History of Ohguchi Suisan

About Tomoyuki Arai (founder) and the history of the company

Tomoyuki Arai, the founder of Ohguchi Suisan Co., Ltd. was born in November 1908 in a farmhouse in Yuyagahara-machi, Kanazawa City (then Yuyagahara, Asakawa Village, Kawakita County) at the foot of Iouzen.
The second son of five siblings, he went to work for a fishmonger in Kanazawa at the age of 14. After training in Osaka, he set up his own store in 1940, renting a corner of a salt and dried fish wholesaler in the "Ohmicho-ichiba".

At the time, the economy was heavily regulated due to the war, and the distribution channels for fresh fish were divided into those for the general public, those for business use, and those for large orders.
He became the managing director of Kanazawa Fisheries Products Ohguchi Distribution Co. This company is the root of today's Ohguchi Suisan.

About Tomoyuki Arai (founder) and the history of the company.

Betting on reconstruction from the end of the war

After the war, the price of goods skyrocketed due to a shortage of supplies. Against this backdrop, the founder, Arai, began selling "dish plates" with regular coupons. This was a business method that was based on the customer's point of view, rather than the seller's price.

Instead of focusing on high-end fish, he stocked up on popular fish such as mackerel, sardines, squid, and flounder, and then reduced the price to a level that customers could afford. He continued to provide fish at low prices to the public by making no profit.

"Business is built on the blessings of nature, logistics, employees, customers, and all of the above. That is the starting point of business."
We will continue to move forward with the philosophy of Arai, a man of business spirit.

Evolving with the times

After 1955, with the change to a car-oriented society, the construction of a parking lot became an urgent necessity for the entire "Ohmicho-ichiba", and Arai worked hard to construct a parking lot in Ohmicho.
Also, the evolution of commercial appliances was remarkable, and large refrigerators were introduced, making it possible to serve fresh fish in the freshest condition.

Around the time of the establishment of the central wholesale market in 1966, the creation of a new structure as a company also began. In 1983, the Central Collection and Delivery Center was established outside the central market. With this center as a base, we began to develop customers in Kanazawa and its suburbs, as well as outside the prefecture, by making full use of a computerized ordering system and a rational transportation system.

Evolving with the times.

With "Sho-kon ( Ohguchi Suisan's business spirit ) " in mind,
We will continue to be a company that is needed by our customers

With the passage of time in the Heisei and 2022 eras, the technology of the world has greatly evolved. Delivery routes have become more efficient, cooling methods have become more sophisticated, and it is now possible to transport fresh fish throughout Japan and overseas.
In addition, the development of information transmission technology has made it possible to exchange information quickly, enabling us to purchase large quantities of delicious fish at low prices and provide them to our customers.

It is important to change things as times change and technology evolves. Even under such circumstances, the spirit of Ohguchi Suisan's business spirit of "putting the customer first and providing large quantities of delicious fresh fish at low prices" remains unchanged.

We will continue to strive to be a company that is familiar to and needed by our customers.

He was instrumental in the construction of the arcade at "Ohmicho-ichiba".

Around this time, there was talk of building an arcade in "Ohmicho-ichiba" to provide shade from the sun and to protect against snow. Although permission to install an arcade was not readily granted, Tomoyuki Arai, together with the Arcade Reinforcement Construction Committee, worked hard for the installation of an arcade. As a result, the arcade street, which is now the symbol of Ohmicho, was gradually constructed.
