Endo Construction Co., Ltd. is engaged in construction work and was responsible for construction and safety management at the site of the 2024 prefectural road bridge maintenance (disaster-related) work commissioned by the Omachi Construction Office, Nagano Prefecture. Employee A, who is a site manager, was responsible for safety management at the site. On May 27, 2025, at the construction site within the general prefectural road Uruga-Ikeda Line, Worker B was instructed to perform shoulder repair work using a drag shovel. The site was a shoulder where guardrails had been removed for construction, and there was a risk of the shovel overturning or falling, which could endanger the worker. A guide was supposed to be positioned to direct the shovel to prevent accidents, but during the incident, no guiding was provided, and necessary measures to prevent danger from machinery were not taken. As a result, Endo Construction Co., Ltd. and A received summary orders imposing a fine of 200,000 yen each for violations of the Industrial Safety and Health Act, and their penalties were finalized. This constitutes a violation of Article 28, Paragraph 1, Item 3 of the Construction Business Act.
