This year PS4 has big hitters like bloodborne, ff type 0, dragonball xenoverse (already released), yakuza zero, persona 5, mgs v pp, one piece pirate warriors 3 and biggest anime game of the year Naruto shippuden uns 4. Plus good number of Japan centric games. In home console only Wii U is close to PS4 and it is lacking all of these games. So PS4 has no threat in Japan when it comes to home consoles.
