How to Dial Japan
Saving the number in contacts
Start with +81, then use the reviewed national significant number. Remove the first domestic 0 before adding +81.
Calling from abroad
On a mobile, use the + form. If a network requires digits instead, replace + with that origin network's international prefix. Japan's own standard exit prefix for outbound calls is 010; documented alternatives include 001, 0033, 0041, 0061.
Calling a Japan mobile
Remove the first 0 from 090, then add +81.

Exceptions and Routing Notes
Common Japan Formatting Mistakes
- Keeping the leading 0 after +81.
- Assuming 00 is the normal exit code from Japan.
- Treating a carrier-selection prefix as part of the destination number.
Number Portability and Carrier Data
Mobile number portability means a prefix may not identify the current carrier. Treat carrier data as a timestamped lookup result, not a permanent property of the number.
