SIM Card vs PocketWiFi in Japan
Explore new streets with your smartphone in hand. Navigate to your destination without getting lost using map apps. Check train schedules in real-time. Converse even if you don't understand Japanese by using translation apps.
For such convenient travel, internet connection is an essential item for modern travelers. Especially in Japan, public WiFi spots are still not as widespread as in other countries.
But how should you connect to the internet?
There are two popular options for travelers: "SIM cards" and "Pocket WiFi." Both have their pros and cons, and the optimal choice varies depending on your travel style.
Are you prioritizing cost? Using it with multiple people? Battery life? Wide coverage area?
This article thoroughly compares the options to make your Japan trip more comfortable. Let's find the optimal connection method for your travel style.
Benefits and Drawbacks of PocketWiFi in Japan
Walking through Japanese streets and reaching your destination without getting lost using Google Maps. Smoothly changing trains with just your smartphone. Sharing travel memories on social media in real-time.
This chapter introduces the appeal of Pocket WiFi that makes such convenient travel possible. From the convenience of connecting multiple devices simultaneously to high-speed communication covering all of Japan, you'll understand everything about Pocket WiFi that will make your trip significantly more comfortable.
We'll explain the key points for choosing WiFi in an easy-to-understand way, even for first-time visitors to Japan. With this information, you can enjoy your Japan trip to the fullest without worrying about internet connectivity.
Benefits of Pocket WiFi
- 1.Multiple device connections possible
- 2.Large-capacity and unlimited data plans
- 3.Convenience of portability
Multiple Device Connections Possible
The biggest appeal of Pocket WiFi is that it can connect multiple devices to the internet with just one unit. This feature is especially valuable for group or family travel.
Typical Pocket WiFi can connect 5-10 devices simultaneously, allowing everyone to use their own smartphones or tablets. This results in significant savings since each person doesn't need to purchase a SIM card.
For example, while your partner is uploading photos to Instagram, you can look up directions to the next tourist spot. Children can enjoy games or videos at the same time. Everyone has the freedom to use the internet at their own pace.
Switching between devices is also easy. Once set up, devices connect automatically when within WiFi range (typically 10-15 meters).
During Japan travel, you'll likely need to use various apps simultaneously on multiple devices, such as map apps, translation apps, and train schedules. With Pocket WiFi, the entire group can share a smooth online experience.
Large-Capacity and Unlimited Data Plans
During Japan travel, smartphone data usage can be surprisingly high. Constantly checking maps of unfamiliar streets, taking and posting photos of beautiful scenery and delicious food.
With Pocket WiFi, you can enjoy your trip without worrying about data usage.
Many rental services offer plans with more than 3GB per day or completely unlimited plans. What does this mean?
First, you can use navigation apps like Google Maps or Yahoo! Transit all day long. No need to worry about getting lost. Even Japan's complex train transfers are supported by apps in real-time.
Furthermore, you can enjoy posting to social media as much as you like. There are no additional charges for uploading high-quality photos or videos. Video calls with family and friends are also possible.
Japan's high-speed communication network is world-class. To fully benefit from this, sufficient data capacity is essential.
The peace of mind of not having to worry about data limits during your trip will significantly improve the quality of your travel experience.
Convenience of Portability
You want to stay connected to the internet throughout your Japan trip, but keep your luggage light. Pocket WiFi fulfills this wish. For travelers, the portability of this small device is a major attraction.
The latest Pocket WiFi devices typically weigh only 100-200 grams and are roughly the same size as smartphones. They fit into pockets or small spaces in bags, making them easy to carry without bulkiness. Waterproof models are increasing, so you don't have to worry about sudden rain.
Moreover, pocket WiFi significantly reduces battery consumption compared to using a SIM card in your smartphone. Since data communication consumes a lot of battery, this difference is important for travelers sightseeing all day.
Also, you can simply take it out with your smartphone during security checks, making it easy to pass through airport security. Though small, it will be a reliable companion that smoothly supports your Japan trip.
