Prosecutors sought the death penalty for a former leader of the Japanese doomsday cult accused of a nerve gas attack in a Tokyo subway that killed 12 people and sickened thousands.
According to prosecutors, Yoshihiro Inoue's responsibility as a confidant of Aum Shinri Kyo guru Shoko Asahara and a direct participant in the 1995 attack was particularly significant, said a court spokesman.
Asahara is on trial for masterminding the sarin attack as well as for ordering the murder of an anti-cult lawyer and his family.
Inoue had admitted to all 10 charges of murder and other crimes and expressed remorse to the families of the victims, said Tomidokoro. Sentencing is expected by next spring, he said.
Inoue was the last of five cultists directly involved in the attack to face trial. Prosecutors have demanded death for four of the five.
Nine other cult members have been indicted as accomplices in the gassing.
Some victims remain in serious condition from the subway poisoning. Many more complain of chronic headaches, dizziness, irregular breathing or nausea.
