Japanese Right-Wing Groups Use AI to Falsify Historical Videos
China's State Security Ministry reported that Japanese right-wing groups are using AI to mass-produce false historical content denying the Nanjing Massacre and distorting records of Japan's invasion of China. The groups reportedly recruit people through crowdsourcing platforms like CrowdWorks to generate videos with simple AI prompts, potentially contaminating China's large language model training data.
What happened
Chinese State Security Ministry stated on July 26, 2026 that Japanese right-wing groups are using crowdsourcing platforms including CrowdWorks to recruit people for payment to create AI-generated videos falsely denying the Nanjing Massacre and distorting Japan's invasion of China.
According to the ministry, recruiters provide operation guides to workers, who input simple instructions into AI software to generate the false videos within minutes. The ministry cited reporting by Japan's Asahi Shimbun newspaper.
Reported impact
The ministry warned that the false videos spread rapidly through online platforms and could contaminate China's large language model training data, potentially causing AI systems to develop bias toward Japanese right-wing historical narratives when answering historical questions.
The ministry stated the content risks misleading young people whose historical knowledge is incomplete, and could dissolve the collective memory and consensus formed during China's anti-Japanese war.
Index analysis
The ministry cited Japanese government budget data showing that since 2015, Japan has invested over 56 billion yen in 'overseas strategic information dissemination,' including efforts to distort historical awareness and minimize Japan's wartime responsibility.
