Anal intercourse is a common sexual act tag in doujinshi. It appears across nearly all genres and demographics, from vanilla romance to extreme fetish content. The artistic depiction ranges from realistic anatomy to highly stylized presentations. This tag frequently co-occurs with tags like 'nakadashi' (internal ejaculation), 'big breasts,' and various body-type tags. Some artists specialize in anal content, developing signature techniques for depicting the act. The tag covers both consensual and non-consensual scenarios depending on accompanying tags.

Swimsuit (水着, mizugi) is a costume tag covering various swimwear including bikinis, one-pieces, school swimsuits (スクール水着), and micro bikinis. The school swimsuit in particular has a significant following in Japanese fan art. The tag often appears in beach, pool, or water park settings and is commonly paired with 'big breasts,' 'dark skin,' and 'sole female.'

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.'
