Earlier this year, in one well-publicized case, porn producers and an actress were arrested for filming at a McDonald’s outlet in Saitama Prefecture.
On May 27, police raided a porn production agency for allegedly filming in the rear of a dump truck in Shibuya. The back was covered by plastic curtains but three cameras filmed the action from 20-meter-tall surrounding buildings. Passersby couldn’t see the actress, but police say people in buildings could see the action, which was the reason for their raid.
Insiders say “public exposure” is one of the most popular porn genres, but they are almost always filmed illegally.
I used to live in Saitama and imagined filming porn in the local McDonalds. Never did it though, which is apparently for the best. =)
