1. Physical SIM Cards vs. eSIMs
- eSIM (Recommended): If your phone is compatible, eSIMs are the most convenient. You can download and activate them before your trip, so you have data the second you land.
- Physical SIM: Best if your phone doesn’t support eSIM. These can be pre-ordered online or bought at the airport.
2. Where to Buy
- Airports (Narita, Haneda, Kansai): The easiest but often most expensive option. You’ll find SIM vending machines, dedicated counters (like JAL ABC), and even convenience stores in the arrivals hall.
- Electronics Stores: Stores like Bic Camera and Yodobashi Camera in major cities offer “Japan Travel SIMs” from brands like IIJmio and b-mobile at competitive prices.
- Online Pre-order: Providers like Japan Wireless or Sakura Mobile allow you to order online and pick up the card at an airport counter or have it delivered to your hotel.
3. Essential Tips
- Unlocked Phones: Your phone must be SIM-unlocked by your carrier to use a Japanese SIM.
- Data Only vs. Voice: Most “tourist” SIMs are data only. If you need a voice line (e.g., for making local reservations or for resident registration), Mobal is one of the few that provides a real Japanese number to foreign visitors.
- Coverage: Look for providers using the NTT Docomo or SoftBank networks for the most reliable coverage across both cities and rural areas.
Typical Pricing
- Short-term (7–15 days): Expect to pay between $20 and $40 for 5GB to 10GB of high-speed data.
- Monthly/Long-term: Prices for voice and data plans generally start around ¥1,650 per month.
