Machine-translated summary — verify against original

Between November 25 and 26, 2025, Yamaman Co., Ltd. underwent a safety audit which revealed areas needing improvement. Specifically, during the inspection of vehicle equipment standards under Article 27, Paragraph 3, of the Railway Equipment Standards, some measurement values related to brake system tests exceeded internal limits but were recorded without verification. The company is instructed to ensure proper verification and management of inspection data to maintain appropriate vehicle maintenance. Additionally, regarding physical fitness tests for personnel directly involved in train operation, it was confirmed that: 1. Vision tests for train operators were not properly conducted according to the standards set by the Ministerial Ordinance on Driver's Licenses and internal regulations, and operators were engaged in driving without necessary re-tests. 2. The criteria and procedures for physical function tests, including vision, hearing, and health conditions, are not appropriately established in relation to the Ordinance. The company is required to establish and properly implement standards for physical function tests, including vision, hearing, and health, and to manage test results appropriately. The guidance is issued by the Kanto Transport Bureau, with a reporting deadline of April 27, 2026.
