The journey from Akashi to Kagoshima is primarily served by the Shinkansen, specifically the Sakura and Mizuho services. The Mizuho Shinkansen is the fastest option, operating at speeds up to 300 km/h (186 mph) and covering the distance in approximately 3 hours and 50 minutes with fewer stops along the route. It runs on the Sanyo Shinkansen line, connecting major cities, including Okayama and Hakata, before reaching Kagoshima.
On the other hand, the Sakura service, while also part of the Sanyo Shinkansen, makes additional stops, which increases travel time to about 4 hours and 30 minutes. The Sakura offers a balance of speed and accessibility to smaller towns that the Mizuho may skip.
Both services provide standard and Green class seating, with comprehensive onboard amenities such as power outlets and food options. The Mizuho is recommended for those prioritizing speed, whereas the Sakura is better suited for travelers who wish to explore more regional locations along the route.
