Copyright Management for Illustrators

This section organizes how copyright arises, who it belongs to, and under what circumstances it transfers.

The moment an illustration is created, copyright automatically arises with the creator — the illustrator themselves. This is called "original acquisition of copyright." Unlike patent rights or trademark rights, copyright arises without registration. Article 17 of the Copyright Act establishes that the person who creates a work becomes its author, and even an illustration created by a freelance illustrator under commission remains with the creator unless explicit rights transfer occurs.

Copyright is broadly divided into two categories. One is "economic rights" (著作財産権), which encompasses a bundle of economic rights including reproduction rights, adaptation rights, public transmission rights, and exhibition rights. The other is "moral rights" (著作者人格権), consisting of three types: the right of disclosure, the right of attribution, and the right of integrity. Economic rights can be transferred or licensed to others, but moral rights are personal and cannot be transferred or waived.

The key point for freelance illustrators to understand in practice is that transfer of economic rights requires an explicit "assignment agreement." The mere facts of "receiving production compensation" or "delivering the work" do not transfer rights. However, in reality, many clients mistakenly believe that "since we paid, all rights have transferred to us." This gap in understanding is the fundamental cause of subsequent disputes.

Additionally, for works created by employees of corporations in the course of their duties, there is a "work made for hire" system (Article 15 of the Copyright Act) where the corporation becomes the author if certain requirements are met. However, external commissioning of freelancers generally does not meet the requirements for work made for hire, so the copyright of commissioned illustrations remains with the illustrator unless there is a special agreement.

The copyright protection period extends 70 years after the author's death (Article 51 of the Copyright Act). Understanding the significance of this long protection period is essential when carefully determining how rights should be handled.

This section analyzes structural risk factors created by the combination of industry practices and contract inadequacies.

The first factor is the practice of proceeding with work using only purchase orders and delivery notes. Especially in commissions from individuals and small businesses, production often begins with just an exchange of "please do this" and "understood," arriving at delivery without any agreement about copyright whatsoever. While it is easy to prove that rights remain with the illustrator even if the client later claims "I bought it so I can use it for anything," resolving such disputes takes time and emotional cost.

The second factor is the lack of awareness about the distinction between "copyright assignment" and "licensing." Copyright assignment means transferring the economic rights themselves to the other party. Licensing, on the other hand, means the rights holder retains their rights while permitting use under specific conditions. Contracts that confuse these two lead to divergent interpretations later, increasing litigation risk.

The third factor is that the "scope of secondary use" has expanded infinitely with the spread of SNS and digital content. A single illustration may be successively repurposed from website publication, SNS posts, printed materials, merchandise manufacturing, video content, and overseas distribution. There are actual cases where what was originally contracted as "one illustration for a website" ended up being used as product packaging worldwide years later.

The fourth factor is that compensation structures and the scope of rights are not linked. In the professional photography world, "rights management" — setting usage fees by purpose — is standard. However, in the illustration industry, there remains a strong misconception among clients that "one production fee covers all purposes." This practice continues to cause economic losses for illustrators.

The fifth factor is the absence of clear standards regarding modification and derivative works. When a client unilaterally changes colors, trims, or adds text to a commissioned illustration, this may constitute infringement of the author's moral right of integrity. However, many illustrators endure this without exercising their rights.

This section presents specific methods for setting rights by use case and achieving additional compensation.

Clear Definition of Usage Scope

In the initial consultation when accepting a commission, confirm the purpose, medium, period, and region of use in specific terms. It is important to understand all of the following items without omission:

Usage Confirmation Items:
・Medium (web / print / video / e-book, etc.)
・Specific usage location (company website / SNS / store POP / magazine advertising, etc.)
・Publication period (limited to 3 months / indefinite, etc.)
・Geographic scope (domestic only / worldwide)
・Estimated distribution / view count / display scale
・Commercial or non-commercial use
・Whether transfer, resale, or sublicensing is planned

Based on this information, it is appropriate to set a "licensing fee" separate from the initial production compensation.

Pricing Model by Use Case

Following the principle that broader usage scope means higher fees, categorize usage as follows:

[Base Compensation (Production Fee)]
・Per illustration: ¥30,000 and above
※Production scope: One web medium, domestic only, 1-year use

[Additional Licensing Fee Guidelines]
・SNS additional use: +¥5,000 and above
・Print materials (flyers, brochures): +¥15,000 and above
・Magazine advertising: +¥30,000 and above
・TV commercials / video advertising: +¥50,000 and above
・Merchandise manufacturing/sales: 5–10% royalty on sales
・Overseas use additional: +¥20,000 and above
・Period extension (per year): +¥10,000 and above
・Copyright assignment (full transfer): 3–5 times the production fee

When completely assigning copyright, compensation considering all future uses listed above is necessary. It is important to make clients understand that this is not simply an add-on to the production fee, but compensation for "relinquishing lifetime earnings."

