Credit history with AMEX can be transferred between countries. It seems that usage information for AMEX in Japan can be transferred to the United States. If you have a credit history in Japan but have not yet created a credit card in the United States, you may be able to use this system to create an AMEX card right away. (AMEX cards are introduced in 3, 4 & 5 below)
