Confirmed entity match

On November 24, 2023, Kikuno Sekigyo Co., Ltd. submitted a false worker injury report to the Ube Labor Standards Inspection Office, claiming a worker's injury would result in six months of leave, which was not true. On February 28, 2024, during an inspection, the company made false statements to conceal the incident. On December 9, 2025, the Ube Summary Court sentenced the company and its former CEO to a fine of 200,000 yen each for violations of the Industrial Safety and Health Act, specifically Articles 100, Paragraph 1, and 91, Paragraph 1, of the same law. The court's decision was finalized on December 25, 2025. These actions are deemed to violate Article 28, Paragraph 1, Item 3 of the Construction Business Act.
