12. Anything that violates the design rights, trademark rights, copyrights, patent rights, third party utility model rights, or privacy rights of others.

13. Real-life photography

    *You can still use photography as a background, so long as your 3D model is the central focus.

6 Concealment Processing (Mosaic Processing)

1. In general, it is assumed that concealment processing for censoring will not be a technical property of the image, but rather will obscure details therein in accordance with a visual assessment.
2. Processing will be carried out in the same dimension, and content will be in such a state that it is technologically impossible to return such content to its previous form.
3. Content will be in a state such that the extent thereof contains outlines.
4. Content in which, even though processing has been carried out, details are clearly visible due to transparency, will not constitute concealment.
5. Mosaics shall obscure content with reference to the parameters indicated below.
   In the case of a mosaic of at least four square pixels and an entire image having a lengthwise dimension of at least 400 pixels, the mosaic will cover, in the necessary areas, a surface area of approximately 1/100 of the lengthwise dimension of the entire image.
6. In cases of overpainting, it is assumed that concealment processing will be carried out over the entirety of the necessary area, but this will not apply in cases where said area is obscured as a result of partial processing.
7. In cases where white liquor is used or concealment is otherwise carried out using a design or pattern, it is assumed that concealment processing will cover the entirety of the necessary area, but this will not apply in cases where said area is obscured as a result of partial processing.

7 Examples of Areas Requiring Concealment Processing (Mosaic Processing)

1. Genitals or areas associated with genitals.
2. Areas of genital intercourse or insertion.
3. Areas of anal intercourse or insertion.
4. Areas depicting cutting, laceration or the like in an unnecessarily detailed and excessive manner.
