Travel Sim Japan Compared With Japan Portable Pocket Wifi Rental and eSim Plans – Pros and Cons

We have personally used travel sim cards, pocket wifi devices, and eSim plans for Japan over multiple visits. As a result, we have learned the pros and cons of each option. Here are my thoughts on the advantages and disadvantages of each option.

Japan Sim Card for Tourists

Before purchasing a Prepaid Japan sim card, you need to ensure that your mobile phone is unlocked. If your phone is locked to your home network provider, you cannot use this option. If you use a major Japanese phone provider such as the SoftBank network or the NTT Docomo network, you should have reasonable phone coverage in both urban and rural areas.

Most Japan prepaid sim cards are easy to install. Most come with a sim card inserter tool, enabling you to pop out the sim card slot on your phone. If you have a single sim card phone, you must remove your home sim card, carefully store it, and then insert your Japanese sim card.

If you have a dual sim card phone, leave your existing phone sim card in the slot, and add the Japan sim card into the second slot. For prepaid data sim cards for Japan, the activation process is easy – follow the directions from the sim card provider. For sim cards in Japan with a phone number, an additional activation process usually includes verification of your identity.

Once installed, we personally find that Japanese sims are much more convenient than renting a pocket wifi device, as you do not need to recharge and carry an additional device. Using your phone as a mobile hotspot is also easy if you have a generous data allowance.

While travelling, you should purchase a backup battery so you can recharge your phone while you are out and about, but otherwise, it is set and forget. You can dispose of the Japan sim card at the end of your trip.

Japan eSim Plans for Tourists

Newer generation phones can use eSim functionality to get cheap data for your phone while travelling. First, check your phone to determine if a Japan eSim plan is an option.

For each provider we recommend in our detailed article on eSim options for Japan, they each will use either a dedicated app or, alternatively, you will receive a QR Code to activate your eSim plan. Go through the activation process as detailed by your provider, and you should quickly be ready to get started.

Pocket Wifi Rental in Japan

Pocket wifi rental units are a great easy option to use if you have a locked phone or phone without eSim functionality, don’t want the hassle of replacing your sim card in your phone or if you have a larger group who all want to use a single option to access data while you are exploring each day.

You pick it up from the rental counter after arriving in Japan, turn it on, and then log in to the wifi hotspot, generated using the supplied hotspot name and password. You will the straight away have access to data. The only downside of pocket wifi devices is that you need to recharge them each night and carry them each day as an extra item.

Most Japan pocket wifi devices come with a generous data allowance, as it is common practice for data speed to be reduced after you exceed your data allowance. For many portable wifi routers, battery life is about 6-9 hours, so you will either need to conserve your battery life, recharge the unit, or use a backup battery to ensure you have phone charge for the whole time you are out exploring.

If you prefer to rent a portable pocket wifi, I suggest you check out our Best Online Pocket Wifi Rental In Japan For Tourists article to assist you to choose the option which will suit you best.

How to Choose the Best Japanese Sim Card for Tourists

What prepaid sim card for Japan will best suit your needs? The answer to this question depends on your individual needs with considerations such as:

How long will you be travelling
What will you be using the data allowance for
How often will you need to use data
Whether you require a Japan sim card with a phone number

This article overviews the features and costs of various tourist sim card Japan options.

Data-only plans, along with apps such as Skype or Whatsapp, should suit most people. Think about setting up a Skype number so you can easily call people, and they can also easily call you.

Costs are accurate as of June 2023, but prices may go up or down depending on product pricing, exchange rate changes and various promotions offered by the different providers. This article will be periodically updated to reflect the latest prices.

Japan Sim Card FAQs

We have put together some Japan Sim Card FAQs to help you better understand the options to get cheap access to data while travelling.

Japan Sim Card vs Pocket Wifi vs eSim for Japan

The option of whether to use a physical sim card vs a Japan eSim plan vs Japan wifi rental depends on which phone you have and also whether you want to have voice call functionality.

If you have a newer generation cell phone, you can choose either a physical sim card, Japan e Sim plan or Japan pocket wifi rental options. Currently, to get voice calling functionality you will need to purchase a physical sim card, as detailed in the article above.

The physical prepaid data sim card Japan options are at similar price points to the Japan eSim options. Choosing an eSim means you don’t need to physically remove and replace the sim card in your phone. Both options require you to go through an activation process on your phone.

Renting a pocket wifi for Japan can be a simpler option, as apart from having to collect your pocket wifi for Japan on arrival at either the Airport Post Office or other collection counter, the only activation process is to turn it on, log into the wifi network on your mobile phone, and then you are ready to get started.

Also, multiple people can log into a single Japan portable wifi device, making this a good affordable option for families and groups. You then need to recharge the Japan wi fi each night, and many pocket wifi providers offer a backup battery option so you will not run out of charge each day.

