Help me out, how to read the charts? What's in parentheses?

That's the digital sales.

I see. How accurate is all of that information? I find it hard to believe that Pokemon did so very little digitally (and surely someone would have bought GTA5 digitally).

The info imo doesn't contain download cards, MH4 was stated that it had 255k digital sales FW. This data shows less

Download cards are counted as normal sales in Famitsu according to every person in these threads.

yes, looking at pokemon XY further proves it, Downloable cards had a big effect on pokemon xy yet it only has 30-40k out of 3mil? Not including DL cards yes its believable! 

Either way this will definitely help us out more for japan! Killzone vita is one of the only rare 25%+ digital sales on here!

If it has 0, then I guess it's not available on Japanese PSN.

I was the one who posted this, so let me be the one who explains you.

Download cards are included in the physical sales in Famitsu, so the digital sales in parenthesis are just the sales purchased directly from the eshop. Why is MH4 so high an Pokemon so low? MH4 had a lot of stock problems at launch (so many weeks until mid-october), Pokemon didn't have any stock problem. It has been show that Japanese really don't care so much about digital copies, but when stock problems are there, the vision is different. Taking digital sales, MH4 is still above Pokemon (digital sales for november not included yet):

[3DS] Monster Hunter 4 # <ACT> (Capcom) {2013.09.14} (¥5.990) - 3.375.739
[3DS] Pokemon X / Y # <RPG> (Pokemon Co.) {2013.10.12} (¥4.800) - 3.329.718

Other game that had stock problems at launch was FFXIV, as you can see, digital sales also are quite high for this game.

GTAV is not available to the japanese PSN (as kresnik said).

It seems Famitsu managed somehow to get this digital sales information from Sony and Nintendo. And from January, digital sales will be included in their rankings.

tbone51, MH4 was stated to be 255k digital FW combining download cards and eshop sales. It was 150k download cards and ~100k eshop sales. So the next two weeks MH4 sold 120k through the eshop (there were reports that download cards being also out of stock, so it's normal).

I see. I didn't think the MH4 digital numbers were high at all, as I'd assumed 10% would be the norm.

Thanks mate, your information is appreciated.
