English summary	On July 4, 2023, Kamoue Kensetsu Co., Ltd. was prosecuted for violating the Industrial Safety and Health Act and its regulations after a workplace accident during a mountain restoration project in Minakami Town, Tone District. The company's site representative, responsible for safety and construction management, allowed workers from a related contractor to enter an area with potential danger of contact with a breaker vehicle without proper guidance measures. As a result, a worker's foot was run over by the breaker crawler, leading to the amputation of the right thigh. The company was fined 200,000 yen by Numata Summary Court, and the judgment was finalized on June 29, 2024.
