Today, there are just five shops around the lake that specialise in making high-quality funazushi, as nigorobuna has become very rare and hard to obtain. Other places, including souvenir shops across the prefecture, use more common types of carp and offer a comparatively ready-made version – funazushi cured in salt for one summer and fermented in rice for a few months in autumn – for tourists seeking to try its reputedly pungent taste. Among them all, Kitashina is the one making the most authentic funazushi by using nigorobuna and applying the oldest, most traditional preparation methods.
