Country code guide
Country code and dialing format for Japan
Calls to Japan use the +81 country code. Use the full international number when you dial so the call can route correctly from the start.
+81
If you are calling Japan from abroad, start with +81, then add the full local number. Use the complete number for the best chance of a clean connection to mobile numbers, landlines, and business lines.
Calls to Japan connect more reliably when you use the complete number. Mobile numbers are often the fastest route to a person, especially in cities like Tokyo, while business lines are easier to reach during local working hours.
Most calls in Japan happen in Japanese. A short script helps when you are calling companies, admissions teams, embassies, or public offices and need to move fast once the call connects.
With a population of 123,210,000 spread across 377,930 km², Japan has different calling patterns across regions. Mobile numbers usually connect fastest, while landlines may require area-specific formatting or city-aware dialing details.
If you are calling about paperwork, deliveries, finance, or support, keep the full contact details ready. The postal code format in Japan is ###-####, which may come up when you speak to a business or government office.
Check the local time, confirm the full number, and place the call when the other side is most likely to pick up. That gives you a better shot at turning the call into a real conversation.
