In February 2011, the Japan Pension Service (JPS) launched "Nenkin Net", an internet service for its customers to use personal computers to access their pension information at any time 24 hours a day.

The Nenkin Net started as a service for customers to refer to their coverage history, number of covered months, their base income for benefits calculation purposes, contribution amount, and contribution payments records. Subsequently reflecting customers' needs, the service has been gradually improved with new functions; customers can now have their future benefits estimated, view various types of letters and notices which are mailed by post to customers, receive support when preparing reports to be submitted to the JPS. The service is also available on a smartphone.

The JPS's exclusive call centre supports customers to use the Nenkin Net. Customers without computers may receive the service at selected municipal offices, where their pension records and benefits estimate information can be printed.
