Tokyo's Suginami Ward filed a 44.7 million yen damages suit Tuesday against the central and Tokyo Metropolitan governments for not accepting partial data on residents for the national resident registry network, which was launched last August.

The suit, filed with the Tokyo District Court, arises from a decision by the ward to allow its residents to decide if they wanted their personal data entered in the national network, known as Juki Net.

According to the petition, the ward decided to phase in its participation in the network by only sending data pertaining to those residents who consented to participate in the network, instead of making its residents comply all at once.
