History and origin
It is thought to have been eaten from the mid-Edo period onward. It is presumed that on the islands, where annual taxes were paid in salt and salt was precious, the brine used for drying fish was reused rather than discarded, and the liquid that fermented over time was passed down. Before the Meiji period it was called "shochiruboshi," and there is reportedly a record in Niijima Village of it being offered as tribute in the Edo period.
When it is eaten
It is eaten as a side dish with rice and as a snack with shochu or sake.
How it is eaten
