On February 20, 2026, a safety audit was conducted on Kabushiki Kaisha Gatsusan Asahi Shinko Kosha. The audit revealed non-compliance with Article 4 of the 'Single-line Fixed Circular Special Ropeway Maintenance Rules' (hereafter 'Maintenance Rules'), which stipulates that inspections should be conducted every month based on the cumulative usage period. It was confirmed that inspections had not been performed monthly, as the company had altered procedures outside the Maintenance Rules, indicating insufficient understanding of regulations and inadequate involvement of management in safety oversight. The company was instructed to carry out inspections and maintenance in accordance with the Maintenance Rules, verify that procedures align with the rules, and implement improvements if discrepancies are found. Additionally, the company must provide necessary education and training to prevent similar incidents and establish a robust safety management system. The report was issued by the Tohoku Transport Bureau.
