Zenra is a Japanese expression, literally translated as "completely nude", describing a genre of pornography.
Zenra differentiates itself from other genres in that the subjects are usually groups of women participating in everyday tasks that they might otherwise perform clothed, such as casual scenes with participants playing in an all-nude orchestra in a seemingly oblivious state of mind towards their nudity. Others incorporate the nudity on a more conscious level by doing such things as playing "strip volleyball", where the participants must remove clothing each time the other team scores a point.
In short, use this tag for instances where nudity or partial-nudity (and possibly sex) in public is treated as the norm.
