A written notification of claimed infringement should include substantially all of the following:

• a physical or electronic signature of the copyright owner or a person authorized to act for the owner;
• identification of the copyrighted work, or a representative list when one notice covers multiple works at one online location;
• identification of the material or activity claimed to be infringing and information reasonably sufficient for Tsuiseki to locate it;
• your name, mailing address, telephone number, and, when available, email address;
• a statement that you have a good-faith belief that the complained-of use is not authorized by the copyright owner, its agent, or the law;
• a statement that the notice is accurate and, under penalty of perjury, that you are authorized to act for the owner of the allegedly infringed exclusive right.

For faster review, identify the exact Tsuiseki page, title, provider, and external destination involved, and state the correction or removal requested.

Do not send chapter images, video files, stream manifests, access tokens, passwords, or unnecessary identity documents. Exact URLs and a clear description are normally sufficient for initial review.

A person whose material was removed or disabled because of a copyright notice may send a written counter-notice containing substantially all of the following:

• a physical or electronic signature;
• identification of the material removed or disabled and the location where it appeared before removal or disablement;
• a statement under penalty of perjury that the sender has a good-faith belief the material was removed or disabled because of mistake or misidentification;
• the sender's name, address, and telephone number;
• consent to the jurisdiction of the applicable United States Federal District Court, including any judicial district where the service provider may be found when the sender is outside the United States;
• a statement that the sender will accept service of process from the person who submitted the original notice or that person's agent.

Where the statutory counter-notice process applies, Tsuiseki may restore affected material no fewer than 10 and no more than 14 business days after receiving a compliant counter-notice, unless the original complainant reports that a court action seeking restraint has been filed.

Tsuiseki may acknowledge receipt, request missing information, preserve relevant records, disable access expeditiously where appropriate, notify an affected user, provide a counter-notice to the original complainant where required, and apply its repeat-infringer policy.

Registration of a designated agent does not decide whether a claim is valid and does not require Tsuiseki to restore a provider or destination that remains disabled for separate safety, reliability, policy, or legal reasons.
