1. E-Payment Apps



Have a bulging wallet filled with credit cards, paper notes and heavy coins? Solve this problem with LINE Pay!  

LINE Pay is an e-payment platform that can be found in the dropdown menu of the LINE messaging app. Alternatively, you can download the LINE Pay app from the Play Store or App Store.

On the LINE application, you can register for a LINE Card, which can act as a credit card (See how you can do so here). After registering, you will be able to make transactions with your LINE Card as well as a barcode on your smartphone!

When you think of generosity, think PayPay! The app holds promotional campaigns to encourage e-payments! In the past, 20% cash back was given to users who used the app to shop at retail outlets! (Check out ongoing campaigns here!)

The PayPay app can be downloaded into your smartphone and used to make payments at various stores in Japan. Using PayPay for transactions is simple: let the shop scan your PayPay QR code or vice versa and your payment is complete! PayPay also allows you to transfer money to friends, split bills and earn points for each transaction at participating outlets!

You can top up your PayPay balance in a range of methods such as using your bank account, credit card and at a Seven Eleven ATMs (look at other top up methods here)!

With PayPay, I no longer need to bring my wallet with me as I can make transactions with my smartphone. This is somewhat safer as I am no longer afraid that I will lose my wallet. Besides, I no longer need to visit the ATM frequently or bring lots of cash around as well. Transactions have now become easy and swift. However, PayPay is not accepted at all places. Examples of such places include vending machines, train ticket machines and some small shops. In addition, e-payment apps on smartphones are not very safe. If someone gets hold of my phone, they can easily withdraw money from my bank account, and this can be done much more easily than if they had my bank card.

If you stay in Japan, you will definitely have used the public transportation system. And the familiar “beep” “beep” “beep” sound will ring in your ears whenever you pass through the ticket barriers. 

So… What are those beeping sounds? 

When locals touch their IC cards on the ticket barriers, a beeping sound is produced and the ticket fare is immediately deducted from their IC card. An IC card is another form of e-payment system that is used mostly for the public transportation system in Japan. It is sometimes also accepted by taxis, certain shops and vending machines. The IC card that students find most convenient is Suica as it comes in two forms - a physical card or a digital card that can be linked to your smartphone! 

A physical Suica card can be issued at a JR ticketing machine at a cost of 500 yen. The physical card can be linked to your smartphone if you have Google Pay or Apple Wallet installed. However, this feature is only limited to smartphones purchased in Japan, any iPhone 8, iPhone 8 Plus or newer models. There is also a Suica application that can be downloaded in both Google Play and the App Store.

“Suica linked to Apple wallet is really straight forward. You simply place the iPhone on top of the Suica card, and it’ll automatically transfer itself into Apple wallet. At the ticket gates, all I have to do is touch my phone to the IC card reader, which is really convenient since my phone is usually more easily accessible than my wallet (where I’d normally keep my physical Suica card). Additionally, Suica can be used to pay at convenience stores, so it’s a lifesaver when I’m not carrying cash. You can transfer money from other cards (in your Apple wallet) onto the Suica in the wallet app, so I don’t find that downloading the designated Suica app is necessary.”
- Mia Maetani, The University of Tokyo

Suikakeibo (スイ家計簿)


If you do not possess a Japanese smartphone and are unable to use a digital Suica card, checking your IC card’s balance might be a bit of a hassle. However, with Suikakeibo you no longer need to make multiple trips to the ticketing machine to enquire your balance. You can check your IC card’s balance by holding your Suica card on top of your smartphone until it vibrates. Thereafter, the app will display your IC card’s balance as well as your transaction history.

4. Transportation Apps

Besides Google Maps and Apple Maps that you have always been familiar with, there are other local applications that can help you navigate your way through Japan. 

Tokyo Subway Navigation


Tokyo Subway Navigation is a free application provided by Tokyo Metro Co., Ltd that allows users to search for their departure and arrival station. The system then generates a list of routes that the passenger can take to get to their destination.

Japan Travel


By entering your point of departure and arrival, Japan Travel’s algorithm will generate routes that can be taken to arrive at your destination. The routes could include travelling by train, airplane, taxi or ferry! You don’t need to worry about getting lost as detailed information such as platform numbers, station lists, and timetables will be provided as well!

That’s not all the app has to offer! You can also search for free Wi-Fi hotspots, ATMs, and train stations - all these while you are offline! 

“It is undeniable that Japan’s transportation system is ridiculously complicated, but Navitime’s English app “Japan Travel” will resolve all your traveling problems. The app allows you to find free Wi-Fi hot spots, ATMs, train stations and you can even plan your itinerary! However, my all-time favorite function is the Route Search which allows me to see my train route complete with train arrival time, duration of the trip and even the cost of travel. It also allows you to set your departure or arrival time, so you can see what time you need to get ready and leave your house - which is a lifesaver for planning your agenda!”
