What is it?
Funazushi is Shiga's fermented nare-zushi: salt-cured crucian carp is layered with cooked rice and lactic-fermented. Unlike modern vinegared-rice sushi, its pronounced acidity, dairy-like aroma, concentrated fish, and softened bones come from fermentation.
Lake Biwa's endemic nigorobuna is the prized fish, especially roe-filled females. Other fish are also made into nare-zushi, so funazushi should not be used as a name for every fermented fish preparation.
History and local context
Spring-caught fish are salted, washed around midsummer, packed with rice, and fermented for months; some specialists age theirs through two winters. Shiga notes that by New Year the acidity rises and the bones soften.
Nigorobuna stocks fell under pressures including habitat loss and introduced fish. Shiga and fishers continue release and resource-management programs, making fish species, origin, sex, aging period, and refrigeration useful buying checks.
How to enjoy it
Let a 2–3 mm slice warm slightly, taste it plain, then try it with fermented rice, sake, tea over rice, or in clear soup. Keep commercial funazushi refrigerated as labeled; first-time home fermentation should follow Shiga's manual or a fishery workshop rather than an improvised raw-fish method.
Availability varies by maker, season, and destination.
