Violation

Yugen Kaisha Hosoya Kenzai received an administrative instruction from Ibaraki Prefecture on January 20, 2023, under the Construction Business Act, Article 28, Paragraph 1, Item 3. This was in response to violations of the Labor Safety and Health Act (Law No. 57 of 1972), specifically Article 21, Paragraph 2, which resulted in a summary fine of 300,000 yen imposed by the Mito Summary Court on September 8, 2022, and confirmed on September 29, 2022. The violations involved failure to adhere to safety regulations during work activities, and the company's employee was also convicted of criminal negligence resulting in death under the Penal Code (Law No. 45 of 1907), Article 211, due to neglect of duty and failure to ensure safety, leading to the death of a worker. These facts constitute grounds for action under the Construction Business Act, Article 28, Paragraph 1, Item 3. The instruction mandates the company to take measures such as promptly informing staff of the violations and penalties, creating and implementing training plans to ensure compliance with laws and regulations, and conducting ongoing training. The company must report in writing once these measures are taken, including any other measures implemented.
