The presiding judge in Morioka District Court said the 24-year-old Umeta attacked them because he was frustrated over not being able to find a job, Kyodo news service reported.
Established in 2005, AKB48 has a rotating cast of more than 90 young women, and affiliates across the country and in Indonesia, China and Taiwan. Its members are dubbed "idols you can meet" because of their fan events, at which those who buy special CDs can shake hands and chat briefly with their favorite member.

As soon as the handshaking event started in May, Umeta took a foldable saw from his jacket, approached the women and attacked them. They were cut on their hands and face, and hospitalized overnight. The singers -- Anna Iriyama and Rina Kawaei -- have since returned to performing with the group.
