the sad thing is, it is not used anymore. But it is operated during 2015-2018 by the JR West.

at least it is preserved in the Kyoto Railroad Museum.


there is also a ... something related with EVA in it.

And they also have special version announcement for this train.

JR pass is quite expensive .......
and they need to reserve space for luggage in Sinkansen, making it harder to plan route.
