You're going to have to do better than a completely unspecific, unsourced, pretty much useless web site.
If you're going to make such specific claims, you need to give specific costs - how much are people paid on average? How long was the game in development? What kind of extra costs do Japanese companies have that differ from American companies in terms of perks, benefits, and others?
Are you seriously suggesting that an HD Resident Evil game, perhaps Resident Evil 5 and 6, only cost around $3 million to create?
Resident Evil 5 had around 400 people working on it.
Resident Evil 6 had around 600 people working on it.
I....just....you do the math there.
