1. Overview of SIM Card Options for Short-term Stays in Japan
For foreigners visiting Japan for a short-term stay, having a reliable mobile network is essential to stay connected, navigate, and communicate with ease. Japan offers a variety of SIM card options specifically designed for short-term visitors, commonly referred to as “Japan short-term SIM”. These SIM cards cater to tourists and business travelers, providing affordable and convenient plans tailored to their needs.
Most short-term SIM cards in Japan focus on data services rather than voice calls, as many travelers prefer using online communication apps like WhatsApp, LINE, and Skype. However, some options also include voice and SMS capabilities for an additional cost. The primary features to consider include data limits, duration of validity, and ease of purchase.
Prepaid SIM Cards
Prepaid SIM cards are the most popular choice for short-term stays. These cards usually offer fixed data packages, such as 1 GB, 5 GB, or unlimited data plans. Prices range from around ¥3,000 to ¥7,000 ($20–$50) for a 7- to 30-day period. Major providers include:
- b-mobile: Offers affordable data-only plans starting at ¥1,980 ($14) for 7 days with 1 GB of data.
- Japan Travel SIM by IIJmio: Provides flexible options, such as ¥2,980 ($20) for 2 GB of data valid for 14 days.
- U-Mobile: Known for its unlimited data plan at ¥4,500 ($32) for 15 days.
Airport SIM Card Kiosks
Many airports in Japan, including Narita, Haneda, and Kansai, have SIM card kiosks where visitors can purchase “Japan short-term SIM” cards upon arrival. These kiosks offer convenience but may charge slightly higher prices compared to online or in-city purchases. Expect to pay ¥3,500–¥5,000 ($25–$35) for a 7- to 14-day data plan.
Online SIM Card Purchase
Ordering SIM cards online before arriving in Japan is another convenient option. Websites like Sakura Mobile and Mobal allow you to select and prepay for a SIM card, which can be delivered to your accommodation or picked up at the airport. This method often provides better deals and ensures you are connected as soon as you arrive.
Pocket Wi-Fi as an Alternative
For foreigners traveling in groups or requiring multiple device connections, pocket Wi-Fi is an alternative worth considering. While not a SIM card, pocket Wi-Fi devices provide unlimited data and can connect multiple devices simultaneously. Prices start at around ¥500 ($3.50) per day and can be rented from major providers like Ninja Wi-Fi or Global Advanced Communications.
By understanding these options, visitors can select the most suitable SIM card plan for their short-term stay in Japan, ensuring a seamless and connected travel experience.
2. Key Factors to Consider When Choosing a SIM Card
For foreigners planning a short-term stay in Japan, selecting the right “Japan short-term SIM” is crucial for a seamless and connected experience. Several factors should be taken into account to ensure the chosen SIM card meets your specific needs and budget. Below, we break down the key considerations for making an informed decision.
1. Data Allowance
The amount of data provided by a SIM card is one of the most critical factors to consider. If you primarily use your smartphone for navigation, social media, and messaging, a SIM card offering 2–5 GB may suffice. For heavy users who stream videos, attend online meetings, or require constant connectivity, unlimited data plans are a better choice. For example:
- b-mobile: Offers 1 GB for ¥1,980 ($14) or larger data plans up to 10 GB for ¥5,000 ($35).
- U-Mobile: Unlimited data plans start at ¥4,500 ($32) for a 15-day duration.
2. Duration of Stay
Short-term SIM cards in Japan typically have validity periods ranging from 7 to 30 days. It’s essential to match the SIM card’s duration to your travel plans. Some providers, like Sakura Mobile, allow you to extend the validity for an additional fee. If your stay exceeds the SIM card’s validity, you may need to purchase a second card or opt for a more flexible plan.
3. Type of Service: Data-Only vs. Voice and SMS
Most “Japan short-term SIM” cards are data-only, catering to the needs of foreigners who rely on internet-based communication apps such as LINE, WhatsApp, and Skype. However, if you anticipate the need for local phone calls or SMS, choose a SIM card that includes voice services. For instance:
- IIJmio: Offers optional voice call services for an additional ¥1,000 ($7) per month.
- Sakura Mobile: Includes both data and voice plans starting at ¥3,500 ($25).
4. Network Coverage
Reliable network coverage is essential for uninterrupted connectivity, especially in rural or remote areas. Major carriers like NTT Docomo, SoftBank, and AU provide excellent nationwide coverage. Many short-term SIM providers operate on these networks, ensuring good service quality. Confirm that the provider you choose utilizes one of these networks to avoid connectivity issues.
5. Ease of Purchase and Activation
For convenience, consider how and where you can purchase and activate your SIM card. Some SIM cards are available for purchase online, at airport kiosks, or in electronics stores like Bic Camera and Yodobashi Camera. Online purchases often provide better deals, while airport kiosks offer immediate activation upon arrival. Activation processes are usually straightforward, involving a QR code scan or a step-by-step guide provided by the provider.
6. Budget
Your budget is another critical factor. Prices for short-term SIM cards vary depending on data limits, duration, and included features. Expect to pay between ¥2,000–¥7,000 ($14–$50) for most plans. Unlimited data options and voice-capable SIM cards generally cost more but offer greater convenience.
7. Device Compatibility
Ensure that your smartphone is unlocked and compatible with Japanese SIM cards. Most modern devices support Japan’s LTE bands, but it’s advisable to confirm compatibility with your chosen provider before purchasing. Additionally, if your device requires a specific SIM card size (nano, micro, or standard), check that the provider offers the correct format.
By carefully evaluating these factors, foreigners can confidently select the best “Japan short-term SIM” to suit their travel requirements, ensuring a hassle-free and connected experience throughout their stay in Japan.

