Nuchima-su makes sea salt from Pacific seawater drawn at Miyagi Island in Okinawa. Its proprietary spray process turns seawater into a warm mist and crystallizes the salt without conventional pan boiling; the producer sells the finished salt through its official shop.
The producer traces Nuchima-su to an idea developed by founder Masakatsu Takayasu after Japan’s salt market was liberalized in the late 1990s. He adapted fine-spray equipment originally associated with orchid cultivation into a salt-making process.
The raw material is seawater taken from the Pacific side of Miyagi Island. Production takes place at the company’s island factory, while the official shop identifies the same company as legal seller and order operator.
Miyagi Island seawater is sprayed as a fine warm mist so that water evaporates and the remaining marine components crystallize as salt, rather than being concentrated in a conventional boiling pan.
