In Part 2, we explore the Sanyo Shinkansen routes that connect the two largest cities in the west of the country: Osaka and Fukuoka. We explore one of the most beautiful bike routes in the world and meet a young woman in Hiroshima who keeps the stories of the atomic bomb victims alive. We look out for the Dr. Yellow, a bright yellow route checker bullet train; legend has it that fate is kind to anyone who spots it.
