First appearing on the anonymous Japanese forum 2channel in 2005, the story spread rapidly across the internet, inspiring countless discussions, videos, novels, and horror adaptations.

We also separate verified history from internet fiction, exploring how one anonymous post evolved into one of Japan's most famous cursed-object legends.
