Traveling from Onomichi to Yokohama primarily involves using the Sanyo Shinkansen and the Tōkaidō Shinkansen. The trip typically starts with the Sanyo Shinkansen, where you can take either the Hikari or Kodama services. The initial leg of the journey on the Hikari Shinkansen can reach speeds of up to 285 km/h (177 mph) and takes about 1 hour and 30 minutes to reach stations like Hiroshima and then onward to Shin Kobe. From there, passengers transfer to the Tōkaidō Shinkansen, which speeds up to 300 km/h (186 mph) on the way to Yokohama, completing the trip in approximately 2 hours and 50 minutes depending on the service chosen. While the Kodama service travels at a slightly reduced speed and makes more stops, the Hikari and Nozomi are preferred for faster travel times. Both train types offer comfortable seating options, and amenities such as food carts and restrooms, allowing for a pleasant journey across this scenic route.
