Why Buy a SIM Card For Japan?

In today’s age, a smartphone is an essential travel companion. It helps you translate that tricky kanji on a menu, navigate through Tokyo’s bustling streets, find a local date or instantly share your trip highlights on Instagram.

    Buying a SIM Card For Japan – Things To Consider

    But there’s no one-size-fits-all solution when it comes to choosing the right SIM cards for travelling Japan. Let’s delve into the vital considerations for choosing a SIM card in Japan.


    While everyone loves a good deal, don’t let a cheap initial package fool you. Sometimes, the initial cost might be low, but the subsequent top-ups might burn a hole in your pocket. For instance, some providers may offer a SIM for just ¥1000, but data top-ups could cost a lot more.


    Monitor your daily data usage before your trip and consider that you might well use a lot more while travelling. For instance, streaming the cherry blossom festivals might use more data than you anticipate, as will having to translate more or less every conversation…


    Japan is a surreal mix of urban cities and rural landscapes. While Tokyo might have impeccable internet coverage, the remote villages in Kyoto might not. Research is pivotal here so know precisely where you will be staying in Japan, and try to find a provider who offers a good level of courage across all of these areas and regions.


    Acquiring a SIM in Japan is usually a seamless process, but always be ready with your identification just in case.


    Always check the SIM’s lifespan. If you’re in Japan for a 3-month internship, ensure your SIM doesn’t expire before that. Many tourist-friendly SIMs have a 7, 14, or 28-day lifespan on them.

    The Future of the SIM Card is HERE!

    A new country, a new contract, a new piece of plastic – booooring. Instead, buy an eSIM!

    An eSIM works just like an app: you buy it, you download it, and BOOM! You’re connected the minute you land. It’s that easy.

    Where To Buy a SIM Card For Japan?

    You may already know that Japan is something of a capitalist, consumerist mecca, and there is no shortage of places to buy things. As such, Japan offers an abundance of places to purchase a tourist-friendly SIM card:

    In case you don’t know what an eSIM is, it’s an electronic, non-physical SIM; a SIM card without a SIM card. Instead of opening up your phone, and slotting in a new tiny little plastic SIM, you simply download the e-SIM package onto your phone just as you would an app or piece of software.

    Pre-flight purchases is a great advantage, and for this reason, we LOVE eSIM. However, be sure that your device is eSIM compatible.

    In The Airport

    A classic option for buying a travel SIM is to buy it at the airport as soon as you land. Most modern airports have SIMs and phone kiosks sat just outside of the baggage reclaim sections offering instant, easy SIM access to travellers. Often, the staff here speak some English and will get you connected right away.

    However, everything for sale in an airport is at a jacked-up price including airport SIMs. You can usually get a much better SIM deal from a wider offering of Japanese SIM providers once you get away from the airport into the city.

    Furthermore, if you land at a peak time the airport SIM kiosks can be mega-busy.

    At a Store

    There are cell phone stores across Japan and you can find at least one in every neighbourhood inside of a major city. Then electronic stores like Bic Camera, or Yodobashi offer a wide variety of SIM cards, and some convenience stores like Seven-Eleven (7/11) sell SIM cards too. However, if you want to buy in a store do ensure that you have your passport ready for verification.

    Vending Machines

    Japan’s efficiency is evident with its tech-savvy vending machines, even offering SIM cards in certain locations. These vending machines in Japan have some very strange things on sale which we would rather not go into here…


    Purchasing online before your trip ensures you’re prepared and ready to get online upon arrival as soon as you switch your phone back on. While many Japanese-specific SIMs might not be available internationally, global providers like Jetpac are and can be bought at home.
