Japanese “One Piece” singer Maki Otsuki’s concert in Shanghai was abruptly cut short on Friday night, as rising diplomatic tensions between China and Japan spilled directly onto the stage. Fans were left stunned when the lights went out mid-song and staff moved in, leading Otsuki offstage without explanation. Her management later confirmed she had been forced to stop “due to unavoidable circumstances” on Friday “even though she was in the middle of performing”, despite being only partway through her set. A video circulating online shows the exact moment the performance was halted — music cutting out, stage lights shutting down, and visibly confused fans calling out as Otsuki is calmly escorted away by staff. Otsuki, best known for singing the first ending theme of the hit anime One Piece, had been scheduled to perform for two days at the Bandai Namco Festival 2025 in Shanghai. But her interrupted performance quickly became the latest cultural casualty in a growing list of cancellations affecting exchanges between Asia’s two largest economies. The chill in relations follows remarks earlier this month from Japanese prime minister Sanae Takaichi, suggesting Japan could intervene militarily if Taiwan were attacked. Beijing, which claims Taiwan as its territory, reacted with fury — summoning Japan’s ambassador and issuing a travel warning urging Chinese citizens to avoid Japan. The fallout has rippled into the entertainment world. This isn’t an isolated incident. Other Japanese artists—including pop icon Ayumi Hamasaki and acclaimed jazz pianist Hiromi Uehara—have had their China shows scrapped in recent days.
