Consoles are not sold in a vacuum, you have to account for the current tech climate in Japan. Home consoles are not a thing there anymore, not to the extent they once were. Come on, you know this.
Looking at the WW success of the PS4, it's pretty clear that the console itself is not to blame. It's selling as well as it ever could in today's Japan. If it's outpacing the PS3, I think it's pretty safe to say it's doing great. Assessments have to be adjusted according to the environment, you can't simply assign some random target number as a marker for success.
