Nikon Japan is already warning about Z50II camera supply shortages (for both body only and lens kits) on their website. As a result, they are now offering 10% off coupon code for customers in Japan:
“Z50II [Coupon Distribution]” has received many more orders than expected, so it may take some time to deliver. Thank you for your understanding. We are distributing a 10% off coupon (worth 14,520 yen) that can be used when purchasing “Z50II”.