At the end of your visit, you then need to return your Japan pocket wifi rental, either by mail satchel or returning it at your departure airport.

What is an eSim?

An eSim (otherwise known as an embedded Sim) is a new digital technology that enables you to set up a data only phone plan on your phone without needing to add a physical sim card. As a result, to get data access while travelling, instead of using your usually more costly home sim plan, you can instead subscribe to a pre-paid eSim plan for the country you plan to visit.

Over time expect that all phones will switch to having only an eSim for network access, and older-style Sim cards will be phased out of existence.

What phones can use an eSim?

Basically all of the modern generation phones should be able to use eSim technology. Here is a list of more popular phones that are confirmed to include eSim functionality. Note that budget versions of these phone options may not have eSim functionality
– iPhone 11, 12, 13, 14, XS, XR
– Google Pixel 3, 4, 5, 6, 7
– Samsung Galaxy S20, S21, S22, S23
– Huawei P40
– Z Flip 2, 3, 4
– and many more.
To confirm if your specific phone has eSim capability just do a quick Google search for your particular phone.

Do I Need a Sim Card in Japan?

Using your home phone plan’s international roaming option could cost you thousands of dollars and only provide you with a limited quantity of slow data. Purchasing a prepaid sim card for Japan is a great way to ensure that you have an appropriate amount of affordable phone data for your trip, and you could also choose to have a Japanese phone number if you need it.

Can I Buy a Sim Card in Japan?

After you arrive in Japan you can purchase a Japan sim card after you arrive, either in the arrival hall of your airport or at local convenience stores. A key issue is that you are likely to be tired when you arrive, and want to get through customs and immigration as quickly as possible so you can head to your hotel.

If you also need to consider options and decide which sim card to purchase that can be a lot more hassle than you need at this stage of your trip.

We recommend that you do your research into Japan sim cards in advance and pre-order your preferred option. It means you will be able to quickly stop in at the airport to pick up your pre-ordered sim card, or if you are getting one delivered to your home before you depart or to your hotel, you can head straight out of the airport an activate your sim card later.

Can I Buy a Japan Sim Card with Phone Number?

Yes, you can purchase a prepaid Japan Sim Card with a phone number. When your sim card has a Japan phone number, there is an additional activation step to confirm your identity. Our recommended Japan sim card with voice providers are either Mobal or Sakura Mobile.

If you have a dual sim phone then even if your phone is locked you will be able to use a prepaid sim card in Japan.

Can I Buy a Japan Sim Card Without Credit Card?

Most Japan Sim Card providers require you to pre-order using a debit or credit card. However, if this option is not feasible for you, you can instead draw Japanese Yen at the airport after you arrive in Japan, and purchase a prepaid sim card with cash.

Which Sim Card to use in Japan?

Choosing a sim card to use in Japan requires you to consider how long you will need the sim card and how much data you are likely to use, and your preferred delivery or collection location. These options can also be influenced by when your flight arrives in Japan.

Ensure you check the opening hours of the collection location at your arrival airport. Consider the scenario where your flight is delayed, and ensure that you will still arrive on time to collect your Japan sim card. Otherwise, choose an option that is either delivered to your home before you depart or is delivered to your hotel.

What’s Better eSim or Physical Sim?

It all depends on whether your cell phone has eSim functionality and also whether you need to have a Japan phone number. If you do not need Japan voice calling and your phone can use eSims, then in my opinion, an eSim is a better option.

You can instantly set up your eSim and get going, whereas having to pick up a physical sim card means you have an additional step after you arrive in Japan to collect your sim card at the airport. If you need a Japanese phone number, then currently, a sim card is the only option with that feature.

A great option if you live in the UK is to order your Japanese Sim Card through Mobal, as they have international delivery for both data only and voice sim cards for Japan.

I know this is the big thing in Japan and neighboring South Korea Tony. Prepaid SIM is the way to go. Noted for my trip to Japan, when I am heading that way.

Dang dude… My mother in law showed up so fast here in Fukuoka and we’re not able to have a second to think about getting a card. It’s been a pain walking around with no internet/cell for her here. Lot of missed connections when we go to see her at the hotel. 🙁 Airports make me just want to leave them as fast possible :/

  Nathan, it is one of those things where the easiest option is to plan and book ahead so you don’t have to think about it after you arrive at the airport…

Hi Anne, you’ve written that Softbank don’t offer their own SIM card but there seems to be one on Amazon. Is it actually run by someone else? I’ve also found an unlimited data card for 31 days with Japan-Rail-Pass which seems to be a great value, do you know anything about this one? It doesn’t say which network it uses of it throttles?
Thanks

  Guy, the direct Softbank option is available through Amazon. Quite a few of the other providers are offering products which use the Softbank network.
