When traveling abroad, one essential thing you must have is access to the internet. Even if you have a phone, it won’t be much use as most apps on your phone won’t be able to function without it. Especially if you don’t speak the language, an internet connection is essential when you want to find information about good restaurants and scenic spots nearby, and, most importantly, communicate with the locals. But a common question that most people would have is, “Japan SIM card, Japan eSIM, or Japan pocket WiFi, which one is better?” If you also have the same question in mind, read on!
Obviously, you can use international roaming, but that is usually the most expensive option. This is why most people either rent a Japan Portable WiFi or purchase a Japan SIM or eSIM.

Is There Free WiFi in Japan?
Obviously, having free WiFi to use would be the best. However, just like any country in the world, the free service is mostly only available at your accommodation, restaurants, cafes, and shopping malls. Once you leave these facilities, you will likely have no other free internet connection to rely on.
However, if you are comfortable without internet access when you are away from a hotspot, a convenient app to download is Japan WiFi Auto-Connect. The phone application automatically connects your devices to secure, trustworthy, free WiFi networks nationwide.
Tip: If you want to know where to enjoy free WiFi access in Japan, refer to Japan WiFi Auto-Connect’s WiFi Spot Map.
Important: Please refrain from entering sensitive personal information, including credit card details, while connected to a free WiFi network.
Japan eSIM vs Japan Pocket WiFi vs Japan SIM Card for Tourist
Although we would like to have access to free internet while traveling in Japan, the free network doesn’t cover the entire country, especially in rural areas, over mountainous regions, and on small islands. Some might consider international roaming, but the fee for this service can be quite expensive, and the quality of reception may vary depending on the service provider.
Therefore, most people would purchase an eSIM card, a SIM card, or rent a Portable WiFi for their Japan trip.
But is a Japan eSIM better than a pocket WiFi or vice versa? Or should I get a Japan SIM card rather than renting a Japan portable WiFi? The answer depends on how you travel, as each option has pros and cons. Refer to the Japan pocket WiFi, SIM card, and eSIM comparison table below. It should give you a clear idea of which option is best for your next Japan trip!
| Pocket WiFi | SIM Card | eSIM Card | |

