Founded in 1960, Naniwa Kombu works with kombu to offer a wide variety of products derived from this seaweed without additives, preservatives or any other chemical seasoning. Kombu is matured for more than 3 years in warehouses with carefully regulated temperatures and humidity. Faced with reduced production and soaring prices, the company seeks to generalize the cultivation of good kombu to spread a true umami taste in Japan and around the world. With this in mind, Naniwa Kombu has developed its own brand “Tsuku-shin” and directly operates two stores dedicated to the sale of its products.