Drawbacks of Pocket WiFi
- 1.Need to carry an additional device
- 2.Slightly higher cost
- 3.Battery life limitations
Need to Carry an Additional Device
The first drawback to consider when choosing Pocket WiFi is the need to carry an additional device. In addition to your smartphone, you must manage another device, albeit a small one.
Managing valuables becomes more complicated during travel. There's a risk of accidentally dropping it from your pocket or forgetting it in restaurants or taxis. Attention can be especially scattered when busy with sightseeing.
Charging is also a double effort. You need to charge not only your smartphone but also the WiFi router every night. Some ryokans or older accommodations may not have enough outlets.
It's not uncommon to find yourself searching for it in your bag. Small black devices can be hard to find when they sink to the bottom of your bag.
As a countermeasure, it's recommended to prepare a dedicated pouch or always store it in a fixed location. Also, saving the rental company's contact information separately provides peace of mind. This makes it easier to respond in case of loss.
Slightly Higher Cost
When considering your travel budget, Pocket WiFi rental fees can be a significant expense. For solo travelers, this cost aspect can be a disadvantage.
Pocket WiFi rental in Japan typically costs between 800 and 1,500 yen per day.
This may be acceptable for short trips, but the total amount grows for stays longer than two weeks. On the other hand, SIM cards often have a fixed cost of 2,000 to 5,000 yen.
For long-term visitors, this price difference has a significant impact on the travel budget. Especially when used alone, the cost-effectiveness should be carefully considered.
Even though the daily expense may be small, it becomes a substantial amount by the time you return home.
Also, higher-speed plans tend to be more expensive. Unlimited plans are even more costly.
To reduce costs, take advantage of online pre-booking discounts or long-term rental discounts. For group travel, sharing one device significantly reduces the cost per person. If you prioritize budget, it's wise to choose based on your travel duration and number of people.
Battery Life Limitations
When it comes to internet connection during travel in Japan, the battery life of pocket WiFi is an important consideration. While catalogs may state 8-12 hours of usage, in actual use conditions, it's often shorter.
If you're sightseeing from morning till night, battery depletion becomes a concern. It would be troublesome if the battery runs out while you're having dinner at 10 PM after starting a temple tour in Kyoto at 9 AM. If the map app becomes unavailable, foreign tourists face a higher risk of getting lost.
The more devices connected, the faster the battery consumption. Sharing with family or groups is convenient, but power consumption increases accordingly. Also, during Japan's hot summer, devices can heat up, reducing battery efficiency.
Securing charging time is also a challenge. You might need to create charging time at cafes during sightseeing.
As a countermeasure, bringing a small mobile battery provides peace of mind. Also, develop the habit of turning off WiFi when not in use. When renting, choosing newer models tends to result in better battery life.
About eSIM in Japan
The era has arrived where you can use Japan's high-speed communication by simply scanning a QR code, without the hassle of replacing physical SIM cards.
This is called "eSIM" - the next-generation SIM technology built into smartphones.
The convenience of purchasing online before departure and connecting to the internet from the moment you arrive in Japan is attracting attention from travelers worldwide.
No complicated procedures or waiting time at airport counters required. It can be set up easily with just your smartphone.
Benefits of eSIM
- 1.No need to exchange physical SIM cards
- 2.Pre-purchase and immediate activation
- 3.Dual SIM functionality
No Need to Exchange Physical SIM Cards
For internet connection during Japan travel, the most attractive feature of eSIM is that no physical SIM card is required. The traditional method involved opening your device with a small pin, removing your home country SIM, and inserting a Japanese SIM.
With eSIM, there's no need to open your smartphone, and zero risk of losing the small SIM card.
This brings significant peace of mind, especially in a travel environment. There's no risk of dropping your SIM in crowded airport areas.
Setup is very simple. Just scan a QR code. Or simply download the profile from a dedicated app. No need to carry SIM pins or replacement trays.
Also, returning to your original settings when going home is easy. Without the hassle of exchanging physical cards again, you can switch with just a few taps in the settings screen.
