Abstract
For the introduction of the My Number system, information system development with the national government has been advanced. Among others, budgetary allowances have been made for the maintenance in local governments by the government granting maintenance cost subsidies. While the budget amount of measures related to information and communication technology in the Japanese government is on a downward trend, a reasonable amount has been invested in order to introduce My Number system. In January 2017, concerning the maintenance cost subsidies related to the introduction of the My Number system, the Audit and Inspection Bureau reports temporary reports to the Diet and the Cabinet. In this research, by referring to the occasional report, we clarify challenges on procurement mainly concerning information system development in public institutions.
