The Step-by-Step Guide to Calling Japan
Making an international call requires a specific number sequence. This ensures your call connects to the right country and person. Getting this sequence correct is the first step to a successful conversation. Here is how it works for both landlines and mobile phones.
The Core Dialing Formula
Every international call follows a standard pattern. You begin with an exit code to signal you are calling abroad. Next, you add the destination’s country code. Then comes the local area code, followed by the subscriber’s number.
The complete formula looks like this:
- UK Exit Code: 00 or +
- Japan Country Code: 81
- Japanese Area Code: (e.g., 3 for Tokyo, without the leading 0)
- Local Phone Number: The final set of digits.
Calling from a UK Landline or Mobile
The process is nearly identical for landlines and mobiles. The main difference is how you enter the UK exit code. Mobile phones offer a universal symbol for this.
- Dial the UK Exit Code. For landlines, dial
00. For mobiles, you can press and hold0to get the+symbol. The+works globally. - Enter Japan’s Country Code. Immediately after the exit code, dial
81. Your number should now look like0081or+81. - Add the Japanese Area Code. Dial the area code for the city you are calling. Crucially, you must omit the leading
0. For instance, Tokyo’s03area code becomes just3. - Dial the Local Phone Number. Finish by entering the rest of the person’s phone number.
Example for a Tokyo landline (area code 3): 00-81-3-1234-5678 or +81-3-1234-5678.
Example for a Japanese mobile (prefix 90): +81-90-1234-5678.
Understanding Japanese Phone Numbers
Japanese phone numbers have a distinct structure. Knowing this format helps you avoid dialing errors. Landline and mobile numbers follow different patterns. Understanding these details ensures your call connects on the first try.
Japan’s Country Code: The Essential +81
Japan’s country code is always 81. You must use this number every time you call Japan from another country. It directs your call through the global telephone network to Japan. Always place 81 right after your exit code (00 or +).
A Closer Look at Japanese Area Codes
Area codes in Japan identify specific cities and regions. They range from one to five digits long. When calling from the UK, remember to drop the first 0 from the area code. For instance, Tokyo’s 03 area code becomes just 3.
| City | Area Code (to dial) |
|---|---|
| Tokyo | 3 |
| Osaka | 6 |
| Kyoto | 75 |
| Nagoya | 52 |
| Yokohama | 45 |
| Sapporo | 11 |
Landline vs. Mobile Number Formats
Japanese phone numbers usually have a total of 10 digits after the country code. However, their internal structure differs.
- Landline Numbers: These include an area code. The format is typically
(Area Code) - XXXX - XXXX. For a call to Osaka, it would be+81-6-XXXX-XXXX. - Mobile Numbers: These do not use city area codes. Instead, they start with a prefix like
70,80, or90. The format is+81 - (Prefix) - XXXX - XXXX. For example:+81-90-1234-5678.
When you call a mobile number, you use the full 10-digit number after +81.

Planning Your Call: Time Zones and Costs
Knowing how to dial is only half the battle. You also need to consider when to call and how much it will cost. Japan has a significant time difference from the UK. Additionally, traditional international call charges can be very high.
Navigating the Time Difference
Japan operates on Japan Standard Time (JST), which is GMT+9. The UK uses Greenwich Mean Time (GMT) in winter and British Summer Time (BST) in summer.
This creates a large time gap:
- During UK Winter (GMT): Japan is 9 hours ahead.
- During UK Summer (BST): Japan is 8 hours ahead.
For business calls, aim for standard working hours (9 AM to 5 PM JST).
| Your UK Time | Japan Time (JST) | Notes |
|---|---|---|
| 8:00 AM | 5:00 PM (GMT) | End of the Japanese workday. |
| 9:00 AM | 6:00 PM (GMT) | Good for catching someone after work. |
| 12:00 PM | 9:00 PM (GMT) | Late evening in Japan. |
The best time for business calls is between 8 AM and 10 AM in the UK. For personal calls, early mornings in the UK align with evenings in Japan.
The Hidden Costs of Traditional Calls
Calling Japan from the UK with traditional carriers can be expensive. Rates often range from £0.50 to over £2.00 per minute. These costs add up quickly, especially during long conversations. Many providers also charge connection fees. This can lead to surprisingly high phone bills. It is always wise to check your provider’s rates before you call.
