Schools are meant to provide a safe environment for students, but that doesn't seem to be the case for one primary school in Japan. 

According to Japanese media PRIME, they were informed by netizens that a recently released adult video (AV) was filmed at Sanshi-no-mori Park in Tokyo.

The issue? The park is connected to a nearby primary school, and young children often visit the area for walks during the day.  

As if that's not bad enough, the entrance of the school was featured on the cover of the porn flick, and apparently a scene was shot there as well.
