While I agree Nintendo is making in roads with a lot of companies, I don't think they are taking over Japan.
It seems to me they made the most progress with Sega, Square Enix and Toei Kemco, they are still on Konami's S--- list from what I've seen. And several developers that gotten hot during the days of the PS1 and PS2 seem more willing to gamble on the PS Vita or even the PSP, then try moving products on a Nintendo system.
The only IP we know Nintendo has bought is Fatal Frame/Zero but them securing exclusives like Monster Hunter, Shin Megami Tenshin, Dragon Quest and a few others does help. Although there is no doubt the majority of Nintendo's wealth in the coming years in Japan is going to come from the 3DS dominating the handheld market that controls Japanese gaming culture.
