Travel between Kobe and Onomichi is primarily serviced by the Sanyo Shinkansen and the local train services. The fastest option is via the Sanyo Shinkansen, specifically the Nozomi service, which can reach speeds of up to 300 km/h (186 mph) and connects through key stations. The journey takes approximately 1 hour and 30 minutes, making it the quickest route available. However, travelers may need to transfer to a local train at Mihara to reach Onomichi, adding roughly 15 minutes to the overall travel time.
Alternatively, the local JR San'yō Main Line offers a more leisurely option. Trains on this line operate at lower speeds, typically around 70 km/h (43 mph), and the direct trip from Kobe to Onomichi takes about 2 hours and 15 minutes. While this option is longer, it does provide a scenic experience through the Seto Inland Sea region.
For those prioritizing speed, the Sanyo Shinkansen is the best choice, but if you prefer a more immersive journey with fewer transfers, the local service offers its own charm.
