The Japanese government is moving to use artificial intelligence to translate manga more quickly and to identify pirate sites, a bid to curb piracy and support licensing and localization. The Agency for Cultural Affairs will back AI-driven translation initiatives and anti-piracy tooling, according to Nikkei Asia.
Piracy costs are staggering: illegal online distribution is estimated at 8.5 trillion yen annually, a figure that underscores the scale of the challenge for publishers. Only about 10 percent of manga published each year is translated into English, with many titles untranslated in other languages, underscoring a large untapped overseas market.
Private developers have built manga-focused AI tools to speed translation, including Mantra, a University of Tokyo startup-backed system that publishers Shogakukan and Shueisha back. Mantra can translate 18 languages and handles around 200,000 pages per month, translating text on the fly and automatically resizing speech bubbles when text is larger than the bubble. The company notes that AI reduces simple localization tasks, while humans remain essential for fine tuning and cultural nuance.
The government plans to fund translator training with AI, offering subsidies of 100 million yen per project, with applications open through March 21. The program will train translators in techniques and how to leverage AI, spanning industry groups, universities, and vocational schools, and private providers are already rolling out tools to assist translators in techniques and AI usage.
The Agency for Cultural Affairs also aims to deploy AI to detect pirate sites by the next fiscal year, moving beyond labor-intensive manual monitoring. A forthcoming system would automate takedown requests and issue warnings to site operators as part of enforcing copyright.
Only about 10 percent of manga published each year is translated into English, leaving significant overseas potential on the table, and officials have set a long-term goal to lift overseas sales to 20 trillion yen by 2033. In 2023, overseas sales reached about 5.8 trillion yen, illustrating the scale of the opportunity. Observers have noted that audiences have seen growth in anime alongside rising use of AI, signaling a broader shift in how content is produced, translated, and distributed.
The policy path will likely bring both opportunities and growing pains, with fans and creators watching translation quality, localization choices, and the balance between accessibility and copyright protection as AI tools mature.
