The train here is very on time. I only once experience that it was late because there might be something happened. I honestly dont understand what the guy saying lol. They had an announcement.

Kids is half off of adult fare. I suggest it is very easy for us to travel if we use suica or pasmo card. You just swipe it off on the entrance booth. You can recharge your card to any ticket machine. If you like to acquire a card then bring an ID to your son or a passport. Go to the window outside Yokosuka chuo station- they will only issue pasmo card. FYI, Keikyu line use pasmo card and JR line use suica.

We got Ben a card and it is very easy for us to travel by train. Mary got jealous since she can get her own card next year when she will be 6.
