Mosaic censorship (モザイク) refers to the pixelation or blurring applied to explicit content in Japanese published works. This is due to Japanese obscenity laws that require censorship of genitalia in published materials. The tag helps readers identify whether content is censored or uncensored. Many doujinshi are published with mosaic censorship and later 'decensored' by fans or released in uncensored versions by the artist. Related tags include 'uncensored' and 'full censorship.'

X-ray (X線) is a visual technique tag where the artwork shows internal anatomy during sexual acts. This allows viewers to see internal ejaculation, penetration details, and other anatomical elements that wouldn't be visible in a normal perspective. The technique is unique to illustrated content and is a significant artistic choice. It frequently appears alongside 'nakadashi' and 'impregnation.'

Paizuri (パイズリ) refers to breast-based sexual acts where the penis is placed between breasts. Also known as titjob or mammary intercourse. This tag is closely related to 'big breasts' as the act typically requires larger breasts to be depicted. Artists use various techniques to show the visual appeal of the act, including compression, jiggle, and facial expressions. The tag frequently co-occurs with 'big breasts,' 'sole female,' and 'blowjob.'
