Violation

On March 11, 2022, Kyo-shin Construction Co., Ltd. conducted a renovation of a mixed-use residential and commercial building in Inage-ku, Chiba City. During this project, the company allowed subcontractor workers to use a scaffolding walkway without the legal exemption, despite the risk of falls and without implementing necessary safety measures to prevent worker accidents. Based on this fact, the Chiba Summary Court issued a summary order (Case No. 30898 of 2022) for violations of the Industrial Safety and Health Act, imposing a fine of 200,000 yen. This is recognized as a violation under Article 28, Paragraph 1, Item 3 of the Building Business Act. The authorities instructed the company to take measures to prevent recurrence, including promptly informing staff about the violation and ensuring compliance with relevant laws, and to report the measures taken within 30 days.
