Japanese talking in the game? You mean Japanese voice-overs or some kind of narrator on promo clips. That dude talking on this particular clip is pretty annoying but Japanese "dubs" are the best in the world. That's because being a "seiyuu" is a very respected work in Japan, but Western voice actors are just some random people who do it on the side of their "real" work, that's not always true though. There are good dubs, like in Kid Icarus: Uprising and in Persona 4 and in few others.
