Fukuoka, Kumamoto and Kagoshima by Shinkansen
You want to see southern Japan in one line, and wonder how much time is spent on trains.
Trains, roads and flights
Fly or ride to Kagoshima and Kumamoto
You are weighing a short flight south against a long ride on the Kyushu Shinkansen.
Fly if you start in Tokyo or Osaka and head straight south. Take the Kyushu Shinkansen once you are inside Kyushu, or if you add stops on the way. The trains are kinder with luggage, and the flight wins on a long single leg.
When does flying win?
JNTO says air travel is the fastest option from Tokyo and Osaka to Kagoshima, and Kagoshima Airport is Kyushu’s second-largest, with domestic and international connections 1.
By rail, the Tokaido-Sanyo Shinkansen takes a little over five hours from Tokyo to Fukuoka, and you still need the Kyushu Shinkansen onward, because Kagoshima is not directly served by that route 2.
When does the train win?
Inside Kyushu. Bullet trains run through Kumamoto, with access from Kagoshima to the south and Fukuoka to the north 3, so a flight between Kyushu cities rarely makes sense.
The train also suits you when you add stops, such as Kumamoto on the way to Kagoshima. See Fukuoka, Kumamoto and Kagoshima by Kyushu Shinkansen.
How do bags change the choice?
Domestic flights have their own baggage allowance, which differs from your international ticket. Low-cost carriers charge extra for checked bags.
Read domestic baggage vs international allowance and domestic LCC baggage rules. On the train, large suitcases follow the rail operator’s size rules.
How do airport transfers count?
A flight saves hours in the air but adds time to get to the airport, check in and collect bags. Count both ends before you compare.
A train usually leaves from a station in the city centre. For a short leg with children or elders, the station may be easier than the airport.
How do you decide?
- Where do you start: Tokyo or Osaka for a flight, Fukuoka for a train.
- How many bags, and are they oversized?
- Do you add stops on the way?
- How tired will the group be at that point?
If you start far north and go straight to Kagoshima, fly. If you start in Fukuoka or want to stop in Kumamoto, ride. For Kumamoto’s sights, read the Kumamoto page, and for Kagoshima, Sakurajima stays. Compare with Tokyo to Fukuoka flight vs Shinkansen.
If you are choosing between a flight and the Kyushu Shinkansen, send your start city, bags and stops, and we compare the two for your group.

Questions travellers ask
Is flying to Kagoshima faster than the train from Tokyo?
Yes from Tokyo and Osaka, according to JNTO. By rail, Tokyo to Fukuoka alone takes a little over five hours, and you still need the Kyushu Shinkansen south. After airport transfers and check-in, flying still comes out ahead for the long leg.
Should I fly or take the train once I am already in Kyushu?
Stay on the train. Kumamoto and Kagoshima sit on the Kyushu Shinkansen line, so a flight inside Kyushu rarely pays off. The train also avoids airport check-in and baggage limits.
What about baggage on domestic flights?
Allowances on domestic flights differ from your international ticket, and low-cost carriers charge extra for checked bags. Check the allowance for each flight before you pack. Our baggage guides explain the main differences.
Is the Shinkansen easier with children and elders?
For many families, yes. You walk to a station, sit with luggage space and avoid airport security and bus transfers. A flight saves hours on a long leg but adds airport time. We compare both for your group.
