Common Questions

1. Do I need a Japan SIM card or can I use my home carrier?
International roaming is usually very expensive ($10–15/day). A tourist SIM or eSIM is far cheaper — typically $10–30 for 2–4 weeks of data.
2. What's the difference between a SIM card and an eSIM?
A physical SIM is a tiny card you insert into your phone. An eSIM is digital — scan a QR code and it activates instantly. Most modern phones (iPhone XS+, recent Android) support eSIM.
3. Which network has the best coverage in Japan?
Docomo has the most extensive rural coverage. SoftBank and au are excellent in cities. For most tourist routes (Tokyo, Kyoto, Osaka, Hiroshima), any major carrier works well.
4. Can I make phone calls with a tourist SIM?
Most data-only tourist SIMs don't include voice calls. IIJmio and Sakura Mobile offer voice-enabled plans. For international calls, WhatsApp and LINE work over data.
5. When should I buy my Japan SIM card?
Buy an eSIM before you leave home — activate it the moment your plane lands. Physical SIMs can be picked up at the airport on arrival, but popular options sometimes sell out.
