In general, it is recommended to use the internet and the various smartphone messaging apps to communicate with your friends and relatives both in your home country and in Japan. Should you ever need to make some local calls, you can use a public payphone.
Having said that, let's now deepen all the possible alternatives to make a call and communicate in Japan, one by one.
Roaming with your mobile phone and your sim card
Once you arrive in Japan, as soon as your smartphone connects to Japanese networks for the first time, you should receive a message from your operator with a summary of the costs for making calls, texting and using the data connection while roaming. These costs are generally very high, unless you have activated an international plan beforehand.
Today, different operators in different countries offer convenient international plans that usually include a certain amount of gigabytes to surf the internet and a certain number of minutes to make calls. Whether or not this alternative is convenient depends on your needs, your country and your mobile network operator.
Call using messaging apps and voip services
Quite simply, if you don't need to call any phone numbers, and all your contacts, whether foreign or Japanese, use one of the many messaging apps, you'll just need your smartphone and an internet connection to communicate with anyone. More information about the internet in Japan.
Most used messaging apps in Japan
Whatsapp is almost unknown in Japan. Facebook is used, but not by everyone. In contrast, all Japanese people use an app called LINE to chat and communicate with each other. If you want to easily communicate with Japanese friends, we recommend installing this app, also available in English.
Skype and other voip services
The voip apps have fallen into disuse, given the spread of messaging apps for smartphones. However, they continue to be very useful if you need to call a phone number.
By purchasing Skype Credit, you can call landlines and mobile phones worldwide from your smartphone or PC via your Skype account. The rates are a few cents per minute, with 1 dollar you can call for 30 minutes or so. Check out the rates to call Japanese numbers.
Call from public telephones
Public telephones in Japan are still very common to see, you can easily find them in many places: in railway stations, in shopping centers, in museums and amusement parks, or even along some roads.
Although their use is very rare nowadays, unlike other countries in the world, no disposal plan is currently planned, as they are part of a whole series of procedures that are activated when an area is hit by a natural disaster (for example earthquakes). Depending on the gravity of the situation, the network of Japanese public telephones is set up to be "unlocked" in a certain area and allow free calls for anyone in need.
There are two types of payphones in Japan, which differ in color: the green phones and the grey phones. Somewhere (especially in country towns) one could still find very old and fascinating pink telephones.
The green telephones are the most common and there are two types, analogue and digital, and only digital ones are enabled for international calls.
The gray phones are all digital, they are more sophisticated and also allow data communication, and they are usually enabled for international calls.
If a telephone is enabled for international calls, the message "Can be used for international calls" will appear on the display.
All public telephones, green or gray, can be used via phone cards or with coins. Coins of 100¥ and 10¥ can be inserted. For 100¥ coins, no change is given if you don't use all the minutes available, if you insert more than one 10¥ coin, and you don't use all of them, you will receive the change.
Phone cards in Japan
Calling cards can be bought in konbini (convenience stores) or in kiosks inside the stations. There are two denominations, 500¥ and 1000¥.
How much does a call from Japanese payphones cost?
Calling from public telephones is quite convenient if you need to call someone in Japan.
For example, many hotels and ryokan in rural locations (mountain areas, spa areas, etc.) often come to pick up customers at the nearest train station and you may need to call to inform them that you have arrived. Or you have to meet with a Japanese friend in a certain place but you can't find him or her, and you don't have internet on your smartphone outside the hotel.
International calls are very expensive, unless you use a dedicated prepaid card (see next paragraph).
Below is a table with all the rates, which vary according to the distance of the number called and the time slot.
The table lists the maximum call length in seconds, for every 10¥ you insert.
Distance / Time of Call
In-Prefecture Long-Distance Calls
Up to 20 km
Over 160 km
Use prepaid phone cards for international calls
There are various types of prepaid phone cards available on the market, to be used through traditional telephones, for example a public phone or the phone in your hotel room. You call a certain number indicated on the card, follow the instructions and then enter the number you want to call.
You can buy this kind of phone cards directly in Japan, for example in the arrivals area of international airports, or in many konbini (convenience stores) scattered around the cities, but you could also buy them in your home country if you think they are cheap.
