If you need a prepaid voice SIM, you should get it before leaving Narita or Haneda airport. It will be difficult to find one once you are in the cities.
As of March 2017, there are two prepaid voice SIM card brands available at Narita or Haneda airport. There are many SIM cards sold at the airports but other than these two are prepaid data only SIM cards that do not come with a phone number.
One is from Telecom Square, called Wi-Ho! Data&Voice Prepaid SIM, and the other is from XCOM GLOBAL, called Japan Prepaid SIM. The latter just came out on March 15, 2017.

You don’t need voice feature?
If you think you are ok with a SIM card without voice feature, there are many prepaid data only SIM cards for visitors. You can get them from shops and also from vending machines.
Even with a data only SIM, you can still make voice calls using apps like Whatsapp, LINE, and Skype. Data only SIMs are cheaper!
