■ Brief History of Maruto Fish Hooks

The founder Tomitaro DohiDohitomi & Co., Ltd is located in the small town of Tojo, Japan. Its history goes back as far as 1892, when fish hooks were made by villagers in a very primitive method, to earn extra income. Late Mr. Tomitaro Dohi, being a foresighted and ambitious man, thought of mechanizing the industry. As no electric power was available in that age, he used an old-fashioned oil engine and began manufacturing Japan’s first machine-made hooks in 1910.

In those days, fishermen in Japan were too conservative to adopt anything different from what they traditionally used. They did not show any interest in the new products at all. Thus, Mr. Dohi faced serious difficulties, and at one time, was on the verge of bankruptcy. However, his business spirit persevered and he did not give up. Instead, he extensively toured remote fishing villages from one to another and spent his time giving away fish hooks for trial. Over time commercial fishermen were convinced of the superiority of Maruto fish hooks, especially their sharpness.

However, the mechanization process was only one step of several manufacturing stages, and there remained much to improve to develop new and better machines. After World War II, with the continuation of international trade, our markets rapidly expanded. Mr. Tomitaka Dohi, the former president, developed fully automated machines along with continuous tempering plants to meet the increased demand. Now we have the ability to produce 100 million hooks monthly.

Our technical staff spare no time and effort researching for “better hooks at lower cost”. We welcome your inquires about Maruto hooks.

President's Message

The precursor of Dohitomi & Co., Ltd was founded by Tomitaro Dohi in 1892. At that time, before the advent of fish hook machine, all fish hooks were made by hand. Craftsmen painstakingly filed down and bent them by hand piece by piece. This was really a hard work that required time and efforts and daily output was understandably no more than 1,000 pieces. Having been keenly aware of the needs to modernize the process, Tomitaro studied hard and finally succeeded in production of the first machine-made fish hooks in 1907, with the help of then-craftsmen Jyutaro Fujiwara and Ryukichi Tanaka.

Tomitaro also encountered difficulties in sales and marketing. Since the machine-made fish hooks looked slightly different from the conventional hand-made ones, fishermen criticized them by saying that they looked pale and phony and didn't even give it a try. To persuade them, Tomitaro devoted himself to promoting the new fish hooks by visiting fishermen around the country and distributing the new products free of charge. It took a long time and involved considerable efforts until fishermen appreciated the value.

Thus, our founder Tomitaro, from whom I was the third president, was ahead of anyone else in the industry, paid a great sacrifice, and overcame prejudices and difficulties, thereby creating and laying the foundation here in Banshyu, Hyogo prefecture as the top producer of fish hooks in Japan. This is why we at Dohitomi are proud of ourselves as the pioneer of machine-made fish hook production in Japan. I don't think it's an exaggeration to say that he was the founder of "Banshyu Fish Hooks," which accounts for 95% of the national production and enjoys a worldwide reputation today.

In 1914, Dohi Tomitaro Trading Company started receiving orders from overseas and steadily developing markets abroad. By doing this, the company contributed to expanding export of fish hooks and achieved remarkable success in creating the domestic and foreign demand. This can be attributable, I believe, to the dramatic improvement in performance and efficiency of fish hook production, brought about by the introduction of fish hook machine.

In 1949, Tomitaka Dohi, the successor of Tomitaro Dohi, invented the first automatic fish hook machine in Japan. Since then, we have been constantly making modifications and improvements to the machine, broadening its application and making it more sophisticated one, in order to meet our customer's various needs.

We are very honored that on the Constitution Day in Japan, November 3, 1950, Tomitaro received an award from Governor of Hyogo Prefecture to praise his great contribution in promoting and developing the regional industry.

With these great achievements and efforts made by our founder in mind, we have always been committed to the improvement of fish hook machine, standardization of quality, and cost reduction.

In 1950, under the guidance of Ministry of International Trade and Industry (MITI), Japan Industrial Standard for fish hooks, JIS-S-7001, was established. Soon after that, a dozen of factories here in Banshyu gained JIS mark certificate, and industrial standardization and quality management spread rapidly.

On December 24, 1952, we acquired JIS Mark Certificate No. 5697 from MITI of Japan, which has since then become the cornerstone of our corporate philosophy of quality management. We will continue to move forward to provide customers with better and higher-quality products that are in demand at all times.

Yoshiro Dohi, Chief Executive Officer (CEO) Dohitomi & Co., Ltd

Our Mission

Dohitomi' mission is to enhance the health and happiness of people in the world by fishing.

To this end, Dohitomi takes different approaches to two major fields of our business: fish hooks for Commercial Fishing and for Sport Fishing. We believe that these two major areas have each own mission and challenges as follows:

Commercial Fishing - Fish Hook as a Daily Necessity

In the era of world population explosion, fish have a great importance as one of the major sources of protein. This is one of the reasons why nations regard oceans as a treasure of resources and divided oceans into each own territory. In view of this, our mission as a fish hook manufacturer is to provide high quality fish hooks at a reasonable cost to fishermen in the world and help them in catching fish, which in turn feed people in the world. In this respect, fish hooks are actually a daily necessity for hundreds of millions of people on the earth.

Sport Fishing - Enjoy Fishing, Enjoy Life

Fishing as a sports or a hobby is another side of fishing that has grown remarkably in these decades and is thriving today. Anglers, whether they are professionals or one-day anglers on Sundays, are always looking for dependable fish hooks that are lazar-sharp and have superb hooking ability. Without such a good fish hook, anglers never experience the joy of fishing that is shared by anglers in the world, irrespective of age and sex. We will continue to produce fish hooks that are loved by anglers who "enjoy fishing and enjoy life." That is our mission to pursue and pleasure we also enjoy.

■ Our Philosophy

To strive as much as we can to serve the best.
To maximize output by minimizing efforts.

■ Our Code of Conduct

Always to be a pioneer
Serve to enrich the world by providing fish hooks
Enrich people's lives through most productive technologies
No progress can be gained without continuous self-examination
