Some of the Best Apps to Use to Call Locally in Japan

It is always best to be prepared when embarking on your study abroad journey. Especially if you will be away for weeks, even months. Staying connected with family and friends back home will help you adjust to your host country. It is also important to know how to stay connected with people in Japan, especially in emergency cases when you may have to call hospitals, emergency services, KCP administration or staff, or any Japanese local number.

There are several apps you can download to call local landlines and mobile phones in Japan.

If you are using your laptop, tablet or mobile phone in Japan, chances are, you will be using a number from your country of origin unless you decide to purchase a local prepaid service in Japan.

Using a U.S. call service app to dial a local Japanese number would usually entail dialing:

011 – the U.S. exit code , which needs to be dialed to make a call to Japan which is considered an international call if you’re using a U.S. number.

+81 – Japan calling code.

Area code – depending on which part of Japan you’re calling. Refer to Japan area codes for listing.

Phone number – whether landline or mobile phone. Phone numbers in Japan always have ten digits regardless of the area code’s length. Mobile phone numbers start with 090, 080, or 070 and consist of eleven digits.

i.e. (USA exit code)(Japan calling code)(area code)(phone number)
