What is the country code for Japan?
+81 is Japan's call sign to the world. Add it after your own exit code and any Japanese number is within reach. The one rule that trips up newcomers: the leading 0 that every domestic number wears at home gets retired the moment you cross the border. Tokyo's 03-1234-5678 becomes +81 3 1234 5678 abroad — the 0 was always a domestic courtesy, not part of the real address.
Code +81 werd toegewezen Japan door de ITU onder het E.164-plan. De “+” betekent “bel uw lokale internationale exitcode”; op een mobiel: houd ingedrukt 0 om het te typen.
Ze betekenen alle vier hetzelfde: ze verbinden uw oproep Japan.
How to call Japan from anywhere
Think of it as four neat segments, assembled in order: your exit code, then 81, then the area or mobile code with its leading 0 removed, then the local digits. Get the sequence right and it connects on the first try — exactly the kind of reliability Japan expects.
Volledig voorbeeld: +81 03 XXX XXXX — laat de lokale voorloop 0 vallen als u vanuit het buitenland belt.
Japan phone number format explained
At home, every Japanese number opens with a 0 — the trunk prefix — which falls away for international dialing. Count the digits and you'll find a tidy logic: landlines run 10 digits with the 0, mobiles run 11. There's a quiet hierarchy here too — the bigger the city, the shorter its area code.
Vaste lijn
Area code (1–4 digits, starts with 0) + subscriber number. The major hubs claim the shortest codes: Tokyo 03, Osaka 06. Format example: 03-1234-5678 → +81 3 1234 5678.
Mobiel
Mobiles open with 070, 080 or 090, then 8 digits. Format example: 090-1234-5678 → +81 90 1234 5678. IP phones sit on 050; toll-free lines on 0120 / 0800.

Japan mobile network prefixes
The prefix after +81 tells you which network issued the SIM — though number portability means it no longer guarantees the operator.
NTT Docomo
au (KDDI)
SoftBank
Rakuten Mobile
Japan time zone
One nation, one clock. From Okinawa to Hokkaido, Japan runs entirely on Japan Standard Time (JST), UTC+9, and has never adopted daylight saving — so the offset you memorize in January still holds in July. No spring-forward arithmetic, no autumn surprises.
Punctuality is currency in Japanese business, so land your call inside working hours. US callers catch Japan's evening with an early-morning dial; UK and European callers reach the Japanese late afternoon between 08:00 and 10:00 their time. Offices keep 09:00–18:00 JST.

Common mistakes when calling Japan
Bijna elke mislukte internationale oproep is een formatteringsprobleem, geen netwerkprobleem.
Trusting the prefix to name the carrier: Japan was an early mover on number portability, so 090, 080 and 070 reveal nothing about whether a line lives on Docomo, au or SoftBank
old assumptions simply break.
Keeping the leading 0: Internationally, the trunk-prefix 0 has to go (03 → +81 3)

Swapping Tokyo and Osaka codes: Tokyo is 03, Osaka is 06
one transposed digit sends you to the wrong metropolis.
Mis-splitting the number: Groupings shift by line type (03-1234-5678 vs 090-1234-5678); the spacing is decorative, the digit count is law

Adjusting for a summer clock that doesn't exist: Japan never observes DST, so leave the offset at UTC+9 all year

Tips to reduce the cost of calling Japan
Route over VoIP or a virtual number and sidestep premium per-minute international tariffs entirely.
Favor landlines when you can
termination to a Japanese mobile often carries a steeper rate.
Respect the 09:00–18:00 JST window so calls connect first time, sparing both sides the missed-call shuffle.
Hold a Japanese DID so your contacts dial you at a familiar local rate.

Japan +81 — FAQ
Why does Tokyo get a one-digit area code while smaller towns get four?expand_more
Japan assigned the shortest codes to its busiest hubs — Tokyo is 03, Osaka 06 — so size and seniority are baked right into the numbering.
Why can't I tell Docomo from SoftBank by the number anymore?expand_more
Japan adopted mobile number portability years ago, so 070, 080 and 090 now float freely between Docomo, au, SoftBank and Rakuten — the prefix has stopped being a clue.
What exactly is the 0 I keep being told to drop?expand_more
It's the domestic trunk prefix. Inside Japan you dial it; from abroad +81 takes its place, so 03 becomes +81 3.
How do I call Japan from the US?expand_more
Dial 011 + 81 + the number minus its leading 0 — for example 011 81 3 1234 5678.
How do I call Japan from the UK?expand_more
Dial 00 + 81 + the number with the leading 0 removed.
Do Japanese mobiles and landlines have different lengths?expand_more
Yes — counting the leading 0, landlines run 10 digits and mobiles run 11. Mobiles open with 070, 080 or 090.
Does Japan ever change its clocks for summer?expand_more
No. Japan has never run daylight saving, so JST holds at UTC+9 the whole year.
Can my business get a real Japanese number even without an office there?expand_more
Yes — MCM provisions genuine local Tokyo, Osaka and other Japan DIDs you can route to any team, anywhere.
