It's a gimmick. Yes they pixelate images in Japan. But then you can buy 'de-pixelators' on the black market. Nice way for the Yaks to upsell. Those boys don't look very Japanese: more like gyopo.
It's Japanese pornography law, there ist no a single "legal" pornography been published in Japan without blurred (they call it mosaic) on sex organ. If you see next time a Japanese porno without mosaic, it should be published in foreign country or illegal (less possible). Asian culture, quiet interesting, Japanese has made the most of porns in the world but you can't see their sex organ! What's point then?!
