Not a Robot:
Thanks for make a discussion thread. I haven't had an order from Amazon Japan ship since the spring and they are holding 3 orders. That's why I ordered from CD Japan because I have received shipments from them since COVID. I'm still trying to figure out why Amazon JP isn't shipping to me since they use DHL.
I ordered Machida's photobook from Amazon JP and it arrived quite fast. Maybe you can check if they suspend the shipping to your area due to Covid, since some shipping options are not available due to pandemic.
