The Osaka prefectural assembly on Friday passed an ordinance which will go into effect from Oct 1.
Those convicted of sex crimes involving minors will be required to register their contact details with the authorities for up to five years following their release from prison. Failure to do so will incur a penalty of 50,000 yen, TBS reported.
Members of the main political parties voted in favor of the regulation, with the exception of the Japan Communist Party.
The Osaka government says the ordinance is aimed at supporting ex-convicts’ reintegration into society, and to help reduce the number of sex crimes against children, including the production of pornography involving minors.
