That's the standard for official, legal Japanese porn. You can have the craziest **** going on - ***** assault, **********, schoolgirl ***********, ******, etc - but pussies and cocks must be blurred.
There is more and more uncensored material being produced with Japanese adult performers - and Maria's done several - but the vast majority of official, legal, commercially produced Japanese porn is going to have the mosaics - which need to be a certain thickness, though "Ultra-Thin Mosaic" is a selling point on some Japanese porn.
