Tokyo is the most expensive city to live in but there are still many ways to make the trip less expensive.
As I was writing this money saving guide for Tokyo, I realized that there is just too many sub-categories so I split the tips into three different posts.
This post is about saving on transportation. There is another on food and drinks as well as accommodation and sightseeing.
Transportation in Tokyo is crazy. A short trip would cost 180 yen (US$2.3) on the train which is very expensive compared to Singapore.
From Narita Airport: Get the Suica & N’EX package

I picked up the Suica & N’EX package for 3,500 yen when I reached Narita airport. It includes transport into the city (and slightly beyond) as well as a 2,000 yen Suica.
The package also good value because the N’EX limited express train to Tokyo is 2,940 yen (gasp!).
There’s also a package with return fare.
From Haneda Airport: Get Monorail and Yamanote Line Discount Ticket

Only available on weekends
If you arrive at Haneda Airport during the weekend, remember to pick up this discounted ticket.
For just 500 yen, you can take the monorail and leave at any stations on the Yamanote Line. If you are exiting at other JR stations, just pay the extra at the counter.
Free one-way day trip with Suica & N’EX package
If you have a day trip planned to either Yokohama or Kamakura, I recommend doing it on the day you arrive if you reach before noon.
I was planning to visit Yokohama but when I found out that the package covers Kamakura, I changed my plans immediately.
A trip from Tokyo Station to Kamakura would cost 890 yen. So in theory, I’ve saved a little by heading straight there instead of taking the day trip on another day.
Transfer rebate with Suica
If you are using Suica to pay for your transport, it automatically gives you rebates when you transfer from trains of the same company.
Stick to the same company on trains

Planning your transport within Tokyo is really tricky. There are just too many lines and too many different train companies.
Many times, I had to transfer from one train line to another to reach my destination. I accidentally took different train lines for a ride and it cost me more than it would if I had transferred from the trains of the same company.
So, I suggest taking trains from the same company when you travel. This might mean an extra 5 minutes, but it’ll cost 200 yen less.
