English summary	Between October 17 and 19, 2022, the Hokkaido Transport Bureau carried out a safety audit of Hakodate City. The audit revealed deficiencies in safety management and inspection practices. As a result, the bureau issued administrative guidance to Hakodate City, requiring the implementation of corrective measures. The guidance specifies that Hakodate City must establish a system to accurately grasp on-site conditions, regularly verify operational status, organize issues, and strengthen safety management to ensure the feasibility of improvements. Specific issues include: 1) Management of track wear measurement, which exceeded the scheduled period in fiscal year 2021; 2) Inspection procedures for substation equipment, particularly insulation resistance tests at Komaba-cho Substation, which were conducted improperly and did not meet standards; 3) Proper recording and storage of monthly VVVF inverter inspections for train models 2000, 3000, and 9600. Hakodate City is required to review inspection methods, ensure proper execution and judgment based on standards, and maintain accurate records. The bureau requested that Hakodate City report on the corrective actions taken by December 8, 2022.
