Terms of Service

日本語

Last updated: September 11, 2026

These Terms of Service ("Terms") set out the conditions for using MeltChat (the "Service") provided by NK Co., Ltd. ("we", "us", or "the Company"). By agreeing to these Terms, users ("you" or "User") may use the Service.

Article 1 (Application)

These Terms apply to all relationships between us and Users arising in connection with the use of the Service. Individual rules, guidelines, and notices that we post on the Service form part of these Terms. If these Terms conflict with any individual rules, the individual rules prevail.

Article 2 (Age Verification and Eligibility)

The Service contains adult-oriented images, conversations, and expressions, and may not be used by persons under 18. By using the Service, you represent and warrant that you are 18 years of age or older. At registration we display an age-verification screen and confirm, based on your self-declaration, that you are 18 or older. Using the Service through a false age declaration violates these Terms, and we are not responsible for any disadvantage arising from such violation.

Article 3 (Account Management)

You must manage your account information appropriately at your own responsibility and must not allow third parties to use it, or transfer, lend, or share it. Except in cases of our intent or negligence, we are not responsible for damage arising from unauthorized use of an account by a third party.

Article 4 (Prohibited Conduct)

In using the Service, you must not engage in any of the following:

  • acts that violate laws or public order and morals;
  • criminal acts, acts that promote crime, inducement of suicide or self-harm, or acts related to the handling of illegal drugs;
  • creating, transmitting, sharing, or attempting to generate child pornography, expressions that sexualize minors, or sexual or exploitative content involving persons resembling minors, whether real or fictional;
  • infringing the intellectual property, portrait, publicity, privacy, reputation, or credit of us, other Users, or third parties;
  • discrimination, harassment, stalking, hate speech, or impersonating others;
  • placing an excessive load on the networks or systems of the Service;
  • unauthorized access, reverse engineering, decompilation, or otherwise attempting to analyze or tamper with the system;
  • mass access or data acquisition by automated means (crawlers, scrapers, etc.);
  • allowing minors to use the Service, or impersonating another person;
  • sending spam, phishing, malware, or other harmful content to third parties through the Service; or
  • any other act that we reasonably determine to be inappropriate.

Article 5 (Rights in and License to User Content)

Copyright in the works, characters, text, images, audio, and similar materials that you create or submit on the Service ("User Content") belongs to you or the rightful owner.

However, you grant us a free, non-exclusive license to use such User Content (including reproduction, public transmission, adaptation, transmission to AI inference providers, and creation of derivative works) to the extent necessary to provide, operate, maintain, improve, promote, research and develop the Service, and to exercise rights under these Terms. This license is valid in all countries and regions where we provide the Service and includes the right to sublicense.

We do not use individual User Content as training data for AI models that we or third parties make publicly available. For the use of anonymized or aggregated data, please refer to our Privacy Policy.

You represent and warrant that you have the authority to submit the User Content to the Service (including obtaining necessary rights clearances and third-party consents).

Article 6 (Handling of AI-Generated Content)

The Service uses AI to generate character responses, text, images, audio, and similar outputs. AI-generated outputs are handled as follows:

  • AI-generated outputs are produced based on your input, the parameters you select, and the output of the AI models we use; we make no warranty as to their accuracy, legality, usefulness, or non-infringement.
  • You are solely responsible for your input and the outputs generated through AI, and must use them in compliance with these Terms and applicable laws.
  • If AI-generated output infringes the rights of a third party, we may remove the content and, where necessary, take measures such as suspending the poster's account.
  • We provide AI features in accordance with the terms of the AI inference providers. You must not use the Service for purposes that violate those providers' terms.

Article 7 (Content Moderation)

To ensure the safety of Users and third parties, we may review and respond to content on the Service by the following means:

  • receiving and responding to reports from Users;
  • using automated filtering and detection mechanisms;
  • review by our staff where we deem it necessary; and
  • removing violating content, restricting its display, and limiting or suspending accounts.

We are not obligated to constantly monitor all content on the Service, and the presence or absence of review or action by us does not signify our agreement with or endorsement of the content.

Article 8 (Charges, Points, and Refunds)

The sale prices, purchase conditions, consumption conditions, and timing of provision of paid items (such as points) on the Service follow the purchase screen and the "Notation Based on the Act on Specified Commercial Transactions."

  • Points may be used only within the Service. Points granted through purchase may be used for 180 days from the date of grant (the date points are credited to the User's account upon completion of the purchase procedure); any unused purchased Points that remain after such period shall expire. Bonus Points granted through campaigns or promotions may be used only for the separately displayed period from the date of grant; any unused bonus Points that remain after such period shall expire. Expiration and other conditions of use are also shown on the purchase screen and elsewhere in the Service.
  • Due to the nature of digital content, we do not accept returns or refunds for your own convenience after purchase is completed. However, we may provide refunds under applicable law, for example where goods were not delivered due to a fault attributable to us. For details, see our Return / Refund Policy.
  • If we terminate the Service, we will give prior notice and handle unused points appropriately in accordance with applicable law.

