Does exclusive mean she works for the studio as an employee?

No. It is a fixed-term contract for releases, not employment. The performer is normally represented by a talent agency, which negotiates the contract and continues representing her when it ends.

Can an exclusive performer appear on another label at the same time?

Not during the term — that is what the exclusivity buys. Appearances outside the label are typically limited to non-release work such as events, magazines or streaming, and even those are usually negotiated.

How do I tell if someone was exclusive just by looking at a filmography?

Look for a contiguous run of one code prefix at a steady cadence, with the performer billed at the top of the cover. Scattered prefixes across many labels in the same period indicate the opposite.

What Does It Mean to Be an "Exclusive" Performer?

An exclusive performer (専属, *senzoku*) is contracted to release through a single label for a fixed term, appearing on no rival label during it, in exchange for a guaranteed release slot, production budget and promotion. The arrangement shapes casting, cover billing and code prefixes across the whole industry.

An exclusive performer — 専属 (senzoku) — has signed a fixed-term contract to release her work through one label only. For the length of that term she does not appear in releases from competing labels. In exchange, the label commits to a regular release slot, a production budget above its ordinary level, and promotional weight: cover billing, campaign materials, interviews, event appearances.

It is the single most structurally important arrangement in the industry. It determines who appears on which label, how catalogues are marketed, why code prefixes cluster the way they do, and why a performer's filmography can look completely different before and after a given date.

What does an exclusive contract actually commit each side to?

Two asymmetric bundles of obligations. The performer gives up optionality; the label gives up flexibility and money.

Side	Typically commits to	Typically receives
Performer	Releasing only through that label for the term; an agreed release cadence; promotional duties	Guaranteed release slots, higher production budget, top billing, campaign promotion
Label	Producing and releasing on schedule; funding promotion; centring her in marketing	A recognisable face it alone can sell; a predictable release calendar
Agency	Negotiating and administering the contract; managing schedule and non-release work	An ongoing management relationship independent of the label

We deliberately give no figures here. Contract lengths, per-title fees and cadence commitments are quoted confidently all over the internet and sourced almost nowhere, so treating them as facts would be guessing. The mechanism is well established even where the numbers are not.

What are the casting tiers, and where does exclusivity sit?

Exclusivity is one rung on a ladder of casting statuses, and the vocabulary is worth knowing because it explains billing.

Tier	Japanese term	What it means in practice
Exclusive lead	専属 senzoku	Contracted to one label; carries her own titles; top cover billing
Solo lead	単体 tantai	Carries a title alone, but not bound to one label
Concept lead	企画単体 kikaku-tantai	Leads titles, works across labels, cast for a concept
Ensemble / format	企画 kikaku	Cast into a format or series; billing follows the concept

The ladder is not a quality ranking. It describes contract shape and billing position, and performers move up and down it over a career — including deliberately, since working across many labels can mean more work rather than less.

How can you tell from a filmography whether someone was exclusive?

By the shape of the run, not by any badge. Four signals, in order of usefulness:

One prefix, steady cadence. A contiguous run of a single label's prefix at even spacing is the strongest indicator. Exclusive terms produce dense, regular blocks.
Cover billing. Exclusive performers are foregrounded on covers, usually named prominently, with the label branding secondary.
Sudden prefix scatter. A filmography that abruptly spreads across many labels' prefixes usually marks the end of a term.
Debut positioning. Many performers begin under an exclusive contract, so a filmography that opens with a single-label block is a common pattern.

The badge on the cover — the word 専属 printed on promotional material — is real but inconsistently applied across eras and labels, so treat it as confirmation rather than as the test.

What happens when an exclusive contract ends?

Several things, and they look similar from the outside, which is why guessing is unwise.

Renewal. The same prefix run simply continues.
Move to another label. A new exclusive block begins under a different prefix, sometimes at a label inside the same parent group.
Going freelance. Releases begin appearing across many labels at once, often at a higher volume than before.
Reduced activity or retirement. The run stops. An announced retirement (引退) is a public fact; an unannounced gap is not evidence of anything, and inferring a reason would be exactly the kind of unverified statement about a real person to avoid.

One consequence deserves its own note: stage names sometimes change when a performer moves between labels or re-debuts. A name change severs the connection that name-based search depends on, while leaving the face unchanged.

Why does exclusivity matter when you are searching by face?

Because it shapes both the data and the failure modes.

During an exclusive term, a performer's images come overwhelmingly from one label's promotional pipeline: consistent lighting, consistent art direction, often the same photographer. That produces a tight cluster in face-vector space and generally strong matches. After the term, her images spread across many labels with wildly different treatments — and matching a heavily styled promotional portrait against a handheld frame from a different production is measurably harder.

Name changes are the other reason face search outperforms text search here. Text search requires you to already know the current name; face search does not care what she is called. Our pipeline detects the face, aligns it on five landmarks, encodes it into a 512-dimension vector and compares by cosine similarity, with a threshold of 0.40 for treating two faces as probably the same person.

Boundary worth stating. Our index holds 241,792 faces from 106 sites, resolving to 2,333 named performers (our index, 2026-08 snapshot), and the sampling is skewed: 2,246 of the 2,333 performers take their representative image from a single source site. Biographical coverage is partial too — debut date 59%, birth date 56%, bust size 59%, height 57%, birthplace 31%. We also cannot tell you how many titles any performer or label has released; that is not what a face index measures, and we do not estimate it.

Is exclusivity to the label, the platform, or the agency?

Three different relationships that get conflated constantly:

Relationship	Binds	Duration
Label exclusivity (専属)	Which label may release her work	Fixed term, renewable
Platform exclusivity	Which storefront or streaming service carries a title	Per title or per window
Agency representation	Who manages and books her	Ongoing, usually outlasting label contracts

Confusing the first two is the most common error. A title being available on only one platform says nothing about the performer's contract status — that is a distribution deal between the label and the platform. The agency relationship is covered in how studios and talent agencies actually relate.
