To call a Japanese number from a US cell phone, dial the US exit code (011) or the plus sign (+), then Japan's country code (81), followed by the area code without its leading zero, and finally the local number. For example, to call a Tokyo landline such as (03) 1234-5678, you would dial 011 81 3 1234-5678 or +81 3 1234-5678.
How to call a Japanese number from a US cell phone
The complete dialing process requires four parts: the US exit code, Japan's country code, the area code (with the leading zero removed), and the local number. On most US cell phones, you can replace the exit code 011 with the plus sign (+) by long-pressing the '0' key. This makes the international format +81 followed by the Japanese number. For a Tokyo example, the full sequence is 011 81 3 1234-5678 or +81 3 1234-5678.
Understanding Japanese phone number formats
Japanese landline numbers consist of an area code and a local number. Area codes range from one to five digits, while local numbers are typically four to eight digits. Common area codes include Tokyo (3), Osaka (6), Kyoto (75), and Yokohama (45). When dialing from the US, you must drop the leading zero that appears when writing the number domestically. For instance, a Tokyo number written as (03) 1234-5678 becomes 3 1234-5678 after removing the zero. Japanese mobile numbers usually have a 9-digit format, unlike landline numbers which typically have 10 digits.
Step-by-step dialing instructions
- Dial 011 on your keypad, or long-press the 0 key to enter the plus sign (+).
- Enter 81, the country code for Japan.
- Dial the area code without its leading zero. For Tokyo, this is 3; for Osaka, 6; for Kyoto, 75; for Yokohama, 45.
- Enter the local number. For the verified Tokyo example, dial 1234-5678 after the area code.
The complete sequence for that Tokyo number is 011 81 3 1234-5678 or +81 3 1234-5678.
Cost-saving tips for calling Japan
Google Fi's Flexible and Unlimited Premium plans support international roaming in Japan, with cellular calls typically costing around $0.20 per minute while in Japan. Using Wi-Fi calling can be a more cost-effective way to make international calls, as calls to US numbers are often free, and calls to international numbers are billed according to your international long-distance plan. You should also check your carrier's international long-distance plans, as some offer discounted rates or packages for calling Japan. Using internet-based calling services like Skype or Google Voice offer free or low-cost international calling options via the internet.
Checking the time difference before you call
Japan operates on Japan Standard Time (JST), which is ahead of all US time zones. Before dialing, check the current time in Japan to avoid calling at inconvenient hours. A simple time zone converter can help you find the right window for your call.
