Types and Features of Japanese SIM Cards
There are two main types of SIM cards that can be used in Japan: prepaid and postpaid. Understanding the characteristics of each and choosing the one that suits your travel style will lead to a comfortable stay.
Prepaid SIM Cards
Prepaid SIM cards are a type of card where you purchase the amount of data you need in advance, and you pay the necessary fee at the time of purchase. The big advantage of this type of card is that there is no additional charge even if you exceed the available data amount. In other words, you don’t have to worry about unexpected high charges during your trip. It is especially convenient for short-term visitors and those who do not use a lot of data.
The usage period is usually set to about one week to one month, which is suitable for short-term visits such as sightseeing and business trips. Another advantage of prepaid cards is that even if you do not use up the data you purchased, you will not feel a sense of loss.
Postpaid SIM Cards
Postpaid SIM cards are a type of card where you pay after use, and monthly contracts are the norm. This type of card has many plans with no data capacity limit, and is suitable for those who want to use the card without worrying about the amount of data. In addition, it is very convenient for travelers who stay for a long time, as they do not have to worry about purchasing procedures or adding capacity every time.
For example, this format is suitable for those who are planning to stay for several months on a study abroad or long-term business trip, or for those who plan to engage in activities that consume a lot of data, such as watching videos and online meetings. However, in many cases, a credit card is required to sign a contract, so you need to be aware of the complexity of the purchase procedure and the timing of cancellation.
How to choose between prepaid and postpaid
Which one to choose depends on the purpose and duration of your trip. If you are prioritizing convenience for a short-term tourist trip, a prepaid type is ideal, and if you plan to stay for a long time or use a large amount of data, a postpaid type is ideal. Make sure you understand the characteristics of each and choose a SIM card that suits your needs.
Where to buy SIM cards in Japan
Once you have decided on the type of SIM card, the next step is to choose a place to purchase it. There are several places in Japan where you can get SIM cards, but knowing the benefits of each and the purchasing procedure will make the arrangements smoother.
Purchase at the airport
If you want to use the Internet from the moment you arrive in Japan, purchasing at the airport is the easiest way. Major airports such as Narita Airport and Kansai International Airport have counters and vending machines that sell SIM cards for foreign travelers. These have ample English support, and you can choose a card while receiving an explanation from the staff, so even first-time visitors to Japan can purchase one with confidence.
Most SIM cards sold at airports are prepaid, and you can easily set them up on the spot. After purchasing, you can immediately insert it into your smartphone and set it up to use the Internet. In addition, plans are often available according to the length of your stay, and you can choose from a daily unit, allowing for flexible use.
Purchasing at Electronics Stores
A wide variety of SIM cards can be purchased at electronics stores. In areas where electronics stores are concentrated, such as Akihabara in Tokyo and Nipponbashi in Osaka, you can find SIM cards with various data plans and options. The appeal is that you can consult with the store clerk and choose a card that suits your smartphone’s specifications and data volume.
In addition, when purchasing in a store, you can see the actual product in your hands, which gives you a sense of security compared to purchasing online. In addition, there are sometimes campaigns and discounts, so you can sometimes get a good deal.
Purchase at an online store
In recent years, it has become popular to purchase a SIM card online and have it delivered to your designated address or accommodation. This is a convenient option, especially for those who want to prepare well before their trip. It is important to order well in advance of your schedule, as delivery may take some time.
How to purchase a SIM card in Japan
Once you have decided where to purchase a SIM card, it is important to know the specific purchase procedure. If you understand each purchase method well, you will be able to set up an Internet environment smoothly.
How to purchase at the airport
If you purchase at the airport, the procedure is relatively simple. First, find a counter or vending machine that sells SIM cards. At these counters, staff often speak English, so you don’t have to worry about the language barrier. You may be required to **present your passport** when purchasing.
Specifically, the process is as follows.
– Tell the staff at the counter what plan you want (data capacity and period).
– Read the explanation provided by the staff and choose the best plan.
– After making the payment, you will receive the SIM card and insert it into your smartphone on the spot.
– In many cases, staff will help you set it up, and you can start connecting to the Internet on the spot.
Purchasing at the airport is a very convenient method for travelers visiting Japan for the first time, as it can be used immediately after purchase.
How to purchase at an electronics store
At an electronics store, you can choose the SIM card that best suits your needs from a wide range of options. When purchasing, it is important to consider the following points.
– Make sure that your smartphone is **SIM-free**.
– Tell the store clerk how much data you need and for how long.
– If you are particular about a particular brand or provider, make that clear.
When making the purchase, you can find a more suitable SIM card by consulting with a store clerk with specialized knowledge. In addition, stores near tourist spots often have foreign language support, and large stores in urban areas in particular have a wide range of services for overseas travelers.
How to purchase at an online store
If you want to plan and prepare in advance, purchasing online is a good option. If you are buying a SIM card from an online store, please refer to the following steps:
– Visit a trusted sales site and look for a SIM card section for foreign tourists.
– Select the data capacity and plan you need and add the product to your cart.
– Select your payment method and complete the purchase (in most cases, a credit card is required).
– Specify the delivery address and set it as your accommodation or pick-up location after arriving in Japan.
When purchasing online, it may take several days for delivery, so we recommend ordering a few days before your trip. It is also a good idea to check the start-up procedure in advance so that it can be used immediately after arrival.