It's expected that this technology will become more widespread and standard in the future.
Being freed from the constraints of physical SIM cards during your stay in Japan will make your travel experience smoother and more stress-free. Even those who aren't tech-savvy will find it surprisingly easy to use.
Pre-purchase and Immediate Activation
A major attraction of eSIM is that you can prepare your internet connection before departing for Japan.
If you purchase an eSIM online during the planning stage of your trip, you can connect to Japan's high-speed communication network the moment you get off the plane.
The convenience of being able to immediately check how to get to the nearest station with Google Maps or use translation apps after arrival is immeasurable. It also saves time waiting at airport counters.
No need to stand in long lines when you're tired anymore.
Being able to connect to the internet immediately upon arrival in Japan makes the start of your trip smoother.
This is especially reassuring when arriving late at night or if you're concerned about language barriers. You can also feel secure about finding your way to your hotel.
You can complete the setup before departure, so when you arrive, you just need to turn on the communication settings. With just a WiFi environment, you can finish setup at home or at your hotel before departure.
Also, many plans allow you to specify the start date according to your travel schedule, so unnecessary fees won't occur. For planners, this flexibility is a significant benefit.
To maximize your valuable time in Japan, eSIM preparation before departure is recommended.
Dual SIM Functionality
One of the attractive features of eSIM is that you can use Japanese data communication while maintaining your home country phone number. Most of the latest smartphones support this dual SIM function.
Being able to use your home country's physical SIM and eSIM simultaneously means you won't miss important communications.
You can still receive urgent messages from friends and family, notifications from banks, and SMS for two-factor authentication. This is especially valuable for long-term travelers or business travelers.
Being able to continue using your usual phone number enhances security.
This is because various services and authentication systems linked to your home country phone number can be used without interruption. Online banking can also be used with peace of mind.
However, roaming charges may apply to your home country's services, so it's wise to use the eSIM for data communication and your home country's SIM for calls and SMS. You can easily switch in the settings screen.
This flexibility makes your stay in Japan more comfortable.
You can handle accommodation changes or schedule adjustments while maintaining contacts in both countries. For next-generation travelers, the dual SIM function can be said to be an essential feature.
Drawbacks of eSIM
- 1.Device compatibility limitations
- 2.Complexity of initial setup
- 3.Limited support system
Device Compatibility Limitations
While eSIM is a convenient technology, not all travelers can use it. The first thing to check when considering this new connection method is whether your smartphone is compatible with eSIM.
The latest iPhones (XS and later), Google Pixels (3 and later), and Samsung Galaxy S20 and later flagship models are compatible, but many mid-range and low-price smartphones are still not compatible.
Especially models from before 2019 are often not compatible.
If you fail to check whether your device is compatible with eSIM before traveling, you may experience great disappointment after arriving in Japan. This check is especially important for travelers visiting multiple countries.
Check your device's model number on the manufacturer's website or in the settings menu.
Even if your device is compatible, it may be locked by certain countries or carriers. You may need to check with your contract carrier.
At this point, not everyone in a travel group may be able to use eSIM.
For family travel, some members may need to choose traditional SIM cards or Pocket WiFi. As it takes time for technology to spread, it's wise to consider multiple connection options for the time being.
Complexity of Initial Setup
Using eSIM requires more setup steps than traditional SIM cards. For travelers who aren't tech-savvy, this initial setup can be a hurdle.
First, a WiFi environment is essential for downloading eSIM profiles. If your hotel WiFi is unstable or there's a password entry error, setup may fail midway. Also, scanning QR codes or installing dedicated apps involves more steps than physically inserting a traditional SIM card.
Setting screens are often only available in English, creating an additional barrier for travelers from non-English speaking countries. Specialized terms like "mobile data," "APN settings," and "network selection" can cause confusion. Sometimes a restart is required.
Furthermore, setup procedures differ by provider, so general online guides may not apply. You need to strictly follow the instructions from the eSIM provider you purchased from.
