In P2P file sharing (eDonkey, Share, Winny, Torrent), users often append descriptive tags:
Because standard JAV never uses lowercase letters as feature flags, this is almost certainly a post‑production filename added by a collector or uploader. AAJ-012 AV D100 l 2 - g b v D
Searching archives (JAVLibrary, DMM, R18 legacy data) does not return a match for "AAJ-012" as an official retail ID. However, "AAJ" does appear in amateur/homemade compilations and some rental-only releases from the late 2000s‑early 2010s, often sold via physical DVD stores in Akihabara. In P2P file sharing (eDonkey, Share, Winny, Torrent),
Possible real match (by similarity):
Thus: AAJ-012 is likely a rare / out‑of‑print indie JAV DVD from a small studio that did not maintain digital distribution. Because standard JAV never uses lowercase letters as
| Segment | Possible Interpretation |
| :--- | :--- |
| AAJ-012 | Most likely the core serial number. In JAV, "AAJ" is not a major studio code. It resembles indie or second‑tier labels (e.g., "AAJ" → A・A・J? Possibly a boutique or rental store code). "012" suggests the 12th release in that series. |
| AV | Explicit marker: Adult Video. Sometimes used in file naming to distinguish from "DVD" or "PPV." |
| D100 | Likely DVD ISO / disc image quality (D = DVD, 100 = 100% untouched / full disc) or a file size indicator (e.g., ~100 min runtime). Could also be a distributor’s internal batch number. |
| l 2 | Lowcase "L" then space then "2" often represents language subtitle track (e.g., Language 2 = English subtitles, or audio track 2). Or "l" = low resolution? Less likely. |
| - g b v D | Most cryptic. Often these letters indicate encoding groups or scene features:
- g = group / gangbang?
- b = bondage?
- v = vanilla? Or video codec?
- D = uncensored? (De-censored). Could be initials of a scene actress. |
Given the spaces and mixed case, a plausible reading:
AAJ-012 AV D100 (main title + format) → l 2 (subtitle track 2 / chapter info) → g b v D (fan‑applied tags).
