Hello : )
Have you used a public transportation in Tokyo?
Transportation in Tokyo is quite exact (well, I think),
and is really convenient- I even think you don’t need any cars in Tokyo.
Not only the train- but the buses are also quite exact and easy to use too!
(Actually I use the bus to come to my office too!)
If you just see the road map,
you might feel dizzy- it is too complicated on the paper.
There are so many stations in Tokyo.
And especially in the middle of Tokyo,
there are many stations that you can even walk to the next station.
Since you might feel complicated on the map,
there are two tools that I really recommend!
1)route search application
Of course you can use the google map too,
but these applications are really convenient- you can know how much it will cost, how long it takes, and even shows you several routes to go to the station.
Just search 乗り換え検索 online- I’m sure you can find one!
2)SUICA / PASMO
These are a prepaid e-money card, and you can use for both transportation fee and shopping!
You just have to charge the money at the station- and then no need to buy the ticket every time you get on the train/bus, or no need to take your wallet to buy some sweets at the convenience store.
Hope this will help your life in Tokyo : )
