JAV Terminology Guide for Beginners

New to Japanese adult video sites? Learn key terms: JAV, censored vs uncensored, FC2, JavDB, product codes, and more.

JAV

JAV stands for Japanese Adult Video. Within Japan, the industry more commonly uses the abbreviation AV (adult video); “JAV” is the term most often used outside Japan to refer to the same thing.

The JAV industry is one of the largest adult entertainment industries in the world, with a studio system, performer agencies, and retail distribution comparable in structure to a mainstream film industry — a fact that surprises many first-time observers.

Censored vs. Uncensored

The single most important distinction for newcomers. Censored JAV has mosaic pixelation applied to certain areas of the image. This is not a stylistic choice: Article 175 of Japan’s Criminal Code (1907) prohibits the distribution of “indecent material,” and the industry complies through mosaic censorship, overseen in practice by self-regulatory bodies such as Eirin.

Uncensored content carries no such pixelation. It is typically produced and distributed outside Japan’s domestic regulatory framework — for example, by studios operating abroad or via amateur platforms — which is why uncensored releases form a largely separate market with their own sites and codes. Streaming platforms usually label the two clearly, and many let visitors filter for one or the other.

FC2

FC2 is a long-running Japanese internet services company best known for its blogging and video-hosting platforms. Its adult video section (adult.contents.fc2.com) became famous as a hub for amateur uploads — individual creators rather than studios.

FC2 releases use their own numbering system, with codes prefixed “FC2-” followed by digits (for example, FC2-1234567). Because much FC2 amateur content is uncensored, the prefix has become shorthand among viewers for that style of independent, amateur production.

JavDB

JavDB (javdb.com) is a metadata database, not a streaming site — a distinction beginners often miss. Its purpose is lookup: enter a product code, performer name, studio, or tag, and JavDB returns the release’s details, cover art, cast list, and often magnet download links.

It also categorizes releases (censored, uncensored, Western) and tracks which entries have subtitles or reviews. A similar and equally well-known database is JavLibrary. Databases like these are the reason product codes matter: the code is the key that connects a streaming site, a database entry, and a discussion thread about the same release.

Product Codes

Nearly every commercial JAV release carries a product code — a short identifier printed on the packaging and used across the entire ecosystem. The standard format is two to six letters (usually abbreviating the studio or label), a hyphen, and two to five digits: for example, ABC-123 or SSIS-406.

Codes are the most reliable way to find an exact release. Streaming-site search boxes, databases like JavDB, and community discussions all accept them, which is why experienced viewers search by code rather than by translated titles (which vary wildly between sites).

More Useful Terms

• Chinese / English subtitles (中文字幕) — many streaming sites tag releases that include fan-made subtitles; subtitle filters are common on category pages.
• New release — the latest-uploads feed found on virtually every streaming site; the fastest way to see what’s new.
• Models / actresses — performer directory pages, useful for following specific performers across releases.
• Magnet link — a peer-to-peer download link format listed by databases like JavDB; requires torrent software and carries the usual file-sharing risks.
• Studio / label / maker — the production company behind a release; databases let you browse by studio.

  Amateur (素人) — content featuring non-professional performers; much of FC2’s catalog falls into this category.

• VR — virtual-reality releases designed for headsets; a growing but still niche section on most platforms.
• Compilation (総集) — a release edited together from scenes of earlier titles, often sold at a lower price point.
