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.

Dark skin (黒人, kokujin / 日焼け, hiyake) refers to characters with darker skin tones. This includes naturally dark-skinned characters, tanned characters (tanlines), and characters with dark skin as an artistic choice. The tag covers various ethnicities and skin tones. It's often paired with tags like 'tanlines,' 'big breasts,' and 'big ass.'

Bikini (ビキニ) is a costume tag specifically for two-piece swimwear. This is more specific than 'swimsuit' which covers all swimwear types. The tag covers various bikini styles including string bikinis, micro bikinis, and sport bikinis. It frequently appears alongside 'big breasts,' 'dark skin,' and 'beach.'
