Mobile Phones in Japan

The leading mobile phone providers in Japan are SoftBank (formerly known as Vodafone and J-Phone), NTT Docomo, Rakuten Mobile, and au by KDDI. Additionally, several smaller companies offer affordable cell phone plans and mobile internet services, often utilizing the networks of these major carriers.

Most modern mobile phones should work in Japan, but some older models might face compatibility issues due to different network technologies. There are also some great mobile phone apps that can be very helpful. Here’s what you need to know:

Voice calls

To make voice calls in Japan, your phone must be compatible with Japanese networks. Most modern phones meet this requirement and can be used via international roaming (check with your home provider) or with a SIM card (for unlocked phones). Alternatively, you can use internet-based services like Skype over Wi-Fi.

Data usage

Phones that work for voice calls can also handle data (such as emails and web browsing) through international roaming or a SIM card. Be cautious of high data roaming costs; using Wi-Fi is a cost-effective alternative, with numerous paid and free hotspots available throughout Japan.

Using mobile phones in Japan

SIM cards

Travelers can use their own phones in Japan with SIM cards or eSIM plans, provided their phones are unlocked and compatible with Japanese networks (most modern phones are). Most tourist SIM cards offer data-only services, but you can make voice calls using internet-based services. SIM cards are available at airports, select retailers, and online, with various options for data limits and connection speeds.

Rental phones

Renting a phone in Japan usually requires a photo ID and a credit card. Rental kiosks are commonly found at airports, or phones can be mailed to your hotel or home. Rental fees generally range from 500 to 1000 yen per day, with additional charges for calls, messaging, data, and insurance. Incoming calls are typically free, while outgoing domestic calls cost 50-100 yen per minute. International call rates vary. Same-day rentals are often available if stock permits, and discounts may apply for advance reservations.

Subscription plans (Residents only)

Subscription plans involve monthly billing for phone usage. You can purchase handsets outright or in installments. A residence card is required to sign up for these plans.
