Traveling from Onomichi to Sanyo-Onoda involves the use of the JR San'yō Main Line, which is served by local and rapid trains. The limited express service, known as the 'Shirasagi,' operates on this route and offers faster travel times compared to local trains. The Shirasagi can reach speeds of up to 130 km/h (81 mph) and covers the journey in about 1 hour and 20 minutes, making a limited number of stops at key stations along the way. In contrast, local trains take approximately 1 hour and 50 minutes to complete the same route, stopping at every station along the line. Both services provide comfortable seating, with the Shirasagi being the preferred choice for those looking for a quicker trip, while local trains may be ideal for travelers interested in sightseeing stops. The flexibility of scheduling on the JR San'yō Main Line ensures daily options for travelers.
