Sachiko Eto, 65, became a "self-professed God" in the 1990's according to IB Times
. She acquired a cult following that believed in her powers to drive out demons during bizarre exorcism ceremonies involving Taiko drum sticks.
In 2005 Eto was sentenced to death when she was convicted of beating six cult followers to death and hiding their bodies in her home.
reported Eto's lawyers argued diminished responsibility due to mental problems. At her trial Eto claimed
"I did it as part of a religious service. I never thought they were going to die."
Her daughter and another cult member, Yutaka Nemoto, Eto's lover, were sentenced to life imprisonment after being convicted of acting as Eto's accomplices.
In addition to hanging Eto, Japan also hanged Yukinori Matsuda on Thursday. The Independent
