Essential quotes: 

"DoCoMo’s forthcoming launch of the world’s first mobile handset with a built-in credit card chip"

...

"The move exploits the growing popularity of DoCoMo’s range of “e-wallet” handsets that allow the phones to be charged-up with pre-paid cash, waved over a contactless reader and used for a range of purchases in shops and restaurants. More than 11 million customers are regular users."

So if I understand well, one would swap one's phone over specific readers (JP only) just like with a normal credit card and voila !

The extension to other credit card issuer such as JCB will come in a 2nd phase that would broaden the usage quite some.
