Quality

The blessings of the Ariake Sea of Japan

We purchase high-quality nori from producers with whom
we maintain good relations.

The Ariake Sea of Japan is a well-known production area for nori. Isoya has bidding rights from the Nori Fishing Cooperative Association. At local bidding sessions our staff personally place offers for the best dried nori as raw material, to purchase a year's worth.

Isoya's nori is produced from start to finish entirely at our own factory.

Nori purchased from local producers is taken to our factory to create products through integrated management of every process.

As a manufacturer, we handle every aspect of production out of our great responsibility to our clients, from (1) the roasting process, (2) cutting, (3) canning, and then (4) bagging on automated lines, followed by (5) passing strict inspections, (6) packaging, and finally (7) shipping preparations.

We won the Monde Selection Gold Award for three consecutive years.

The Monde Selection assesses food and other consumer products to certify the highest quality items as an international review organization. The selection is impartially made by a group of independent expert judges, just like the Michelin Guide. Headquartered in Belgium, the selection focuses on aspects like taste, raw materials, hygiene, packaging, and aptness of the labeling.
Nanko Apricot Seaweed (from the Ariake Sea), which won the gold award for three consecutive years, is elegantly seasoned nori from the Ariake Sea that has the rich aroma of the seashore and a wonderful crispness, flavored with a sauce using Nanko plums. This is a superb product with a crisp texture and a lingering aroma of plum.

Hygiene management based on FSSC 22000

Our unwavering commitment to food safety and quality is demonstrated by our achievement of FSSC 22000 certification, an internationally recognized food safety management system. FSSC 22000 is based on ISO 22000 (Food Safety Management Systems) and ISO/TS 22003 (Food Safety Management Systems - Requirements for Prerequisite Programs) and employs Hazard Analysis and Critical Control Points (HACCP), a scientific and systematic approach to identify and manage food safety risks.
This certification requires the establishment of a food safety management system throughout the entire supply chain, from raw material procurement to manufacturing, distribution, and sales. We comply with food safety laws and regulations, and through continuous improvement activities, we strengthen our food safety management system.
The achievement of FSSC 22000 certification has enabled us to enhance food safety and quality through the clarification of hazard analysis and critical control points and the establishment of a management system to control them, thereby increasing customer confidence.
Going forward, we aim to contribute to society by strengthening our global market competitiveness through meeting international standards and providing safe and high-quality food to our customers.
