Check out our Patreon!On this episode of From One To Wicked, we dive into the horrifying crimes of Takahiro Shiraishi — who we dubbed the Cat Litter Killer. Known in the headlines as Japan’s “Twitter Killer,” Shiraishi lured vulnerable souls online with promises of shared suicide, only to betray them in the most brutal way imaginable. Between August and October 2017, he murdered nine people — mostly young women, some just teenagers — inside a tiny apartment that would be forever branded Japan’s “House of Horrors.”We trace how this seemingly quiet kid from Zama transformed into a manipulative predator, using hashtags and DMs to find his victims, sedate them, assault them, and dismember their bodies — hiding the remains in coolers packed with cat litter to mask the stench of death. From his troubled family life and shady work in Tokyo’s red-light district to his chilling confessions and final execution in 2025, we unpack every twisted detail of a case that shocked Japan, changed Twitter’s rules, and reignited debate over the death penalty.Press play — but be warned: this one is truly wicked.