For payment processing purposes, payments for the Services may be processed by the following payment processing entity: Lynshine Company Limited, Avon House Avonmore Road, Kensington, W14 8TS, London, United Kingdom (Company number 16722557).

Article 9 (Reporting Infringement)

If you or a third party believe that content published on the Service infringes your copyright, portrait rights, privacy, reputation, or similar rights, you may report it to support@meltchat.jp. Copyright notices are handled under Article 16, reports of illegal or Terms-violating content under Article 17, and removal requests by depicted persons under Article 18. We will take reasonable measures such as removal or prevention of transmission in accordance with applicable law and the framework of the Provider Liability Limitation Act, and will handle requests for disclosure of sender information in accordance with law.

Article 10 (Suspension of the Service)

We may suspend or interrupt all or part of the Service without prior notice due to system maintenance, failures, natural disasters, or other unavoidable circumstances. We are responsible for damage caused thereby to Users or third parties only to the extent provided by these Terms and applicable law.

Article 11 (Usage Restrictions and Deregistration)

If you violate any provision of these Terms, or if we reasonably determine that continued use of the Service is inappropriate, we may restrict your use of the Service, remove content, or delete your account. Except in cases of urgency or serious violation, we will endeavor to provide you a reasonable opportunity to cure.

Article 12 (Disclaimer and Limitation of Liability)

We make no warranty, express or implied, that the Service is fit for your particular purpose, has the functions, accuracy, or usefulness you expect, will be free from defects, errors, or interruptions, or that AI-generated output will not infringe the rights of third parties.

Where damage arises to a User due to a cause attributable to us, we are liable for such damage; however, except in cases of our intent or gross negligence, our liability is limited to the total amount you paid us for the Service in the 12 months preceding the occurrence of the damage.

The provisions of this Article do not apply to the extent they violate Articles 8, 8-2, and 9 of the Consumer Contract Act or other mandatory laws, and shall be interpreted in accordance with applicable law within that scope.

In no event are we liable for incidental, indirect, special, consequential, or punitive damages, except where such exclusion is not permitted by law.

Article 13 (Changes to the Terms)

We may change these Terms in accordance with the requirements of Article 548-4 of the Civil Code where we reasonably determine it necessary due to amendments to applicable law, changes to the Service, or other reasons.

When we change these Terms, we will make the amended content and effective date known by posting on the Service or by other appropriate means. For changes that materially and adversely affect Users, we will give notice at least 30 days before the effective date; other changes will not take effect until 7 days after posting. This does not apply to changes that correspond to new features of the Service or that must be made immediately due to law.

Article 14 (Governing Law and Jurisdiction)

To comply with applicable regulatory requirements for different customer groups, these Terms may be subject to different governing laws. UK-based customers are governed by the laws of the United Kingdom, while customers in the APAC region are governed by the laws of Japan.

For customers in the APAC region, these Terms are governed by the laws of Japan, and any dispute relating to the Service or these Terms shall be submitted to the Tokyo Summary Court or the Tokyo District Court, depending on the amount in dispute, as the exclusive agreed court of first instance. Where the User is a consumer under applicable law, this Article does not prevent the User from bringing proceedings before the court that has jurisdiction over the User's place of residence.

For UK-based customers, these Terms are governed by the laws of the United Kingdom, and the courts of the United Kingdom shall have jurisdiction. Mandatory consumer-protection laws of each jurisdiction apply with priority to the extent they are applicable.

Article 15 (18 U.S.C. §2257 Statement)

All visual depictions displayed on MeltChat are either (a) computer-generated or AI-generated and do not depict any actual human being, or (b) do not portray conduct subject to the record-keeping requirements of 18 U.S.C. §2257 and 28 C.F.R. Part 75. Accordingly, the content on this Service is exempt from those requirements, and we do not create or maintain age-verification records for actual performers.

The Custodian of Records for this statement, and the contact details for inquiries, are as follows. No account is required.

  • Name: Kenji Kawakami
  • Company: NK Co., Ltd.
  • Address: N&E BLD. 7F, 1-12-4 Ginza, Chuo-ku, Tokyo 104-0061, Japan
  • Email: support@meltchat.jp
  • Phone: 050-1720-6445

Users are prohibited from uploading, generating, or distributing any visual depiction of an actual, identifiable person engaged in sexually explicit conduct. If such content is discovered or reported, we will remove it and take other measures under Article 17 and, where required by law, report it to the relevant authorities. Questions regarding this statement may be directed to the contacts above.

Article 16 (DMCA Notice and Takedown Policy)

We respect the intellectual property rights of others and respond to notices of alleged copyright infringement that comply with the Digital Millennium Copyright Act (DMCA) (17 U.S.C. §512). Notices of trademark or other intellectual-property infringement may also be submitted through this contact point and will be reviewed under Article 17.

Our Designated Agent is as follows. Notices may be submitted by email or by postal mail. No account is required.

