Tokyo SIM card: Best travel data options and where to buy

When traveling to Tokyo, having reliable internet access is essential. Whether you need maps, translation apps, or want to stay in touch with family and friends, choosing the right Tokyo SIM card can make your trip smoother and more enjoyable. This guide will help you understand where to buy a SIM card in Tokyo, how much it costs, and which options are best for tourists in 2025.

Where can you buy a SIM card in Tokyo?

Getting a Tokyo SIM card is straightforward with many buying points suited to different traveler needs. Whether you want immediate connectivity upon arrival or prefer researching options in the city, there are convenient solutions. This flexibility makes it easy to stay connected throughout your visit.

Tokyo airports (Narita, Haneda)

Tokyo’s two major international airports, Narita and Haneda, offer quick and easy SIM card purchases upon landing. Both airports have multiple kiosks and vending machines selling prepaid SIM cards tailored for tourists. These SIMs typically include ample data allowances, local call minutes, and text messaging capabilities.

Buying at the airport guarantees instant mobile service, so you can start using maps, translation apps, or stay in touch with family right away. Keep in mind, prices here tend to be slightly higher compared to city stores because of the convenience factor. Still, many travelers find the ease and immediacy well worth it.

Bic Camera, Yodobashi Camera & convenience stores

If you want a wider selection and sometimes better deals, consider visiting large electronics retailers such as Bic Camera and Yodobashi Camera. These stores are located in major shopping districts across Tokyo, like Shinjuku and Akihabara, and stock SIM cards from different providers with varied data packages and durations. Staff at these stores can often assist with choosing the right SIM and sometimes even help with activation.

In addition to electronics shops, convenience stores like Lawson, FamilyMart, and 7-Eleven also sell prepaid SIM cards. While the selection might be smaller, convenience stores have the advantage of widespread locations and extended hours, making them ideal for last-minute purchases or emergency top-ups during your trip.

Order online before your trip

Ordering a SIM card online before traveling to Tokyo is gaining popularity, especially among tech-savvy tourists. This option allows you to buy either a physical SIM card or an eSIM from providers like BitJoy or Holafly. These cards can be shipped to your home or downloaded digitally (for eSIMs), allowing you to activate your service immediately upon arrival without waiting in lines.

Pre-ordering your SIM card gives you peace of mind, knowing your mobile data is ready when you land. Online options also often include competitive prices and flexible plans tailored to your travel duration, making it a smart choice for frequent travelers or those who want to avoid airport crowds.

How much does a SIM card in Tokyo cost?

When planning your budget for a Tokyo SIM card, expect prices to vary based on data limits and validity periods. Prices reflect the quality of service, data speed, and provider reputation. It’s essential to balance cost and your expected usage.

Price ranges for short-term tourist SIMs

Tourist SIM cards in Tokyo typically range from ¥2,000 to ¥4,500. The lower end usually includes 1-3GB of data valid for 7 days, while mid-range options offer 5-10GB for 15 days. Unlimited data plans start around ¥4,000 and extend up to 30 days. Physical SIMs bought at airports or stores tend to be slightly pricier than eSIM options ordered online.

Keep in mind that some providers include bonus features such as free calls within Japan or hotspot tethering, which can add value. Make sure to compare data limits, speeds, and activation ease before buying. This ensures you get the best deal suited to your itinerary and digital habits.

Tips on choosing the right data package

Selecting the perfect data plan depends on your travel style and tech use. If you’re mostly browsing maps and checking messages, a smaller data package around 3-5GB should suffice for a week. Heavy users who stream videos or upload frequently may want 10GB or unlimited options for uninterrupted access.

Also, check the validity period of the SIM card carefully. Some plans expire quickly, which might not match your trip duration. Finally, confirm whether your device supports the SIM type (physical or eSIM) and network frequencies. Choosing wisely helps avoid extra costs or service disruptions during your stay.

Pocket Wi-Fi vs. SIM card in Tokyo: Which one to choose?

When visiting Tokyo, one of the most common questions travelers have is whether to rent a pocket Wi-Fi or purchase a SIM card. Both options allow internet access throughout your trip, but the better choice depends on your travel habits, group size, and device needs. Here's a detailed breakdown to help you decide.

Pros and cons for different travel needs

SIM Card

A SIM card is an excellent option for solo travelers or those with lighter data needs.

• Pros:

• Very convenient—just insert and go.

• No need to carry or charge an extra device.

• Usually cheaper if you're traveling alone.

• Many providers (e.g., BitJoy, Holafly) support eSIM, allowing instant setup.

• Cons:

• Often comes with a data cap.

• Tethering may or may not be allowed—check with the provider.

• SIM size and settings may vary by phone model.

Pocket Wi-Fi

This is a good solution for groups or travelers who plan to stay connected on multiple devices.

• Pros:

• Can connect several devices simultaneously (phones, tablets, laptops).

• Many plans offer unlimited data, great for video calls or streaming.

• No concern about SIM size or phone compatibility.

• Cons:

• Needs to be charged regularly.

• Must be picked up and returned, unless delivered to your hotel or airport.

• Generally costs more than a SIM for solo use.

If you're traveling solo and don’t need large amounts of data, a SIM card is simple and affordable. If you're traveling with others or need lots of bandwidth, pocket Wi-Fi is worth the extra cost.

Do SIM cards in Tokyo support tethering and Japanese numbers?

Many travelers wonder if a tourist SIM allows hotspot sharing or comes with a local number. Here’s what you need to know before buying.

Using a hotspot with a tourist SIM

Most tourist SIM cards in Tokyo do support tethering, letting you share your mobile data with laptops or tablets. Providers like BitJoy and Mobal confirm that hotspot usage is allowed.

However, not all SIMs allow this—especially low-cost or limited-data plans. Always check the plan details to make sure hotspot functionality is included. Also, confirm that your phone supports tethering.

Getting a Japanese phone number – is it possible?

Tourist SIM cards are usually data-only, so they don't include a Japanese phone number. This is fine for using Google Maps, browsing, and messaging apps.

If you need a Japanese number to make local calls or receive SMS, look for special plans like Mobal's voice + data SIMs. These come with a number but may require extra paperwork or identification.

FAQs about buying a SIM card in Tokyo

Buying a SIM card in Tokyo is easier than ever, especially with the growing availability of tourist-friendly plans and support in English. Below are answers to some common questions to help you prepare.

How much data do I need for a trip to Japan?

Light users who mainly use maps and email will need around 1 to 2 GB of data per week. If you plan to browse the web and use social media regularly, expect to need 3 to 5 GB. For streaming videos or working remotely, 10 GB or more is recommended each week.

Can I activate my SIM easily as a tourist?

Yes, activation is usually straightforward. eSIMs from providers like BitJoy or Holafly require you to scan a QR code for instant setup. For physical SIMs, just insert the card into your phone and follow the English instructions provided. If you need help, staff at the airport or electronics stores like Bic Camera are available to assist.

Should I use eSIM instead of physical SIM?

If your phone supports it, an eSIM is the more convenient option. You can activate it instantly and switch between plans easily without removing a physical card. For travelers with older phones or those who prefer a physical backup, a traditional SIM still works well. In most cases, eSIMs offer more flexibility and are better suited to modern travel needs.

Choosing the right Tokyo SIM card can make your trip more enjoyable and stress-free. For solo travelers or those who prefer easy setup, BitJoy’s eSIM offers great value, fast activation, and reliable data. Whether you need data for maps, streaming, or staying connected on the go, BitJoy is a smart choice. Get your Tokyo SIM card with BitJoy today and travel confidently.
