The word "AMITA" is derived from the combination of two Chinese characters

pronounced "ami" and "ta" respectively. The combination of these two words means "Strong Net"

Today AMITA machines are trusted the world over by net makers in more than 50 countries on five continents. This success is built upon over half a century of dedication to the continual improvement of fishing net machines through research and experimentation. AMITA's commitment to excellence dates back to 1817, when Tajibei Yamamoto, great-great grandfather of the current owner (Yoshiji Yamamoto), began hand-making and selling hemp fishing nets.

More recently 1951, marks the year that our company entered the international market-place with the sale of fish making machines to six countries including Finland and Brazil. Over the ensuing years, AMITA developed a reputation as the world's leading manufacturer of fishing net machines and related machinery.

The machines built in our factory couple the workmanship and durability that AMITA is famous for with new materials, technology, engineering, and customer insights. Machines that are increasingly user-friendly, efficient, and productive are the result of this unique combination.

Since its beginning, AMITA has stayed on the forefront of net-making technology. Today, Computer Aided Design (CAD) and proprietary software allow us to design machines that meet the specifications of individual customers. Additionally, in-depth know-how in the areas of electronics and mechanical engineering (as they relate to the net-making process) allow for flexible approaches with regard to innovative new designs.

We are not merely a net machine manufacturer, however. As a company with a tradition that reaches back over 200 years, AMITA possesses the knowledge and experience to design and operate plants adapted to local conditions...anywhere. To enable customers to get maximum performance from their AMITA net machines various technical and management consulting services are offered. Obviously maintenance of the installed machines is a part of this commitment, but follow-up services at other levels, to ensure full customer satisfaction, are also conducted.

Our company is organized to follow-up developments and customer requirements in a wide range of areas...beyond merely technical matters. Of course, parts for previous models, as well as, all current models are always available. Additionally AMITA sends training staff to locations all over the world, and accepts trainees at its headquarters to enable customers to operate and maintain their machines properly. We believe that it has the responsibility to establish and maintain a system for following-up every aspect of its business: from manufacturing machines and designing entire plants to maintenance and training.

To ensure that AMITA maintains its leadership in the fish netting industry it continues to strengthen the training structure of its employees. While specialization is promoted, it is balanced against a desire to build character within the work-force. For example, employees are encouraged to enhance their English skills, develop their knowledge of computers, and improve their overall understanding of the world throughout the course of the day. This InterNet site is one such result of our particular business approach, as well as its long history of embracing new technology to better communicate with customers around the world.

As a result of all these endeavors, AMITA's has become a responsible world citizen, whose network is as vast as the seven seas.
