FC2 defines the adult category as follows. Please read the following and then click on the “I agree” if you truly mean it.
The content ahead includes "Adult" content which are inappropriate for underage users to watch. “Adult” does not mean only “porn” but also everything that is considered to be inappropriate for people under the age of 18 to watch. Therefore, we prohibit these users from watching adult content. This site is an adult oriented site intended for mature adults. It contains language and images of an adult nature. If you are under 18 years of age or if it is illegal to view adult material in your community, do not enter, press the back button on your browser and leave now.
* We do not state what kind of post should be classified into the adult category. You must decide whether your post should go to the adult category and whether it includes unpermitted expressions or not. Please note that FC2 takes no responsibility for your posts. It is your obligation to judge where your post should belong to. Upon registering a video for the adult category, it is considered to have some kind of adult content.
We may request you to move your post to the adult category when asked to do so by another viewer or when it is clearly judged it should belong to the adult category. If you do not follow such a request, we may move it to the adult category without your agreement. Please remember that we have no obligation to explain such action and are not responsible for anything arising from it either.