Should I Get a Japan Pocket WiFi, a Japan eSIM, or a Japan SIM Card
Whether a pocket WiFi, a Japan SIM card, or an eSIM best suits your next Japan trip depends on a couple of factors. Here is a quick guide to help you make the decision.
- If you plan to travel as a larger group and the group members will stay together, a pocket WiFi might be the best choice.
- Sakura Mobile is our favorite Japan pocket WiFi provider because it uses the best network in Japan. The company’s customer service is also among the best in the industry.
- If you plan to travel as a group but also want to wander around on your own from time to time, consider getting a Japan SIM or Japan eSIM.
- Japan Wireless is our favorite Japan Data SIM card provider.
- Jetpac is our favorite Japan eSIM provider.
- If you have multiple devices that need to be connected to the internet, for example, you need to work remotely, a Japan pocket WiFi is the best option for you.
- If you need a Japanese phone number, a Japan SIM/eSIM is your only choice.
- Mobal is our favorite Japan Call + Text + Data SIM/eSIM card provider.
- If you are a heavy-data user, consider a Japan pocket WiFi or a Japan eSIM.
- Sakura Mobile has the best plans for heavy-data users.
- Jetpac is our favorite Japan eSIM provider.
- If your flight arrives/departs early or late, get a Japan SIM card from a service provider that will mail the SIM card to your home address or a pocket WiFi provider who’s airport counter opens in the early morning and until late at night. Obviously, if your phone is compatible with an eSIM, it might be the best option for you.
- Sakura Mobile‘s airport counter has the longest opening hours.
- For SIM cards, Mobal can send the SIM card to you for free.
- If you travel light, a Japan SIM card or eSIM is the best option for you.
How to Get a Japan Travel SIM and/or Portable WiFi
Both Japan Travel SIM and Portable WiFi can be pre-arranged/purchased before you land in Japan. In fact, it is better if you do so because most of the time, it will be cheaper, and you won’t be wasting your valuable travel time at the airport.
- Japan Travel SIM: Depending on where you are flying from, there is more than one SIM card provider for you to shop around.
- Be sure to examine the product’s details carefully. A cheaper SIM doesn’t necessarily mean it is a better deal.
- Once purchased, the seller might ship out the SIM to you. Therefore, it is essential to consider the required shipping time before making a purchase.
- Most Japan SIM card providers also have a counter at the airport for you to collect your purchase.
- Japan pocket WiFi: Rental can be easily done online. Again, shop around to get the cheapest deal that suits your needs the most. You will usually be required to select where you want to pick up the portable WiFi from.
- Most people will choose to pick it up at the airport, but you can also arrange for it to be sent to your accommodation.
- At the end of your trip, you will most likely ship the router back to the Japan pocket WiFi provider from the airport using the returning envelope provided. But again, check the terms and conditions of the deal you signed up for.
- If you find yourself in a situation where you run out of data, you can also purchase another Japan Travel SIM from Bic Camera, which has numerous branches nationwide.
Important: Ensure that your smartphone is unlocked to allow the SIM card to function properly.
What is a Pocket WiFi?
A Pocket WiFi or Portable WiFi is a pocket-sized mobile router that allows you to access an internet connection on the go. Most portable WiFi devices use 4G signals from network providers to enable the connection. The advantage of using a Pocket WiFi is that it can connect to multiple devices and typically provides more data. If you plan to travel in a group or have multiple devices that require an internet connection, a Pocket WiFi may be a better option.
However, because a Pocket WiFi can only be rented, rather than purchased, in most cases, it needs to be picked up and returned while you are in Japan. This may cause inconvenience and result in wasted valuable travel time during the rental process.
For more information about Japan pocket WiFi, including the pros and cons and a detailed explanation of our recommended Japan pocket WiFi providers, refer to our Japan pocket WiFi article!
Recommended Japan Pocket WiFi Providers
- Sakura Mobile: Suitable for longer travel periods or last-minute bookings.
- Japan Wireless: Suitable for shorter travel periods.
- NINJA WiFi: Suitable for a travel period of 1 week or less.
- Japan WiFi Rental: Suitable for those with a strict budget.
- Mobal: Suitable for newly arrived residents and expats.
The Best Japan Pocket WiFi Providers for Short-Term Travelers
Japan Wireless, and NINJA WiFi are Japan’s top three Pocket WiFi providers. Each provider’s pricing differs slightly because the level of services they provide isn’t the same. The best Japan Pocket WiFi company for you depends on your travel type and internet usage pattern. So, refer to the table below to find the Japan Pocket WiFi provider you should use.
Our favorite Japan pocket WiFi provider is Sakura Mobile. The company uses NTT DoCoMo’s network, the best network in Japan. This means the greatest coverage and the fastest speed. Their pick-up counter at the airport also has long opening hours. The one at Haneda Airport is only closed from 1 am to 4 am, accommodating early and late arrival passengers.
| Japan Pocket WiFi Provider | Network Used | FUP (Fair Usage Policy) | Daily Cost for a 28-Day Rental | Number of Devices | Can I Return the Pocket WiFi at the Airport? | Need to Pay for the Postage to Return the Device? |
| Sakura Mobile (click for more info) | NTT DoCoMo | 3GB, the speed may slow down after 3GB is used. | 632 Yen/Day | 15 | Yes | No |
| Japan Wireless (click for more info) | Softbank | Not provided, but confirmed that the speed will be limited if excessive data is used. | ☛ Business WiFi Plan: 577 Yen/Day ☛ Premium WiFi Plan (for data-heavy users): 615 Yen/Day | 10 | No | No |
| NINJA WiFi (click for more info) | Softbank | Depending on the plan you choose | ☛ 3GB High Speed: 770 Yen/Day ☛ 5GB High Speed: 1,100 Yen/Day ☛ 10GB High Speed: 1,320 Yen/Day ☛ Unlimited High Speed: 1,980 Yen/Day | 10 | Yes | No |
- Note that after the day’s FUP (Fair Usage Policy) threshold is met, you can still connect your devices to the internet, but at a low speed.
- While Japan Wireless’s website states that the maximum download speed is 187Mbps, the actual speed is greatly affected by several factors. In Tokyo, the company has confirmed that the typical download speed for the premium plan is approximately between 20 and 40 Mbps.
Using a Japan Tourist SIM Card
SIM cards, on the other hand, can be purchased before your arrival. It is the best option if you need a Japanese phone number while you are in Japan or if your phone isn’t compatible with an eSIM.
After the initial APN configuration, you can use your phone just like you would at home. Depending on the SIM card providers, you might be able to complete all required APN configurations before you reach Japan. And if that isn’t an option for you, you can always utilize the internet at the airport and/or on bullet trains or limited express trains to complete the setup process.

The Best SIM Card in Japan for Tourists
Similar to Pocket WiFi, you can purchase a SIM Card with limited or unlimited data. But note that unlimited data is subject to the Fair Usage Policy (FUP). If the service provider determines that your usage is excessive on a particular day, your internet speed will be downgraded for a few days.
Our favorite is Japan Wireless (assuming you aren’t a data-heavy user). The company’s product has the best CP value. But if you plan to head into the wild, it is worthwhile to purchase Sakura Moile‘s SIM card to access DoCoMo’s network. It is the best network in Japan. This means the greatest coverage and the fastest speed. Additionally, Sakura Mobile’s customer service is exceptional. You will usually receive a response within 10 to 20 minutes, even on a weekend.

Using a Japan Travel eSIM
An eSIM is an industry-standard digital SIM that enables you to activate a mobile data plan from your service provider without the need for a physical SIM. You can install eight or more eSIMs on an iPhone or other compatible devices and use two phone numbers at the same time!
The best thing about an eSIM card is that your SIM card won’t get lost in the mail, and you don’t need to wait for it to be delivered. If you run out of data, you can simply purchase another eSIM in Japan!
But as it is a new product, most eSIM cards currently only support newer phone models.
