How true is the notion that the Japanese government tried (or is still trying) to hide their atrocities during WW2 to their citizens?

With the internet today I would imagine that it would be very hard to do yet I read about plenty of anecdotal evidence from redditors who have supposedly been living in Japan for a long time.

EDIT: To clarify, my question is if they did and if they are still doing it today.
