Rironsha was founded in 1947 with the desire to "sow rich seeds" amidst the devastation of the post-war era. Since then, the company has continued its publishing activities, focusing on children's literature and YA literature, nurturing the hearts of children who will lead the new era. From these efforts, numerous long-selling children's books, such as the "Boku wa Osama" series, and masterpieces passed down through generations have been born. Currently, Rironsha continues its activities with the slogan, "Books that help children grow into adults. Books that help adults return to being children."
