Is there a 3G Sim Card that is usable in both Japan and China?

I will be going to Japan and China next month. As I don't want to activate the data roaming on my carrier due to the high charge, I am looking to buy local Sim Card with 3G data plan that is cheap and usable in both Japan and China.

Where and how I can buy them? I am carrying an iPhone 4.

I understand that I can buy Chinese SimCard 3G with data plan in China, but unfortunately with that SimCard comes with a lot of restrictions as to which site I can browse and which site I can't. Is there any other better alternative?

As well, when I was in Japan this time last year, buying a 3G SIM Card in Japan was not possible for non-residents.

The only option seems to be renting a card at the airports, which was not a cheap option.
