Funazushi — Shiga, Japan

Funazushi is a narezushi, the oldest form of sushi: fish salted and fermented with rice. It mainly uses nigorobuna, a carp from Lake Biwa, preferably a female with roe. The fish is salted in spring; in summer it is washed, dried and layered with cooked rice in a barrel with a lid and weight. It ferments for months, until New Year or longer.

During fermentation, lactic acid softens the bones, and the fish can be eaten whole, sliced thinly. The taste is sour and salty, and the aroma is strong. The fermentation rice, which becomes a paste, is also used.

According to Japan’s Ministry of Agriculture, narezushi was a way to preserve fish year-round. In Shiga it is made with various lake fish, and funazushi is the most representative. It is offered at shrine festivals praying for good harvests, and Shiga’s narezushi were designated an intangible cultural property of the prefecture in 1998.

Funazushi appears at festivals, New Year and gatherings. With the decline of nigorobuna in the lake, fewer families make it at home, and many buy the fish already salted and only complete the fermentation. It is served in prefectural restaurants and sold in local specialty shops.
