How to Call Japan from the US — Country Code +81
Japan's country code is 81 (also written as +81 or 0081). To call Japan from the United States, dial 011 + 81 + area code + local number from a US landline, or +81 + area code + local number from a mobile phone. Drop the leading 0 from the local number. Kinvo connects any Japan number from your browser at $0.20/min — no app, no subscription. For the dialing code itself and number-format reference, see the Japan country code page.
Japanese landline area codes range from 1 digit for Tokyo (03) and Osaka (06) to 5 digits for rural areas, always dialed with a leading 0 domestically. Mobile numbers are always 11 digits starting with 070, 080, or 090, becoming +81 70, +81 80, or +81 90 internationally. IP phones use 050-prefixed numbers.

How to Call Japan From iPhone, Android, or a Landline
From an iPhone
Open the Phone app, press and hold 0 until a + appears, then type 81 followed by the local Japan number. Or use Kinvo in Safari — no dialer permissions needed.
From Android
Open your Phone app, long-press 0 to get +, then dial +81 + the number. In Chrome, open kinvophone.com and call directly without touching your carrier plan.
From a US Landline
Landlines don't have a + key, so use the full exit code: 011 81 then the local number. Check with your phone provider that international calling is enabled to avoid blocked calls.
How to Call Japan For Free
If the person you're calling in Japan has a smartphone with internet access, the cheapest way to call them is free: use WhatsApp, FaceTime, Telegram, Signal, or Google Meet. Both sides need the same app, and calls travel over the internet rather than the phone network — no per-minute fees, no country code needed.
For calling any regular Japan landline or mobile number — the kind that requires dialing +81 — there is no truly free option, because someone has to pay the termination fee to connect the call. Kinvo is the lowest-cost option for dialing Japan phone numbers, starting at $0.20/min with no subscription, compared to $1–$3/min at most US carrier rates.
Japan Calling Tips
Drop the leading 0 from Japanese numbers when dialing internationally. Tokyo area code is 03 (becomes +81 3). Mobile numbers start with 070, 080, or 090. Japan does not observe daylight saving time. Business hours are typically 9 AM to 6 PM JST. Japanese phone etiquette values brevity and politeness.
Why Calls to Japan Sometimes Fail (and How to Fix Them)
When a call to Japan doesn't go through, the cause is almost always one of four issues — not the network. The most common is forgetting to drop the leading 0 from the local number after entering +81. Domestic Japan numbers are written with that 0 at the start; that 0 is the trunk prefix and has no role in international dialing. Dial +81 3 directly, with no 0 in between.
The second is using the wrong exit code from the US. The North American Numbering Plan uses 011 — not 00, which is the international exit code most European countries use, and not the + sign on a landline (which has no + key). From a US mobile, holding the 0 key produces +; that's functionally identical to dialing 011 and works on any GSM or CDMA network worldwide. The third is dialing while your US carrier's international calling is disabled — some pre-paid plans block outbound international calls by default, and you need to call your carrier to enable it (often free, sometimes a small monthly add-on). The fourth is mistaking a +81 number for a fixed-line when it's a mobile or vice versa — the rate difference can be 2-5x, so confirm the number type before long calls.
Japan's domestic time zone matters for whether anyone picks up. Most Japan households answer between roughly 8 AM and 9 PM local time; check the local time before dialing if you want anyone to actually answer.Government offices, banks, and most businesses observe local public holidays and may close early on the day before a major holiday — calls placed during those windows will go to voicemail or unanswered ring regardless of dialing format.
On cost: a 30-minute call to Japan via direct-dial from AT&T, Verizon, or T-Mobile costs $30–$90 depending on whether you have an international add-on. The same call through Kinvo costs $6.05 with no monthly fee. WiFi calling on your phone routes the call through your carrier and bills at carrier rates — it does not save you money on international calls (see WiFi calling vs VoIP).
