For the PS4, I think I posted it in the Famitsu thread broken down by publisher

Most Japanese 3rd Party publishers are down more than 30% in terms of physical sales during the transition from PS3/PSV -> PS4.

The transition hurt companies that had AA titles, most of those saw decline going to PS4 only. So digital isn't really making up the difference in total numbers but it's more profitable for the likes of Capcom and Square who saw growth during this period. 

Lifetime sales of Switch in Japan will be at 25-35M. Nintendo hasn't even lowered the price of the base Switch 3 years into its life... the 3DS they had to slash 30% off to save it during it's the first year... People forget that 3DS wasnt off to a great start when it retailed at 25,000 yen and Nintendo cut the price to 17,000 during its first year. Switch is still 29,000 yen in Japan, right now you are again paying premium from scalpers if you don't want to rely on lotteries. 

Japan continues to be a price-sensitive market - so as soon as they do, once again they will have supply problems. This is the same reason why PS5 will struggle if it's 40,000 yen.

At the moment Nintendo could ship 100K per week at the same price as launch. And this is happening in the summer when generally we haven't seen such sales since forever.. What happens if they announce a big DLC for Animal Crossing to coincide with Obon. 

During 2012 when Animal Crossing New Leaf launched, 3DS achieved 5.5M units, at this point of the year the 3DS was at 1.8M units, right now the Switch is at 2.3M and demand isn't slowing down. That was 3DS's best year on the market. Right now with 6 Months to go:

Animal Crossing: New Horizon = Animal Crossing: New Leaf + New Super Mario Bros. 2 + 600K

New Horizon's domination is unprecedented, by the end of the year the game could very well be at 7M physical sales minimum. No company in Japan can compete with this. When Nintendo release a Christmas themed Animal Crossing Bundle to go with their Winter Themed expansion they'd sell out even without lowering the price... This year is probably heading for 6M in Japan if Nintendo can supply that much. 

Good post :) I agree

For Nintendo concentrating all their franchises into one device has helped, that device also being good is the underplayed aspect. The Switch is used by the majority of users both portably and docked that proves that this was the correct concept. But the main thing that sold the 3DS and now Switch is Nintendo's output. You cannot play Animal Crossing, Splatoon, Smash, Mario Kart, Zelda, Pokemon, Mario, Ring Fit on anything else... and that for Japanese audience at this price is enough to stop the decline. 

Sony has the pulse of Western Market with its output but Spiderman or God of War will never sell over 1M physical in Japan because they are not on the Switch.  In the end of the day Sony hasn't really been a Japanese managed company for a while and their gaming output and global strategy is focused on what has made it the dominant platform in the West and that's just outplaying Microsoft for the past few years.  

I'm sure when streaming becomes profitable for Sony they will reenter the portable space with their AAA efforts in Japan but they would still be a niche, because they are Western focus by design. 

What I'm quoting is Physical Sales, Wiki could mention official shipped+digital numbers from official news, which is different. When discussing such numbers I'm looking at Famitsu numbers, since those are the most complete numbers we have for the vast majority of titles. 

Japan is slower to adopt digital and for the most Japanese 3rd Party titles post-launch also competes with 2nd hand sales. This is one of the reasons most Nintendo games never go on sale, while an over-shipped game like FFXV never sells any additional copies in Japan(you can buy it 2nd hand for Y500). Nintendo rarely over ships games, while some publishers do but it's retailers that actually eat the loss. 

While in the West over 50% of people are buying games digitally in Japan even for the PS4 that percent is at 30% max for most titles. 

Do we have any idea on how well the streaming RE7 and couple other games done in Switch in Japan?

Dude,.... Mate,...... Where did the Wii u sell well? If you wanna sound credible, don't use Wii u as a standard for sales. It just wasn't appealing while switch is so damn appealing

Yeah... I don't fully agree with this.

I mean, it's true that Sony presence in Japan has been waning and becoming smaller every gen(even if the 8th gen is going to do about the same as the 7th gen), but the reason why Sony is not doing as well there as it used to do is simply because it hasn't adapted its hardware well enough to Japan evolving tastes.

I mean, just look at the Switch. It will surely pass 20 million units sold there, and has a real shot at reaching 30 million. And is a gaming console as any that have been ever produced, either by Sony or by Nintendo. Just because mobile is doing better, dosen't mean the classic gaming experience can't grown on it's own terms.

Why are Japanese gamers choosing the WiiU version of Switch over the 3DS version even though it's cheaper, smaller and has better battery life?

Google is your friend :P

I have no idea. But it does support my theory no? How about we look at hard facts and statistics before we straw man.

oh okay. At first I thought Famitsu didnt combine a specific PS4 SKU or from a certain retail outlet. 

I never asked for the validity of stats. I just said the Wii U is not a good barometer.

What he says is that the handheld thing is not sufficient as an explanation for the japanese market. That the WiiU was an unappealing console for many doesn't change the comparison between Switch Lite and OG Switch.
