Tohoku Shinkansen will be extended to Shin-Aomori on this coming December 4. The fastest train that is called “Hayabusa” will be operated on March 2011. We will have 2 round trips between Tokyo and Shin-Aomori, and 1 round trip between Tokyo and Sendai. (Please refer another post to check the timetable.)
This train will have Ordinary class, Green class and the brand new class which is called “Gran class”. The same type of service as the first class on the flight will be provided on Gran class.
If you are looking for the images of Hayabusa and E5 series, please refer this post, Gran class and all class seat of Tohoku Shinkansen E5 series and Gran class for Hayabusa, Hayate and Yamabiko image gallery.
Japan Railway did not announce that Japan Rail Pass user can take this class without the extra fare. The surcharge of this class 5,000 yen more than Green class. So the extra surcharge for Japan Rail Pass user will be expected.
On Feb 1, 2011, I confirmed that Japan Rail Pass can be used for Hayabusa. But if you take Gran Class, you need to pay the extra. Please refer this post to see the details.
