The Shinkansen (新幹線) is a high speed train service that is operated by JR. It is one of the fastest trains in world and sometimes called “Bullet Train”. JR has this high speed train network throughout Japan. You can save lots of your trip time by using this train system.
When you go to Kagoshima, Kyushu Shinkansen is the best way to get there. It is fast and the trains come very frequently. But if you have a time, please consider the route from Kumamoto to Kagoshima-Chuo via Hitoyoshi and Yoshimatsu on Hisatsu line (肥薩線). It is very scenic route. JR Kyushu operate very attractive trains on this route.
Ibusuki no Tamatebako (指宿のたまて箱) is limited express train that is operated between Kagoshima-Chuo (鹿児島中央) and Ibusuki (指宿). Japan Rail Pass completely cover this train with no extra charge. But there is no non reserved seat. Reservation must be required.
This is the first limited express train on this section, Ibusuki-Makurazaki line. This train runs very slow and is operated for sightseeing along the shoreline of Kagoshima inlet. This train is operated by specialized KIHA 47 series. This train has the true Japanese atmosphere. The crew attendants are on board. Since this train has been started to operate, this is one of most popular train. It is very hard to book a seat.
*I tried to book only two days after starting to sell. Five of six trips were completely sold out. One trips was too early for my schedule. So I was forced to give up!
I have received the email from JR West. They confirmed Japan Rail Pass can be used for Kyushu Shinkansen. But Japan Rail Pass can be used for only Sakura that is the second fastest train between Shin-Osaka and Kagoshima-Chuo. We cannot take Mizuho that is the fastest train between Shin-Osaka and Kagoshima-Chuo by Japan Rail Pass. JR West and Kyushu applied same fare table as Nozomi. So Japan Rail Pass does not cover even the basic fare. If you take Mizuho, you have to pay the full fare.
