March 29 (Asia Today) — China intensified an online influence campaign targeting Japan during the country’s February general election, sharply increasing English-language messaging aimed at shaping international opinion, according to a joint analysis cited by Japanese media.

The Yomiuri Shimbun reported Sunday that the findings were based on a joint study with AI firm Sakana AI, which examined social media posts, including on X, from Jan. 19 through mid-February.

The analysis tracked what researchers described as the “flow of narratives” in China-linked criticism of Japan. It found that English-language posts outnumbered Japanese-language content by as much as four to one, indicating a strategic shift toward influencing global audiences rather than domestic Japanese opinion.

The surge followed remarks by Japanese Prime Minister Sanae Takaichi in November, when she described a potential Taiwan contingency as a “crisis threatening Japan’s existence.” After several days of relative silence, China-linked accounts escalated criticism of Japan.

The volume of such posts rose steadily during the election period. Researchers estimated roughly 1,400 posts on Jan. 19, increasing to about 1,700 by Jan. 23 and 1,800 by Jan. 27. On Feb. 8, the day of voting, the number surged to around 4,000, though still below levels seen during a larger campaign in November.

The messaging themes also shifted. Earlier narratives focused on criticizing Japan’s leadership and accusing Tokyo of interfering in Taiwan-related issues. During the election, however, posts increasingly framed Japan in terms of “militarization,” “revival of militarism,” and economic decline. As voting approached, criticism of political leadership again became more prominent.

A Japanese government official said the messaging may have been designed to influence voter behavior through pressure or intimidation.

Separate analysis of posts from November through January showed a sharp rise in English-language output from accounts linked to the Chinese Communist Party. During a peak period in mid-November, English-language criticism reached roughly four times the volume of Japanese posts. In December, about 560 of roughly 900 posts were in English, and in January, more than half of approximately 300 posts were written in English.

Officials in Japan suggested the shift reflects a strategic recalibration. With the Takaichi administration maintaining relatively strong approval ratings despite earlier criticism, Chinese efforts may have pivoted toward shaping international narratives rather than domestic opinion.

A Chinese official was quoted as saying the campaign would continue to apply “tactical pressure” on Takaichi while seeking to prevent countries from aligning with Japan.

The report concluded that China’s social media operations during the election represented a coordinated effort to influence both domestic and global perceptions by leveraging political and security narratives.
