Staying connected while traveling in Japan is essential for navigating transportation, finding attractions, and keeping in touch with family and friends.

3. Carry a list of free Wi-Fi spots at your destination to avoid connectivity surprises.

Free Wi-Fi can supplement your connectivity during short stops or in major cities, but for constant, reliable internet while traveling, you may want to consider SIM cards, pocket Wi-Fi, or eSIM options, which we will cover next.

2. Physical SIM Cards: Where and How to Get Them

Physical SIM cards are one of the most reliable and popular options for tourists who want seamless internet connectivity while exploring Japan. They provide stable connections, straightforward setup, and are readily available upon arrival.

Where to Buy SIM Cards in Japan

1. Airports
   • SIM card kiosks and vending machines can be found at major airports like Narita Airport, Haneda Airport, and Kansai International Airport. These kiosks often offer multilingual support.
   • Tip: Purchase at the airport for convenience, as you can start using the internet immediately after arrival.

3. Convenience Stores
   • Some 7-Eleven and FamilyMart stores carry SIM cards, particularly in larger cities. However, the selection may be limited.

   • Buying a SIM card online before your trip allows you to avoid searching for one upon arrival. It’s delivered to your home or hotel and is ready for immediate use. Popular providers include:
     • Sakura Mobile
     • Mobal

Types of SIM Cards Available

1. Data-Only SIM Cards
   • These SIMs offer internet access but do not include phone calls. They are perfect for tourists relying on messaging apps like WhatsApp, LINE, or Facebook Messenger.
   • Cost Example: 7-day plan with 1-3GB of data: ¥3,000–¥5,000.
2. Voice + Data SIM Cards
   • These SIM cards provide both data and a local phone number, which can be useful for making domestic calls or reservations (e.g., restaurants, hotels).
   • Cost Example: 7-day plan with 3GB of data + voice: ¥4,500–¥6,500.
3. Unlimited Data SIM Cards
   • For travelers who need constant access to the internet, unlimited data SIMs are ideal. However, speeds may slow down after reaching a certain usage threshold.

How to Set Up Your SIM Card

1. Insert the SIM Card: Use the SIM ejector tool to swap your current SIM with the Japanese SIM card.

3. Activate: Some SIM cards require you to activate online or through a QR code before use.
4. Start Browsing: Once activated, you can enjoy seamless internet access.
