How the Error Occurred and Was Discovered

A 50-year-old first sergeant at the Nagasaki Regional Cooperation Headquarters made the data entry mistake in October 2025 while inputting exam results. The two failed candidates from Nagasaki Prefecture were incorrectly marked as passing. The error remained undetected for five months until March 2026, when staff reviewing related documents identified the problem.

Disciplinary Actions Against Five Officers

The 50-year-old first sergeant who made the entry error received a one-month salary reduction of 1/15. A 40-year-old major who failed to verify the data received a one-month reduction of 1/10. A 50-year-old major overseeing both received a formal reprimand. The Western Army Regional Command in Kumamoto also disciplined two officers for insufficient data verification, each receiving one-month reductions of 1/30.

Official Response and Commitment to Prevention

Lieutenant General Seiji Toriumi, commander of the Western Army Regional Command, issued an apology for the inconvenience caused to those affected. The Self-Defense Force stated it would strengthen verification procedures to prevent similar errors. Officials emphasized that the two candidates who received false notices ultimately did not join the force.
