Natsume Sōseki (夏目 漱石^?, February 9, 1867 – December 9, 1916), born Natsume Kinnosuke (夏目 金之助^?), is widely considered to be the foremost Japanese novelist of the Meiji period (1868–1912). He is best known for his novels Kokoro, Botchan, I Am a Cat and his unfinished work Light and Darkness. He was also a scholar of British literature and composer of haiku, Chinese-style poetry, and fairy tales. From 1984 until 2004, his portrait appeared on the front of the Japanese 1000 yen note.

Born as Natsume Kinnosuke in the town of Babashita in the Edo region of Ushigome (present Kikui, Shinjuku), Natsume began his life as an unwanted child, born to his mother late in her life, forty years old and his father then fifty-three. When he was born, he already had five siblings. Having five children and a toddler had created family insecurity and was in some ways a disgrace to the Natsume family. In 1868, a childless couple, Shiobara Masanosuke and his wife, adopted him until the age of nine, when the couple divorced. He returned to his family and was welcomed by his mother although regarded as a nuisance by his father. His mother died when he was fourteen, and his two eldest brothers died in 1887, intensifying his sense of insecurity.^{[citation needed]}
