The most economical way is to take the overnight bus. The overnight bus in Japan usually is quite comfirtable. But to my surprise, my mother had decided to come with me which I did not know.
A young and good looking man like me (who said that?) would quite be ok with the bus journey, but probably it is too hard for my mother. So, I decided to take a sleeper train.
Sleeper train in Japan used to be called "blue train".

But the one we took was the new generation of the sleeper.
When a beautifully colored 14coaches overnight train "Sunrise Express" appeared at the platform number 9 in Tokyo station, I was quite excited.

Well, this can not be called "blue train" anymore, can it?
A 900 kilometre journey was about to start...
