Iwanami Shoten was founded in 1913 by Shigeo Iwanami. Its first major publication was Natsume Sōseki's novel Kokoro, which appeared as a book in 1914 after being serialized in the Asahi Shimbun. Iwanami has since become known for scholarly publications, editions of classical Japanese literature, dictionaries, and high-quality paperbacks. Since 1955, it has published the Kōjien, a single-volume dictionary of Japanese that is widely considered to be authoritative.
