Miyuki Asou was a gravure idol who crossed over to AV and the harsh (mostly online) criticism she received after making that transition was rumored to be the reason she took her own life on March 18, 2008. She was found dead in her bathroom after inhaling the poisonous gas from the household chemicals she had mixed together. Known as "detergent suicide," it's a fairly popular method of ending one's own life in Japan. She was 22.
