>>4349001Amex is hit and miss with JP websites, and getting it in some places that are not America can be a bit of a challenge that most people won't bother going through. I did get one here in Europe for Melonbooks specifically, but haven't tried with other sites yet. I wish websites would just accept Amazon Pay (JP) like DMM, very convenient.
But yeah, with Visa and MC cut off, revenue from a Fantia targeted at foreigners would drop to approximately zero.
