Big breasts (巨乳, kyonyu) is one of the most iconic body-type tags in doujinshi and manga. It refers to female characters with notably large, exaggerated breasts that often serve as a central visual element. Artists typically emphasize size, weight, jiggle physics, cleavage, and breast-focused activities like paizuri (titjobs) and breast play. This tag spans nearly every genre — from vanilla romance to hardcore fetish content. The artistic treatment varies widely: some artists favor realistic proportions while others push into exaggerated territory. Related body-type tags include 'huge breasts' for extreme cases, 'small breasts' for the opposite aesthetic, and 'paizuri' for breast-focused sexual acts. The tag often appears alongside 'sole female' and 'nakadashi' in heterosexual content.

Yuri (百合) refers to female-female romantic or sexual content. Unlike 'lesbian' which implies real-world orientation, yuri is a genre term specific to Japanese media. The content ranges from soft romantic tension to explicit sexual scenes. Yuri has its own rich ecosystem of tropes and character dynamics. Related tags include 'futanari,' ' ffm threesome,' and 'sole female.'

Lactation (母乳, chichi/nyuusei) is a fetish tag involving breast milk production or breast feeding in a sexual context. This covers both natural lactation and induced lactation scenarios. The tag has a dedicated following and often appears alongside 'big breasts,' 'pregnancy,' and 'milf.'
