Japanese vlogger Hayato Kato's 1.9 million followers are used to his funny clips about exploring China, where he has been living for several years.
But on 26 July he surprised them with a sombre one.
"I just watched a movie about the Nanjing Massacre," he said, referring to the Japanese army's six-week rampage through Nanjing in late 1937, which, by some estimates, killed more than 300,000 civilians and Chinese soldiers. Around 20,000 women were reportedly raped.
Dead To Rights, or Nanjing Photo Studio, is a star-studded tale about a group of civilians who hide from Japanese troops in a photo studio. Already a box office hit, it is the first of a wave of Chinese movies about the horrors of Japanese occupation that are being released to mark the 80th anniversary of the end of World War Two. But a sense of unfinished history - often amplified by Beijing – persists, fuelling both memory and anger.
Speaking in Chinese on Douyin, China's domestic version of TikTok, Kato recounted scenes from the film: "People were lined up along the river and then the shootings began… A baby, the same age as my daughter, was crying in her mother's arms. A Japanese soldier rushed forward, grabbed her, and smashed her into the ground."
