Machine-translated summary — verify against original

Between May 9 and May 12, 2023, the Chubu Transportation Bureau conducted a safety audit of Oigawa Railway Co., Ltd. (corporate number 1080001013422), headquartered in Shimada City, Shizuoka Prefecture. The audit revealed that the company had not performed scheduled inspections of the station buildings on the Oigawa Main Line and Ikawa Line, as required by Article 41 of the Civil Engineering Standards (Implementation Standards for Railway Facilities). Additionally, inspections of station building structures as per Article 6 of the Building Inspection Standards were not conducted. Furthermore, at Kado Station, the company was aware that the building clearance was obstructed as per Article 19 of the Civil Engineering Standards but had not taken necessary measures. The bureau instructed the company to promptly carry out the required inspections, revise relevant regulations to ensure regular inspections are properly implemented, and establish a system for training staff and monitoring inspection compliance. The company was also directed to take immediate action to remove obstructions at Kado Station and to ensure proper maintenance and management of railway facilities in accordance with applicable standards and laws. The company was required to report on the measures taken by August 3, 2023.