As a countermeasure, it's recommended to set up in advance in your home WiFi environment with plenty of time. Also, saving screenshots of the setup method can be helpful.
Preparing in a calm environment before arriving in Japan will make the start of your trip smoother than rushing to set up after arrival.
Limited Support System
Many eSIM services are provided by online-only providers, and the lack of physical support locations can be a disadvantage. This is especially apparent when technical problems occur.
If you experience connection issues during your stay in Japan, resolving them basically depends on self-resolution or online support.
There's no reassurance of being able to go to a physical store for direct consultation. Email or chat exchanges may take time due to time differences.
Language barriers are also a significant challenge.
Support is limited in languages other than Japanese and English, and you may not be able to receive support in your native language. Conversations involving technical terms are particularly difficult when languages differ.
Also, some eSIM providers don't offer 24-hour support, so you may not get immediate assistance for issues that occur at night or on holidays.
This weakness in the support system becomes more noticeable when you're in a hurry.
To reduce this risk, it's important to choose providers with good reputations. Check reviews before use and select services with high ratings for support response.
Also, learning basic troubleshooting methods (restart, reset settings, etc.) in advance provides peace of mind. Knowing how to respond when problems occur will make your stay in Japan more comfortable.
Benefits and Drawbacks of SIM Cards in Japan
For those planning a trip to Japan, we'd like to introduce the SIM card situation in Japan.
Japan boasts world-class communication infrastructure and offers a variety of convenient SIM card options for travelers. However, you may be confused by systems and procedures that differ from your home country.
Understanding Japan's SIM card situation in advance enables smooth internet connection immediately after arrival.
We'll explain how to purchase at airports, fee structure characteristics, how to choose data capacity, and the optimal options for your travel budget and purpose.
This chapter comprehensively delivers information from basic knowledge about Japanese SIM cards that foreign travelers should know to practical advice to make your stay in Japan more comfortable.
You'll be able to seamlessly share memories on social media, from Tokyo's cityscapes to Kyoto's ancient temples.
Benefits
- 1.High-speed and stable communication quality
- 2.Diverse options
- 3.Ease of purchase
High-Speed and Stable Communication Quality
When traveling to Japan, you'll be surprised by the high quality of internet connection. Japan's communication network is world-class.
Your smartphone works smoothly everywhere, so you can visit tourist spots without getting lost using Google Maps.
Stable communication environments are established not only in major cities like Tokyo and Osaka but also in regional tourist areas.
You'll be able to smoothly post to social media in most places, except for some mountainous areas and underground metros.
This high-quality communication environment is Japan's strength.
Many foreign travelers feel that "the communication speed is faster than in my home country." Video streaming is also smooth, allowing you to comfortably spend small pockets of free time during your trip.
During your stay in Japan, you rarely need to worry about communication speed or connection stability. Just remember that communication may temporarily slow down during fireworks festivals or large events where people congregate.
Diverse Options
In Japan, a variety of SIM cards are sold to meet different needs. Anyone from short-term travelers to long-term residents can find options that suit them.
For travelers, there are limited-period plans from 1 to 30 days.
Data capacity also varies widely from small-capacity 1GB plans to unlimited plans, allowing you to choose based on budget and purpose.
Small-capacity plans are recommended for just using social media, while large-capacity plans are better if you'll watch lots of videos.
Comparing prices and service contents before purchasing helps avoid unnecessary expenses.
For example, "Japan Welcome SIM" and "IIJmio Travel SIM" are popular plans among tourists. Some services include English support, providing reassurance when you struggle with settings.
The Japanese SIM card market is actively competitive, so new cost-effective plans are constantly emerging.
It's good to check each company's latest plans online before arrival or consult at the airport information counter. Enjoy your comfortable Japan trip with a SIM card that matches your stay style.
Ease of Purchase
You can get a SIM card as soon as you arrive in Japan. This provides great reassurance for many travelers.
Narita Airport and Haneda Airport have multiple counters selling SIM cards for foreigners.
