About us

Company history

The history of Akasaka Diesels goes back to 1910 with the repair of boat engines in the fishing village of Yaizu. Since then, we have developed and manufactured numerous fishing boat engines, expanding our business along with the development of the fishing industry. The Akasaka Diesel brand name has grown to be known not only in Japan, but also around the world. With superior quality and technology, we have been one of the driving forces behind making Japan one of the world's few large seafood industries. At the same time, we have actively advanced in the field of commercial cargo and oil transportation shipping. We have confronted the tasks of making engines smaller and more powerful to develop new products to meet the needs of the age. In recent years, we have also applied our technological capabilities and expertise gained from manufacturing engines to other fields. And our business areas are expanding.
