The abrupt cancellations of several Japanese music events in Shanghai - one of them midway through a song - have sparked criticism among fans, with some calling the moves "rude" and "extreme".
Maki Otsuki was halfway through the theme of hit anime One Piece on Friday when the lights and music went off, after which she was rushed off stage by two crew members.
On Saturday, pop star Ayumi Hamasaki performed to an empty 14,000-seat stadium after organisers axed her concert in Shanghai, citing "force majeure".
This spate of cancellations come as diplomatic tensions between Beijing and Tokyo fester over Japanese Prime Minister Sanae Takaichi's remarks on Taiwan.
Takaichi, known to be a vocal critic of China and its activities in the region, suggested last month that Tokyo could take military action if Beijing attacked Taiwan.