Whether you’re a tourist or a business traveler, these practical tips will help you save data, stay connected, and avoid potential issues during your stay in Japan. Here’s how to ensure you get the best value out of your SIM card.
1. Monitor Your Data Usage
Data allowances on “Japan short-term SIM” cards can vary, so keeping track of your usage is essential. Many providers offer apps or online dashboards to help you monitor your remaining data. Alternatively, use your smartphone’s built-in data tracking features. For example:

If you’re approaching your data limit, consider purchasing additional data through your SIM card provider. For instance, b-mobile offers top-up options starting at ¥1,000 ($7) for 1 GB.
2. Use Wi-Fi Whenever Possible
To conserve mobile data, connect to Wi-Fi networks whenever available. Many hotels, cafes, restaurants, and public spaces in Japan provide free Wi-Fi. Use apps like “Japan Connected-Free Wi-Fi” to locate nearby hotspots. Pocket Wi-Fi devices are also a great alternative, especially for groups or heavy users, starting at ¥500 ($3.50) per day.
3. Optimize App Settings
Adjusting your app settings can significantly reduce data consumption. Here’s how:
- Disable autoplay for videos on social media platforms like Instagram, Facebook, and Twitter.
- Download maps for offline use in navigation apps like Google Maps or Maps.me.
- Limit background data usage by going to your device’s settings and disabling background data for specific apps.
By managing app settings, you can ensure your data lasts longer without compromising functionality.
4. Use Messaging Apps for Communication
Since most “Japan short-term SIM” cards are data-only, use messaging apps like WhatsApp, LINE, or Skype for calls and texts. These apps are highly popular in Japan and offer free or low-cost international communication. Make sure your contacts also use these platforms for seamless communication.
5. Know Your Provider’s Support Channels
If you experience connectivity issues or need assistance, many providers offer English-speaking customer support for “foreigners”. Save the provider’s contact information, including email and phone numbers, for quick reference. For example:

- IIJmio: Access their support portal or FAQ section online.
6. Be Aware of Network Coverage
While most SIM cards operate on reliable networks like NTT Docomo or SoftBank, rural or remote areas may have limited coverage. Plan ahead if you’re visiting off-the-beaten-path destinations by downloading offline resources or confirming coverage with your provider.
7. Plan for Emergencies
In case of emergencies, ensure you have a way to contact local services. Some data plans offer access to emergency numbers without charge, even if your data runs out. Alternatively, consider a pocket Wi-Fi device for backup connectivity.
8. Top-Up Options
If you run out of data, most providers allow easy top-ups. This can be done online, at convenience stores, or through the provider’s app. For example, Japan Travel SIM by IIJmio offers additional 1 GB data packages for ¥1,500 ($10), ensuring you can stay connected as needed.
