This book is recommended for those in the manufacturing industry. It's a manga published at the expense of Okura Service, a subsidiary of Okura Yusoki Co., Ltd., which provides services such as emergency repairs and regular inspections. It depicts valuable accident case studies and specific accident prevention measures, and is an 84-page story connected to the four keywords that Okura Service values. I believe it's a practical, real-life bible for those working in production. Brand new, unused. A preservation edition with a white box cover. Published March 2023 Planning: Okura Service Co., Ltd. Production: Hakuhodo Inc. / Hakuhodo Products Inc. / Manga Designers Lab Co., Ltd. Will be carefully packaged and shipped anonymously.
