The Izumi to Yamaguchi route is primarily serviced by the Sakura Shinkansen, which operates a modern and efficient train service on this line. The Sakura train can reach speeds of up to 300 km/h (186 mph) and takes approximately 1 hour and 45 minutes to complete the journey. It makes several key stops, including Shin-Yamaguchi, which adds to the accessibility of the route.
An alternative on this route is the local Zouho limited express train, which takes about 2 hours and 30 minutes, providing a slightly slower but more frequently scheduled option for travelers.
Both services offer comfortable seating options and basic amenities, with the Sakura Shinkansen being preferable for those prioritizing speed and efficiency. In contrast, the limited express Zouho is suitable for travelers who may wish to enjoy a more leisurely trip with additional stops to explore.