Staff can assist in English, so there's no language worry. Besides airports, you can also purchase them at convenience stores around town or large electronics stores like BIC Camera.
Convenience stores operate 24 hours, so you can obtain one even if you arrive late at night.
Services where you can pick up a SIM card at the airport without waiting time if you reserve online in advance are also popular.
Being able to save waiting time after a long flight is an appreciated point. Some hotels also prepare SIM cards for their guests.
Purchased SIM cards can be used immediately. In most cases, setup is completed by following the simple instructions on the package.
This allows even those who aren't tech-savvy to use them with confidence. Secure a comfortable internet environment from the first step of your Japan trip.
Drawbacks
- 1.Relatively high fees
- 2.Language barrier
- 3.Strictness of identity verification
Relatively High Fees
Japanese SIM cards are convenient, but it's important to note that prices tend to be high. Plans for short-term travelers are especially expensive.
Compared to many countries worldwide, Japan's data communication fees tend to be high. For example, a 7-day traveler plan typically costs between 1,500 and 3,000 yen.
This is quite expensive compared to other Asian countries. Many plans also have modest data capacity, requiring attention.
Unlimited plans do exist, but they are either very expensive or mostly impose speed limits after exceeding a certain amount.
In Japan, you need to be mindful of data usage. Even just using map apps and uploading photos can consume more data than expected.
We recommend comparing your home country carrier's international roaming service and fees before traveling.
For short trips, international roaming may sometimes be more cost-effective. Also, using free WiFi available at many hotels, stations, and cafes is a wise choice.
Language Barrier
When using Japanese SIM card services, you may face language barriers. This is a challenge many foreign travelers experience.
SIM card packages and instructions are often written only in Japanese, making it difficult to understand setup methods.
Some products do support English, but not all. Be especially careful if purchasing from small shops around town. Purchase from major electronics stores or airport sales counters, which are more likely to support English.
If you encounter setup troubles, customer support is generally only available in Japanese. Phone inquiries are even more difficult.
Some traveler-oriented SIM cards include English support, but support hours may be limited or only available via email.
To avoid language issues, it's reassuring to research SIM card setup methods before departure.
Another approach is to ask hotel staff for help. Japanese people are kind, so if you communicate that you're having trouble, they'll often assist you. Preparation in advance is an important point.
Strictness of Identity Verification
In Japan, identity verification for SIM card contracts is very strict. This is due to Japanese law and is part of security measures.
Prepaid SIMs for short-stay tourists are relatively easy to purchase, but passport presentation is still required. Some stores may take a copy. On the other hand, for long-term residents contracting SIMs with voice calls, requirements are stricter.
Not only passports but also residence cards and proof of Japanese address are required.
For regular contracts with Japanese mobile companies, multiple documents such as foreign registration certificates or residence cards are needed, making the procedure complicated.
For short-term travelers, it's recommended to avoid these complex procedures and choose prepaid SIMs with data communication only.
Be aware that you may not be able to sign a contract on the spot if the necessary documents are not available.
Recently, procedures have improved, with simplification for foreigners progressing at major airports and tourist area stores.
Still, procedures are complex compared to other countries. Start the purchase procedure with plenty of time or apply online in advance for a smooth start to usage.

Physical SIM Cards for Those Wanting to Keep Costs Down
Physical SIM cards are the most common internet connection method. In Japan, they can be purchased at many locations including airports, convenience stores, and electronics stores.
The greatest attraction of physical SIMs is their price and variety of choices.
You can choose from various plans based on your travel period and needed data amount.
Options range from 3-day short stays to 30-day long plans, available for about 1,000-4,000 yen. Data capacity also varies widely from small-capacity 1GB plans to large-capacity plans over 50GB.
Physical SIMs are especially recommended for travelers wanting to keep their budget down or those prioritizing cost efficiency.
While they require slightly more effort than eSIMs, the lower price is a significant advantage. Another notable point is that they can be used with older smartphone models.
They're a reliable option for those without the latest models.
When using them, check if your smartphone is SIM-unlocked.
