Travelers on the Fukuyama to Iwakuni route have a couple of options, primarily served by local trains and the Shinkansen network. The primary service available is the Sanyo Line, which operates local trains reaching speeds of around 70 km/h (43 mph). This service takes approximately 1 hour and 45 minutes to complete the journey, making several stops along the way, including at Onomichi and Mihara stations. For those seeking a faster alternative, the Sanyo Shinkansen can also be utilized by taking a local train from Fukuyama to a nearby station like Himeji and then transferring to the Shinkansen, which can travel at speeds of up to 300 km/h (186 mph). However, this option may require additional travel time due to transfers and scheduling. Overall, while the local Sanyo Line offers a direct route, utilizing the Shinkansen could provide a quicker but less direct experience. Each option presents unique advantages depending on travel preferences and schedules.
