Violation

Iwamoto Construction Co., Ltd. submitted a false worker injury report on January 4, 2024, claiming that an employee was injured by slipping and falling while tidying up at their company garage in Kagoshima City, after an injury sustained during concrete pouring work at the Ibusuki Port coastal construction site on July 5, 2023. The employee actually fell and sustained a bruise to the left waist and back, requiring more than four days of leave. The company and its representative director were fined by the Kagoshima Summary Court for violations of the Industrial Safety and Health Act, with the sentence finalized on August 8, 2024. This constitutes a violation of Article 28, Paragraph 1, Item 3 of the Construction Business Act.
