3. Ways to Use a Mobile Phone in Japan
3.1 SIM Cards
SIM cards and eSIM plans allow tourists to use their own phones in Japan, provided the devices are unlocked and compatible with Japanese networks. Most tourist-oriented SIM cards offer data-only services without voice calls (except for internet-based calling services).
Options vary in connection speeds, networks used, and data transfer limits. They’re typically available for specific time periods (e.g., one week) or maximum data amounts (e.g., 3GB). SIM cards can be purchased at airports, select retailers in Japan, or online.
3.2 Phone Rentals
Renting a phone usually requires photo ID and a credit card. Many companies have airport kiosks, while others offer hotel or home delivery.
Rental fees vary by company, typically ranging from 500-1000 yen per day. Additional charges may apply for calls, texts, mobile data, and insurance. Domestic outgoing call rates are usually 50-100 yen per minute, with incoming calls free. International rates vary by destination country.
3.3 Subscription Plans (Japan Residents Only)
Subscription plans allow users to pay for usage at the end of each monthly billing cycle. Phones can be purchased outright or on installment plans. A residence card is required to register for a subscription plan.

Observing proper phone etiquette is crucial in Japan:
- Talking on phones in trains, buses, cafes, and restaurants is considered highly disrespectful and may provoke hostility
- Voice calls are only acceptable on long-distance trains in the deck areas at either end of each car
