About this page

This page announces that the Ministry of Health, Labour and Welfare inadvertently deleted approximately 11 million administrative documents before the required retention period expired. During COVID-19 quarantine measures, questionnaires, vaccination certificates, and other documents submitted by travelers were automatically deleted approximately one month after entry, though a minimum one-year retention period was mandated. The deletion was intended to protect personal information, but occurred due to insufficient recognition that the registered data constituted administrative documents. No actual harm resulted as quarantine procedures were already completed. The ministry has implemented preventive measures to ensure proper administrative document handling in future system implementations.
