Nagoya plans to withdraw from the nationwide online residency registry network known as Juki Net [aka the Basic Resident Registers Network], Mayor Takashi Kawamura said Tuesday.
Kawamura told internal affairs minister Kazuhiro Haraguchi he will reach his decision after he discusses the issue with city residents.
He also told Haraguchi the system should be abolished.
Only 3 percent of residents nationwide have applied for a card that allows them to access the Juki Net system, due in part to privacy concerns.
The city of Kunitachi in Tokyo and the town of Yamatsuri in Fukushima Prefecture have not joined the system.
