How to Dial International Numbers from Japan
To place an international call from Japan, you need to dial the exit code followed by the destination country code and then the local number. The exit code for Japan is 010. If you are using a mobile phone, you can also use the plus symbol (+) instead of the exit code, and your phone will automatically convert it.
Drop the foreign trunk prefix (often 0) after the country code; do not drop Japan's own 0 when dialing domestically.
Dialing Examples
- Mobile: 010 1 212 555 0123 (Japan to US mobile/landline)
- Landline: 010 44 20 7123 4567 (Japan to UK landline)
Toll-free numbers: Foreign toll free numbers (e.g., 800, 888) usually do not work from Japan unless specifically enabled by the destination provider.
Before You Call
There are a few things to check before making international calls from Japan to ensure your call connects successfully and you understand the costs involved.
- •Ensure international calling (IDD) is enabled on your mobile or fixed line; some plans block IDD by default.
- •Dial carrier selection code (optional) + 010 + country code + number, or use + on mobiles.
- •Prepaid SIMs may restrict IDD or require identity verification and sufficient balance before calling abroad.
- •Corporate and hotel PBXs may require a prefix (often 0 or 9) before 010 or + for external lines.
- •VoIP and app based calls usually only need data access; no 010 prefix or IDD option required.

Cost Considerations
Ways to Call Internationally from Japan
There are several methods available for making international calls from Japan. Each has its own advantages and drawbacks in terms of cost, convenience, and call quality.
Carrier IDD (010 or carrier code + 010)
Call directly from mobile or landline using exit code, country code, and number; billed by your Japanese carrier.
Drawbacks: Higher per minute rates, possible connection fees, and complex rate tables by destination.
Calling cards
Dial a local or toll free access number, enter PIN, then dial the international number.
Drawbacks: Access numbers may not be toll free from mobiles; quality and advertised minutes can vary.
Fixed line international service (e.g., NTT, KDDI)
Register your landline with a chosen international carrier and dial its prefix before 010.
Drawbacks: Requires setup and sometimes contracts; less flexible than app based calling.
