might disturb privacy and the adaptation to society" of former sex offenders, Noono told a news conference, responding to calls that both the public and police should have such information.
The ministry agreed Thursday to provide the National Police Agency with such information after former sex criminals are released from prison. The measure will hopefully prevent repeat offenses.
The ministry said it would provide such information to the NPA on condition that it not be released to third parties.
The move follows the arrest of a man in the kidnap-murder of an elementary school girl in Nara Prefecture in November. He has a record of sex offenses.
The NPA subsequently asked the government to establish a system to keep track of freed sex offenders.
"We must put an end to tragedies similar to the Nara case," Noono said. "We will continue discussions with the NPA."
