Famitsu have released their first week estimative/tracking for the release of Xbox Series and PS5.

For those of you that want to read more on the content but translated: https://www.resetera.com/threads/famitsu-playstation-5-sold-118k-units-in-4-days-xbox-series-x-s-sold-21k-units-in-6-days-miles-morales-and-demons-souls-sell-18k-each-japan.328487/page-2

For only the numbers:

PS5 118k in 4 days

Xbox Series X/S 21k in 6 days

Miles Morales 18k

Demons Souls 18k

Remembering that both consoles were sold out on pre-orders and from all we know also on the first week, so demand can't really be determined for sure. The best we can do is say that companies have done a good job with forecasting and that they nearly met their demand, but that can't only be know in the future weeks accompanying the sales.

Just as comparison PS4 first week was 340k and PS3 86k, X1 was 24k and X360 62k

PS4 2019 sales were 929k and X1 were 6k

It would seem that either PS5 was a lot supply constrained or in comparison Xbox Series done an improvement on marketshare on release (it dropped less compared to the first week of X1, while PS5 had a bigger drop, also compared to 2019 sales Xbox done much better this time around).

Well, I was expecting 100k and 20k respectively, so I was lowballing the PS4 a bit, but almost on point with the XSX.

I think PS5 had (and still has) mostly supply issues, explaining the lower numbers.

The XSX and the PS5 are actually low

So confirmation that neither company prioritized Japan very highly for launch shipments. Not that you can really blame them much since it isn't their strongest market, but especially for Playstation this a big step down, compared to the PS4 debut at nearly 3 times as much.

Yes, and no

The PS4 launched in February 2014 in Japan, 3 months after the initial worldwide launch --> more units available at launch.

Low HW supply sure sure (ahem artificial scarcity ahem, ahem), but those software sales are bad. Abysmal.

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).

That's for my "yes" part.

My "no" part is that is not a huge step down from the PS4", it's a global launch all around the world and the console was sold out within 2 hours worldwide, they sold everything they could potentially produce and sell. So yeah, Japan should've have more units perhaps, but that doesn't say much about the actual trends.

Besides the typo, I would say your estimative was very accurate.
