Japanese manga artist Ryūju Ryou's predicted doomsday earthquake on July 5 did not occur, leading to dissatisfaction and anger from numerous Japanese netizens, although some argued that the lack of an event was a good thing.

In her work What I See in the Future, Ryou forecasted a catastrophic earthquake at 4:18 AM on July 5 (3:18 AM Taiwan time), which attracted nearly 250,000 viewers to a YouTube live stream monitoring the earthquake in Japan. However, the prediction did not materialize, and Ryou explained that the text on the book jacket was written by her editor, leading many on the Japanese PTT forum 5ch to dismiss her claims and criticize her fiercely, with some even calling her a fraud and witch.

According to reports, before the 'doomsday controversy,' Ryou expressed in a magazine interview that she had difficulty addressing this issue, mentioning concerns that the publisher's editor might be defamed. She admitted that the text in the 'complete edition' was not her writing, causing her to feel more like a reader than an author. As news spread to the 5ch forum, the overwhelming majority of users rejected her explanation, with comments such as 'Your afterword stated similarly, could you say that was also solely due to the editor's hand?' and 'Why can't she be arrested for spreading false rumors?'

However, some users expressed relief that nothing happened, stating, 'At least it didn't happen, that’s a good thing,' asserting that those who believe such predictions are likely gullible.
