Before you head off to Japan make sure that you know who your Network providers roaming partner is in Japan. There is a good chance that your mobile phone will work in Japan, although you may not like the exorbitant usage charges for the voice and data.

When arriving at the airport make sure your phone is in airplane mode, as you may incur usage charges immediately after connecting to the network. Because of agreements with international carriers, text messages may make it through, which you will be charged for.  The airports are full of phone rental places,  although they are expensive and may not offer what you want.

Acquiring Data and Minutes

The process is quite painful, as you cannot acquire a SIM card with pre-paid data and minutes on it, since Japan law does not allow for pre-paid SIM cards with minutes on them.  Most of the rental places in the airport will only offer one of the following: an iPhone with minutes and data (the insurance to protect the phone is expensive, and you have to set it up with your contacts, apps...), data only SIM card (with a throttle after 100mb per day, or a 7 day plan) or a hotspot (with a throttle after 100mb per day...).  All three options are quite high in price, therefore may want to head to an electronics store, such as Yodobashi Camera.  Note that SIM card vending machines exist in hidden locations at some (maybe all) of the airports, though you may need to inquire to find them.

At the electronics store, for So-net and IIJ data-only SIM cards the prices are as follows (currently for the DOCOMO network): 1GB for 3000 yen, 2GB for 4000 yen and 3GB for 5000 yen.  Note that the major cell network providers do not sell them directly to customers.

To obtain phone service, setup a Skype account, and obtain a local phone number if you intend on having locals (Japan natives) call you.  Skype asks the purchaser to sign (a checkbox) that they are a local resident, but it does not appear that this is verified.
