With the hangings of six former members of the Aum Shinrikyo doomsday cult Thursday, Yoko Kamikawa became the justice minister who has ordered the most executions, 16, since Japan lifted its 40-month moratorium on the death penalty in 1993.

Thirteen of the 16 executed individuals were former members of the doomsday cult. Aum founder Shoko Asahara, who masterminded the 1995 sarin attack on the Tokyo subway system and other heinous crimes, and six others were hanged earlier this month.

Kamikawa ordered one execution during her yearlong stint as justice minister from October 2014. Since resuming the position in August last year, she has ordered two executions in December and 13 this month. All of the orders were under the administration of Prime Minister Shinzo Abe.
