Kooban (Police Box)
Kooshuu-denwa (Pay phone)
You maybe need a telephone card to use a pay phone in Japan. Those for coins are seldom here. However, it is free if you want to call to police (No. 110) or fire station (No. 119). As a police box is here and there in Tokyo, it is OK to ask them directly.
