Shiouni was eaten by the Royal family and aristocrats.
Our company “Tentatsu” was established in 1804, the first year of Bunka, and it was an exclusive merchant of products here in Echizen, Fukui.
The 3rd generation owner of our company, Gohei Amano, obeyed an order from the feudal load of Fukui, Haruyoshi Matsudaira to produce a preserved food using sea urchins that could be carried by soldiers during the war.
Then Gohei discovered the process of preserving the sea urchins with salt using the “salted method(塩蔵法)”.
Afterward, the method was passed down through the generations and spread along the seashore in Fukui.
The general people could not taste our product Shiouni. They were used as a tribute for the House of Tokugawa, the other feudal load, and the imperial family.
Then, it spread through the feudal lands of the whole country.
The feudal load of Nagasaki, Owari and Fukui’s Karasumi, Konowata and Shiouni respectively were considered Japans 3 major delicacies because they had a special rich taste and were difficult to obtain.
