The Basic Resident Registers Network (住民基本台帳ネットワーク Jūmin kihon daichō nettowāku?) or Juki Net (住基ネット Jūki netto?) is a national registry of Japanese citizens. It was ruled constitutional by the Supreme Court of Japan on March 6, 2008[1] amidst strong opposition.

Registry content[edit]

The registry contains the following information for each citizen:[2]

  • Name,
  • Address,
  • Date of birth,
  • Gender,
  • An 11-digit individual number,
  • Any modification of the previous fields over time.[3]


The initial phase of the network started on August 5, 2002, which implemented, literally, Three statutes for online government and local government executive procedure on June 7, 2003, and full operation on August 25, 2003.[4] The network is run by the Local Authorities Systems Development Center, a government-backed IT provider in Tokyo.[3]

Among more than 1,700 local governments in Japan, only two (Kunitachi, Tokyo and Yamatsuri, Fukushima) have refused to join the network as of May 2009.


Some fear misuse of the data[3] or data spill. Some consider it a violation of their privacy.[3] Many suits have been filed by cities or citizens who would not want to be registered, some were successful and some were not.[3]

The registry is opposed by the Democratic Party of Japan, the Liberal Party, the Japanese Communist Party and the Social Democratic Party.[2]
