I went back to Japan last week for a vacation, and went to Tohoku as short trip.
Our main objective is to take Shinkansen to go to Tohoku area because my little kid loves Shinkansen, he had watched a Shinkansen DVD everyday in Jakarta here.
Tohoku Shinkansen is a bullet train from Tokyo to Aomori, and this bullet train can get over 320km/h which is fastest all over the world at this moment.
Also I and my wife likes Shinkansen because we definitely are affected from my kid. Because my kid watched DVD everyday, my wife and I also could remember a lot of information of Shinkansen.
We enjoyed Shinkansen and Onsen hot spring in Japan, that makes me so refresh and fullfiled.
