In the lead up to the turn of the millennium, few computers were able to properly represent the year 2000, leaving people worried about what would happen when midnight on New Year's eve struck. Now the same issues could arise in Japan when the current emperor steps down in April next year. The Japanese calendar is based on era names that coincide with the rule of its emperors.
