Yojiro Ishizaka (1900–1986) was a Japanese novelist. One of the leading writers of postwar popular literature, he became widely known for his optimistic portrayals of youth, love, and personal growth in a rapidly changing Japan. In 1950, he received the Minister of Education's Art Encouragement Prize for "Aoi Sanmyaku" ("Blue Mountains"). His best-known novel, "Aoi Sanmyaku," follows high school students and teachers in postwar Japan, exploring democracy, gender equality, and the hopes of a new generation.
