Anime (Japanese: アニメ; IPA: [aꜜɲime] ⓘ;[a] derived from a shortening of the English word animation) is animation originating from Japan. Outside Japan and in English, anime refers specifically to animation produced in Japan.[1] However, anime, in Japan and in Japanese, describes all animated works, regardless of style or origin. Many works of animation with a similar style to Japanese animation are also produced outside Japan. Video games sometimes also feature themes and art styles that may be labelled as anime.

[...] A subset of adult anime works featuring pornographic elements are labeled "R18" in Japan, and are internationally known as hentai (originating from the Japanese word for pervert (変態, hentai)). By contrast, some anime subgenres incorporate ecchi, sexual themes or undertones without depictions of sexual intercourse, as typified in the comedic or harem genres; due to its popularity among adolescent and adult anime enthusiasts, the inclusion of such elements is considered a form of fan service.[87][88] Some genres explore homosexual romances, such as yaoi (male homosexuality) and yuri (female homosexuality). While often used in a pornographic context, the terms yaoi and yuri can also be used broadly in a wider context to describe or focus on the themes or the development of the relationships themselves.[89]

Hentai (Japanese: ヘンタイ) is a style of Japanese pornographic anime and manga. In addition to anime and manga, hentai works exist in a variety of media, including artwork and video games (commonly known as eroge).

The development of hentai has been influenced by Japanese cultural and historical attitudes toward sexuality. Hentai works, which are often self-published, form a significant portion of the market for doujin works, including doujinshi. Numerous subgenres exist depicting a variety of sexual acts and relationships, as well as novel fetishes.

Ecchi (エッチ, etchi; pronounced [et.tɕi]) is a slang term in the Japanese language for playfully sexual actions. As an adjective, it is used with the meaning of "sexy", "dirty" or "naughty"; as a verb, ecchi suru (エッチする or Ｈする) means "to have sex", and as a noun, it is used to describe someone of lascivious behavior. It is softer than the Japanese word ero (エロ from "Eros" or "erotic"), and does not imply perversion in the way hentai does.[citation needed]

The word ecchi has been adopted by western fans of Japanese media to describe works with sexual overtones. In western culture, it has come to be used to refer to softcore or playful sexuality, as distinct from the word hentai, which connotes perversion or fetishism.[2] Works described as ecchi by the western fans do not show sexual intercourse or genitalia, but sexual themes are referenced. Ecchi themes are a type of fan service, and can be found in most comedy shōnen and seinen manga and harem anime.[3][4]

In Japanese popular culture, lolicon (ロリコン, rorikon) is a genre of fictional media which focuses on young or young-looking girl characters, particularly in a sexually suggestive, fetishistic or erotic context. The term, a portmanteau of the English-language phrase "Lolita complex", also refers to desire and affection for such characters (ロリ, "loli"), and their fans. Associated mainly with stylized imagery in manga, anime, and video games, lolicon in otaku culture is generally understood as distinct from desires for realistic depictions of young girls, or real young girls as such,[1][2][3] and is associated with moe, or affection for fictional characters, often bishōjo (cute girl) characters in manga or anime.

The phrase "Lolita complex", derived from the novel Lolita, entered use in Japan in the 1970s. During the "lolicon boom" in erotic manga of the early 1980s, the term was adopted in the nascent otaku culture to denote attraction to early bishōjo characters, and later only to younger-looking depictions as bishōjo designs became more varied. The artwork of the lolicon boom, which was strongly influenced by the styles of shōjo manga, marked a shift from realism, and the advent of "cute eroticism" (kawaii ero), an aesthetic which is now common in manga and anime broadly. The lolicon boom faded by the mid-1980s, and the genre has since made up a minority of erotic manga.

Since the 1990s, lolicon has been a keyword in manga debates in Japan and globally. Child pornography laws in some countries apply to depictions of fictional child characters, while those in other countries, including Japan, do not.[4] Opponents and supporters have debated if the genre contributes to child sexual abuse. Culture and media scholars generally identify lolicon with a broader separation between fiction and reality within otaku sexuality.
