Violation
On December 14, 2021, during a public construction project commissioned by Sankayama Village, Kumamoto Prefecture, a worker was killed when a felled tree bounced back and hit his head. The company, Iwamoto Giken Co., Ltd., did not provide workers with education on chainsaw operation and tree felling methods, nor did it conduct special safety training related to chainsaw use. As a result, the Kumamoto District Court issued a summary order imposing a fine of 200,000 yen on the company and its representative for violations of the Industrial Safety and Health Act. The penalties were finalized on January 11, 2023. Following this incident, the Kumamoto Prefectural authorities issued a formal instruction on February 9, 2023, requiring the company to take measures such as promptly informing staff of the violation details, creating and implementing training plans to ensure compliance with relevant laws, and strengthening safety management systems at the company and construction sites.
