Ichiriki Marche

When Okumura Store, originally established in 1976, reopened as Ichigiri Marche, they installed Hyokan refrigerators.

We supplied them with glass door reach-in models for selling products in their storefront, as well as walk-in coolers for back of house storage. Our goal was to create a new model for supermarkets.

Walk-In Coolers

Bitchu Nouen

Bichu Nouen, a farm in Gifu Prefecture, began using Hyokan walk-in coolers in 2018. Combining Hyokan refrigeration with Aura Pack bags, they ship corn to customers that is as fresh as when it was just picked.

Their corn, called “Asanama Tomorokoshi”, can be eaten raw. It has a high sugar content of over 16 brix and a delicious crunch that will make you smile.

Kamon Group

Kamon Group is a Nagoya company that serves a selection of seasonal fish dishes. We have installed Hyokan fridges in each of their shops, as well as their central kitchen.

Using Hyokan, they can purchase large stocks of fish when prices are low, reducing costs by roughly ¥10,000 per shop per day. In addition, they can reduce the number of deliveries to individual stores from every day to only three or four times a week. This means the central factory has three days off per week.

After installing Hyokan walk-ins for the long-term storage and aging of Hida Beef, they also began using our commercial units.

In addition, they switched from dry aging to wet aging. This led to a new brand named “Bijuku” and the realization of their desire to sell their products as gifts.
