SummaryFutaba Manufacturing Co., Ltd. was involved in a tank accessory inspection equipment construction project in Oga City, Akita Prefecture, where on May 29, 2023, a generator's oil pan fell during lifting with a crane and collided with a worker inside the tank, resulting in death. The company failed to implement measures to prevent falling objects, such as setting up restricted entry zones, despite the risk of falling causing danger to workers. Although the oil pan was previously unfastened from the generator, it was not securely removed, and the company neglected its duty to prevent falling, leading to the oil pan dropping and causing the worker's death. On September 18, 2025, the Oga Summary Court sentenced the company to a fine of 300,000 yen and one employee to a fine of 500,000 yen for violations of the Industrial Safety and Health Act and for occupational negligence resulting in death. This case is recognized as applicable under Article 28, Paragraph 1, Item 3 of the Construction Business Act.
