Japanese Prime Minister Fumio Kishida pledged Wednesday to dispel public anxiety following revelations of errors related to the "My Number" national identification card system.

At a news conference held after the ordinary Diet session ended, Kishida said he has instructed relevant ministers to thoroughly review the My Number system and take measures to prevent further trouble by fall this year.

Earlier in the day, the government set up a headquarters to deal with a spate of registration errors and other problems linked to the system.
