The preview goodies keep on coming as the Apple Pay Japan rollout approaches. The JR East View Card site states “Apple Pay will be available with a free software update coming in late October 2016,” confirming that the launch coincides with the iOS 10.1/Watch OS 3.1 update. Other Apple Pay related Japanese credit card sites are being updated with the tag line.
Apple Pay is still not enabled for the Japan region in the latest developer release and may not be turned on until the official release.
