One Piece Publisher’s Legal Win Complicated by U.S. Court Ruling
A recent ruling by a California federal court has thrown a wrench into Shueisha’s efforts to combat manga piracy, specifically concerning the takedown of the massive piracy site Mangajikan.com. While Shueisha initially secured a victory in obtaining the operator’s identity through a DMCA subpoena, the court has now restricted how that information can be used, limiting its application to U.S.-based copyright claims.
The Mangajikan Case: A Timeline
In 2025, Shueisha, the publisher of popular manga like One Piece and Jujutsu Kaisen, targeted Mangajikan and its related domain, alammanga.com, with a DMCA subpoena served to Cloudflare. The sites were voluntarily taken down shortly after. A subsequent court order in October 2025 compelled Cloudflare to disclose the operator’s personal details. Still, this victory has been tempered by the February 2, 2026, ruling.
Data Usage Restricted to the U.S.
The core of the dispute centered on whether Shueisha could utilize the unmasked operator’s identity for copyright lawsuits in foreign jurisdictions, such as Japan. Shueisha argued they lacked knowledge of the operator’s physical location when the subpoena was initially requested. Judge Hixson disagreed, citing that the original sworn declaration explicitly limited the data’s leverage to protecting rights under Title 17 of the United States Code – effectively restricting its use to U.S. Copyright claims.
Implications for International Copyright Enforcement
This ruling poses a significant challenge for Shueisha. If the operator resides outside the U.S., pursuing legal action would necessitate adhering to the copyright laws of their home country. The publisher is now blocked from leveraging the data obtained through the DMCA subpoena to initiate litigation abroad.
Shueisha’s attempt to circumvent this limitation by filing a U.S. Copyright lawsuit – thereby making the information publicly available – was rejected by Judge Hixson. The court emphasized that rightsholders cannot alter their initial legal attestation to bypass DMCA restrictions.
Operator’s Privacy, Partially Protected
While the operator lost the battle against disclosing their identity, they did avoid complete exposure. Shueisha is permitted to publicly identify the operator by name in U.S. Court filings, but sensitive personal information like phone numbers and email addresses remains protected.
The publisher can use the information for settlement negotiations or to collaborate with U.S. Law enforcement. Cloudflare is now obligated to provide the operator’s identity to Shueisha’s legal team, who must decide whether to pursue a U.S. Lawsuit or risk the data being destroyed when the statute of limitations expires.
Mangajikan was a significant player in manga piracy, attracting 185 million visitors in May 2025 and ranking among the most visited websites in Japan before its closure.
