These photos were shared on 9Gag, and we get to take a look backstage at what Japan's porn set looks like. The post claims that the pictures are from a Japanese journalist who spent a day backstage in a porn studio in Japan.
There were 15 to 20 crew members on set, three directors, a best boy, a grip, a makeup artist, two camera operators, and the porn actors. Sounds pretty professional if you asked me.
