First time

first time I take train is when I invited to visit Japan.
In Bali we don't have train for public transport  and in Java island have train but  I never use it.
When I visited Japan Yamaguchi San pick up me at Narita airport and from there we take train to Kanagawa Yokohama his home town.
Japan have a very good railway system and most Japanese people take train to travel city to city's or states to states. That time Yamaguchi San help me how to buy tickets from vending machine and how to use it really very easy and convenient.
