki as an investment for their own futures. In 1888, when Sōseki was twenty-one, a formal agreement was reached. Naokatsu paid Shiobara 240 yen in compensation for "seven years of care and education", and Kinnosuke was officially re-registered as Naokatsu's fourth son. The trauma of these years left a lasting mark on Sōseki, contributing to the misanthropy and sense of alienation that pervade his writing.
Sōseki's education took a meandering path. After demonstrating early academic brilliance in primary school, he entered Tokyo Metropolitan First Middle School in 1879. In his youth, his ambitions were unfixed; he thought of distinguishing himself with his knowledge of Chinese literature, then considered becoming an architect. He disliked the emphasis on English and, in 1881, dropped out without telling his parents in order to enroll in Nishō Gakusha, a traditional academy focused on classical Chinese literature. Though this course of study was against the modernizing tide of the Meiji era, it provided him with a deep command of classical Chinese that would later enrich his writing. Realizing that English was essential for advancement, he left the academy and enrolled in an English cram school in 1883.
In 1884, at age seventeen, Sōseki passed the entrance exams for the First Special Higher School (a feeder school for Tokyo Imperial University), where classes were conducted almost entirely in English. Though he often claimed to have been an indolent student, he graduated at the head of his class. During this period, he formed a lifelong friendship with Nakamura Zekō, who would later become governor of the South Manchuria Railway and a steadfast supporter. He also met and befriended the poet Masaoka Shiki, with whom he would develop his most formative literary relationship.
In 1890, Sōseki enrolled in the English department of Tokyo Imperial University. He had initially considered studying architecture but was persuaded by a friend that it would be impossible for a Japanese architect to create a work as ambitious as St Paul's Cathedral. He felt lost during his university years, later describing it as a period of "agony" in which he struggled to understand the nature of English literature from a Japanese perspective. His professors included the German philosopher Raphael von Koeber and the Scottish scholar James Main Dixon. Despite his professed confusion, he published his first substantial critical essays, including one on Walt Whitman, which created a stir on campus.
After graduating in 1893, Sōseki took up several teaching posts in Tokyo but was deeply unhappy. He felt an "insuperable gap between his life and his profession" and like a fraud, doubting his own understanding of English literature. This period of uncertainty culminated in a two-week stay at a Zen temple in Kamakura in the winter of 1894–95, though the experience failed to bring him the clarity he sought. In 1895, driven by frustration and what his wife Kyōko later described as turmoil from a broken heart, he abruptly resigned his jobs and moved to a teaching position at a middle school in Matsuyama, Shikoku, a post he took to "bury himself alive". His experiences there would later form the basis for his popular novel Botchan.
In Matsuyama, Sōseki, then a highly eligible bachelor, decided to marry. In 1895, an arranged marriage was negotiated with Nakane Kyōko, the daughter of a high-ranking government official. After a formal meeting in Tokyo, they were married in Kumamoto in June 1896, where Sōseki had taken a more prestigious position at the Fifth Higher School. Their marriage got off to a difficult start. Kyōko, raised in a wealthy household, was unprepared for domestic duties, and Sōseki was an often irascible and demanding husband. Their turbulent relationship, which lasted until Sōseki's death, was marked by periods of intense conflict, particularly during his bouts of mental illness.
