   While setting up the list of cases in the prefecture, staff registered the wrong file. One employee both built and approved the page. [2]

   Several inquiries after 10 a.m. revealed the error, and the file was removed; it had been up for about 45 minutes. Disclosed the same day. [1] [2]

   The prefecture said it would compensate the 490 patients whose private data appeared: 40,000 yen each for 396 whose names were shown and 20,000 yen each for the other 94. [3]

For 495 cases, the list showed patients' names, the hospitals they were admitted to or moved to, admission and discharge dates, the health centers that filed the reports and cluster names, beyond the age group and gender normally published. [2]
