Yes, and no
The PS4 launched in February 2014 in Japan, 3 months after the initial worldwide launch --> more units available at launch.
I'm aware of that but it doesn't change the numbers. Sure since they weren't focusing on launching everywhere else at the time it was easier to allocate more stock to Japan, but its not like they couldn't have shipped 300k to Japan this time if they made that a priority. They just decided to focus their initial shipments elsewhere (probably mainly the US).
