Naoko Kikuchi was nabbed in Kanagawa Prefecture Sunday after 17 years on the run and was turned over to Tokyo police to face murder and attempted murder charges.
Kikuchi allegedly s a member of the Aum Shinrikyo cult, which was blamed for the release of deadly sarin gas inside the Tokyo subway system, causing 13 deaths and around 50 injuries, the report said.
Kikuchi was specifically accused of helping make the gas.
Kyodo said Kikuchi was tracked down at a home in Sagamihara with the help of a tip from a citizen who said the resident looked like the fugitive cultist.
Kikuchi allegedly was one of three cult members who went underground after the spectacular subway attack. The only one of the trio still at large is 54-year-old Katsuya Takahashi.
