Our Role

Based in the wholesale markets of Osaka, Kyoto, and Kobe, we contribute to the stable supply of marine products through a network connecting domestic production areas and the world.

With offices in major wholesale markets in Osaka, Kyoto, and Kobe, we play an important role in delivering marine products that arrive not only in Japan but also overseas to consumers throughout the Kansai region. The wholesale system that connects the major cities of Keihanshin is an unprecedented strength of our company.

In addition, the catch of fresh seafood may fluctuate greatly depending on natural conditions such as the weather, but we have achieved a stable supply through a network with producers nationwide.

Strengths of us / Our features

  1. 60,000 items handled by more than 4,000 suppliers

    We purchase and sell over 60,000 items such as fresh fish, frozen fish, salted dried fish, and processed products from more than 4,000 suppliers to meet the wide range of customer needs.

  2. We provide a wide range of consulting.

    By acting as a bridge between shippers and consumers, we feedback various information to the product development department of processed product manufacturers, and conversely make sales proposals to retailers. Our strength is that we can provide a wide range of consulting from producers to retailers and restaurants, not just product distribution.

  3. We have business connections with many producers, suppliers, and customers in Japan and overseas.

    We collect a variety of information through these producers, suppliers, and customers. Useful information is organized and analyzed by our own system, which we utilize in our sales activity giving us a strong competitive advantage.
