Message from the president

Based on our Management Philosophy of "bringing happiness and smiles to every person involved with Isoya" we have concentrated ever since our founding on creating the highest quality Japanese nori.
As the third president, I myself have traveled to every production area in Japan to collect nori that I have personally surveyed for integrated production at our own factory.
Japanese nori is thicker than that from China or Korea.
It is crispy and has a melt-in-the-mouth flavor, with a distinct sweetness that spreads in your mouth.
Nowadays in every part of the world we can find Japanese food being enjoyed.
We are a nori concierge that can respond to our customers' requests for more delicious nori.
We can suggest to you the best nori for different dishes and usages.

Koichi Gomi, the third president