Setting Conditions for Modification Permissions

While the right of integrity among moral rights cannot be transferred, in practice many contracts include a special provision "not to exercise the right of integrity." This provision should not be granted lightly.

When permitting modifications, limit conditions as follows:

Example Modification Permission Conditions:
・Permitted modifications: Background color changes, size trimming
・Pre-approval required modifications: Adding text, adding elements to characters
・Prohibited modifications: Conversion to sexual or violent content, compositing with other copyrighted works
・Use as AI training data: Prohibited without explicit permission

Regarding repurposing as AI training data, this has become a particular problem in recent years. Adding an explicit prohibition clause to contracts is strongly recommended.

This section presents contract structures and sample language that can be used in practice to prevent disputes before they occur.

Essential Clauses on Copyright

The following clauses must be included in illustration production contracts.

Clause clarifying rights ownership

(Copyright Ownership)
Article ○
1. The copyright (including rights stipulated in Articles 27 and 28 of the Copyright Act) in the deliverables produced under this agreement (hereinafter "the Illustration") belongs to Party B (Illustrator).

2. Party A (Client) may use the Illustration only within the following scope:
   ・Medium: [Enter specific medium name]
   ・Period: [Enter specific period]
   ・Territory: [Domestic only / Worldwide, etc.]
   ・Purpose: [Enter specific purpose]

3. In the event of use beyond the scope defined in the preceding paragraph, Party A must obtain prior written consent from Party B and pay a separate licensing fee.

Prohibition clause for modification and secondary use

(Prohibition of Modification, etc.)
Article ○
1. Party A shall not modify, adapt, edit, or process the Illustration without Party B's prior written consent.

2. Party A shall not use the Illustration as AI training data, for database construction, or for any other machine learning purposes.

3. Party A shall not sublicense the Illustration to third parties.

Clause linking payment and copyright

(Conditions for Copyright Activation)
Article ○
Until Party A pays the full compensation stipulated in this agreement, Party A shall have no right to use the Illustration. Upon completion of full payment, the usage rights defined in Article ○ shall be granted to Party A.

Responding When Copyright Assignment is Requested

Clients may request to "purchase all copyright." In such cases, always confirm and negotiate the following points:

1. Confirming scope of assignment: Whether it covers only economic rights, or also includes non-exercise of moral rights
2. Negotiating compensation: Presenting an appropriate price that accounts for projected future usage income (3–5 times the production fee is standard)
3. Securing portfolio rights: Retaining the right to display the work as a production achievement
4. Securing attribution credit: Maintaining display of the creator's name

Even when agreeing to complete copyright assignment, it is recommended to always retain the clause: "Party B retains the right to display the Illustration as evidence of their own work."

This section presents step-by-step response procedures when you discover your illustration is being used without permission.

Confirming Infringement and Preserving Evidence

First, calmly assess the situation and preserve evidence. Emotional actions will disadvantage subsequent negotiations and litigation.

Evidence Preservation Procedure:
1. Take screenshots (in a form showing date, time, and URL)
2. Save using web archive services (archive.org, etc.)
3. Prepare your own production data (PSD files, work logs showing the production process)
4. Organize delivery records and emails (proof of when and to whom delivery was made)
5. Detailed records of the infringement (usage medium, scale of display, whether commercial use)

Step-by-Step Response Procedures

[Step 1: Contact the Infringer (within 1 week of discovery)]
・Request cessation of use by email or registered letter
・Avoid emotional language; describe facts only
・Clearly state: "acknowledgment of copyright infringement facts," "deadline for cessation (7–14 days)," "request for response"

[Step 2: Report to Platform (implement simultaneously)]
・Report through "copyright infringement report forms" on SNS, video sites, EC sites
・More rapid content removal can be expected compared to legal procedures

[Step 3: Negotiation/Settlement (after infringer responds)]
・Request cessation of use + usage fees equivalent to past use
・Put agreed content in writing (settlement agreement)

[Step 4: Legal Action (if negotiations fail)]
・Consult an attorney or legal aid (copyright specialist attorney is preferable)
・Claim for damages (utilize damage amount presumption provisions in Article 114 of the Copyright Act)
・Application for injunction / filing of lawsuit

Preventive Measures

Ongoing measures to prevent infringement before it occurs are also important.

Regularly use Google's "reverse image search" or specialized tools (such as TinEye) to check whether your works are being used without permission. For works with high commercial value, periodic checks two to three times per year are recommended.

Also, embedding "digital watermarks (steganography)" in work at the time of delivery in an inconspicuous form makes it easier to assert rights later.

When publishing work on SNS, adding the credit "©2026 [Name] All Rights Reserved" provides explicit copyright notice and a deterrent effect against unauthorized use. In a climate of growing concern about copyright infringement, creators are expected to actively utilize self-protection measures.
