China-linked accounts spread disinformation in Japanese election
Approximately 400 accounts with suspected Chinese origins reportedly spread disinformation on social media during Japan's February 2026 election, using AI-generated images and falsified information to attack Prime Minister Takaichi Sanae and her party. Japanese media and analysts characterized the campaign as an evolved form of cognitive warfare targeting democratic processes.
What happened
During Japan's February 2026 House of Representatives election, approximately 400 accounts with suspected Chinese origins spread disinformation on social platform X, concentrating attacks on Prime Minister Takaichi Sanae and the ruling Liberal Democratic Party.
The campaign used AI-generated images and fluent Japanese text to amplify contentious topics including fabricated allegations linking Takaichi to a religious organization, doctored photographs with shadow effects and exaggerated contrasts, and falsified family background claims describing her grandfather as a Japanese military officer involved in invasions. Content first circulated on Taiwanese social media before reflowing to Japanese platforms.
Reported impact
The disinformation campaign targeted Takaichi's political image and sought to influence voter perception during the election campaign.
Index analysis
According to Japanese media reporting, the campaign represented a new evolution in cognitive warfare tactics, combining AI-generated imagery with coordinated account activity. The short election cycle—approximately 16 days from announcement to voting—reportedly limited the scope of interference possible through account network building and targeted messaging.
Governance controls
Following the incident, Prime Minister Takaichi announced in a February 20 policy speech plans to elevate the Cabinet Intelligence and Research Office to a 'National Intelligence Agency' and establish a 'National Intelligence Conference' directly under the Prime Minister, partly in response to the revealed Chinese account activity.
