Shunzō Miyawaki (1926–2003) was a Japanese travel writer and editor who established railway travel writing as a distinct literary genre. After a distinguished editorial career at Chūōkōronsha, where he helped launch the influential Chūkō Shinsho series, he devoted himself to writing travel literature centered on railways. His best-known book, "Jikokuhyō 20,000 Kilometers" ("Timetable 20,000 Kilometers"), chronicles his quest to travel every Japanese National Railways line, conveying both the pleasures of railway journeys and the fascination of planning them through railway timetables.