  • Name: Kenji Kawakami
  • Company: NK Co., Ltd.
  • Postal address: N&E BLD. 7F, 1-12-4 Ginza, Chuo-ku, Tokyo 104-0061, Japan
  • Email: support@meltchat.jp
  • Phone: 050-1720-6445

If you believe that content on MeltChat infringes your copyright, please send a written notice to the Designated Agent containing:

  • your physical or electronic signature;
  • identification of the copyrighted work claimed to be infringed;
  • identification of the infringing material and information reasonably sufficient to locate it (e.g., a URL);
  • your contact information (address, telephone number, and email);
  • a statement that you have a good-faith belief that the use is not authorized by the copyright owner, its agent, or the law; and
  • a statement, under penalty of perjury, that the information is accurate and that you are the copyright owner or authorized to act on its behalf.

The Designated Agent will check whether a notice meets the requirements of this Article. If it is incomplete, we may ask the complainant to supplement it. A valid notice will be reviewed within 5 business days of receipt and, where infringement is found, we will remove or disable access to the material and make a reasonable effort to notify the user who posted it. Suspected child sexual exploitation and other emergencies are acted on immediately and, where required by law, reported to the relevant authorities.

The user who posted the material may submit a counter-notification to the Designated Agent containing:

  • a physical or electronic signature;
  • identification of the material that was removed or to which access was disabled, and the location at which it appeared before removal (e.g., a URL);
  • a statement under penalty of perjury that the user has a good-faith belief that the material was removed or disabled as a result of mistake or misidentification;
  • the user's name, address, and telephone number, and a statement that the user consents to the jurisdiction of the Federal District Court for the judicial district in which the address is located (or, if the user is outside the United States, to the jurisdiction of any judicial district in which we may be found); and
  • a statement that the user will accept service of process from the original complainant.

Upon receipt of a valid counter-notification, we will forward a copy to the original complainant. Unless we first receive notice that the complainant has filed an action seeking a court order, we may restore the material no sooner than 10 business days and no later than 14 business days after receipt of the counter-notification.

We will terminate, in appropriate circumstances, the accounts of repeat infringers. We will notify the complainant and (where a counter-notification is filed) the posting user of the outcome and of the measures taken, such as removal, no action, a request for more information, or restoration.

Article 17 (Complaints Process)

Any person may report content that they believe is illegal or otherwise violates our Standards or these Terms, whether or not they have an account. Copyright notices are governed by Article 16, and removal requests by depicted persons by Article 18, in preference to this Article.

Complaints may be submitted as follows:

  • Email: support@meltchat.jp (preferred; no account required; please use the subject line "Content report")
  • Phone: 050-1720-6445
  • the member support chat on the Contact page
  • in-service reporting functions (including comment reports and chat-image reports, where shown on screen)

Please include the following information to the extent reasonably available:

  • the URL of the content, or other information reasonably sufficient to locate it;
  • a description of the issue and why you believe it is illegal or violates our Terms or Standards;
  • your name and email address for notification of the outcome; and
  • any supporting materials you have.

We will endeavor to acknowledge receipt at the contact details provided. Support or compliance staff will examine the content, the complaint, and related accounts. We may request additional information from the complainant. Each complaint will be reviewed and resolved within 5 business days of receipt, based on the information then available. Business days exclude Saturdays, Sundays, and Japanese public holidays. Suspected child sexual exploitation and other emergencies are acted on immediately, without waiting for this deadline.

We determine whether a violation of law, these Terms, or our content Standards has occurred, and may take one or more of the following measures:

  • leave the content in place if no violation is found;
  • remove or restrict the content;
  • warn, restrict, suspend, or delete the responsible account;
  • take reasonable steps to prevent the same content from being reposted; and
  • where required by law, report to the relevant authorities and preserve evidence.

The final outcome is communicated to the contact details provided with the complaint (usually by email). The notice will state that the review is complete, whether the complaint was upheld or declined, and a summary of the measures taken. We may omit details that would compromise personal data protection or an investigation. If you disagree with the outcome, you may request a further review through the same channel within 14 days of the notice. That further review will also be completed within 5 business days of receipt, and we will notify you of the result.

Article 18 (Right of Depicted Persons to Request Removal)

Any person who appears, or believes they appear, in a video, image, or other content on MeltChat (including an authorized representative) may request its removal. This right applies regardless of whether the person previously consented to the content. Although content on the Service is in principle computer-generated or AI-generated, a claim that an actual person is depicted is reviewed under this Article.

Submit the request through the same channels as Article 17, and state clearly that it is a removal request by a depicted person. No account is required. Include the URL or location of the content, a description of where the person appears, a statement that you are that person or an authorized representative, and contact details for notification. We may request reasonably sufficient additional information to verify identity.

We will review the request within 5 business days of receipt. Where the claim is credible, we may restrict display of the content pending verification. If identity is verified, we will remove the content and may take Article 17 measures against the posting account. If we cannot verify the claim, we may request more information and, if that remains insufficient, decline the request and notify you of a summary of the reasons.

If a request is initially declined, you may appeal by submitting additional explanation or materials through the same channel within 14 days of the notice. Where practicable, a different reviewer will conduct the further review. We will make a final determination within 5 business days of receiving the appeal and will notify the requester of the outcome (removal or decline).
