Stations in Japan
can be vast and especially in Tokyo. But do not worry !
If you have a stroller or if your children are tired of getting off and climbing the stairs, you will find lifts and escalators.
If it is possible, it is better to avoid the crowded hours ( (7 am to 9 am is the most intense time).
In the stations, you will find many shops in which you can make last minute
purchases and bento (Boxed lunches
). They also offer small souvenirs related to the japanese train.
