Throughout Japan, there are a few communities that have refused to join Juki Net. In Tokyo-to, I believe two such examples are Suginami-ku and Kunitachi-shi. There are others elsewhere. Why did these communities refuse Juki Net? I'm not sure, but I suspect they have a reasonable number of wealthy and influential people who value keeping as much privacy as possible. Considering all the blunders of government (especially) data mismanagement, including losing the national pension records of thousands of citizens, keeping as much personal data as possible out of any government's hands is the best policy.
