According to this linked kbase article, iPhone 3Gs sold in Japan are carrier-locked to SoftBank. Carrier-locked phones cannot be used with a SIM card from another network, so the answer is, "No." If you buy an iPhone in Japan, you'd need to sell it there and buy another one here to use it on the US network (unless you keep the SoftBank account and pay the exorbitant international data roaming charges).
So this is the result of a Softbank policy, not Apple?
A result of the negotiations between SoftBank and Apple, subject to Japanese law. Unlocked iPhones are sold in select countries or locked iPhones can be unlocked by the carriers in those countries, as indicated in the kbase article I linked above (e.g. Italy, Belgium, Hong Kong). In that case, those phones could be used with an AT&T or T-Mobile SIM card in the USA, for example.
But, there's another wrinkle as well - unlike other Apple products, the iPhone warranty is not worldwide. iPhone service can only be obtained in the country where the iPhone was purchased.
