Public telephone booths for disabled persons can be found in the public facilities and streets of Tokyo. Such telephones booths are usually wide and easy to open. The telephones are installed at a lower height. There are also some phones in which one can adjust the volume .

International calls can be made from public phones which are identified as international telephones by using 100 yen coins or telephone card. To make an international call, dial a long distance access number, the country code and the number that you want. The access numbers of the different carriers are 001 (KDD), 0041 (JT), 0061 (IDC) and 0033(NTT COMMUNICATIONS). The rates charged by these carriers vary. Direct calls are 40% less expensive from 23:00 until 8:00 regardless of the carrier. You can place person to person calls, collect calls and credit card calls only through KDD by dialing 0051 from anywhere in Japan. If you need directory assistance from a foreign country, dial 0057. Such directory assistance is free.

When you use 1,000 yen cards (this card is actually valued at 1,050 yen), your call is charged per 100 yen unit and points of 50 yen are always left on the card.
If you buy a "Super World Card" issued by KDD which can be bought at its office or Seven-Eleven stores, you can use it even at green public phones which are not international phones for making international calls. Home Country Direct Service is available from any public phone. This service will let you get in touch with an operator in your home country and place a credit card or collect telephone call.
