Walk through this 3D virtual gallery of sushi in your browser, and start with the fact that the rice used to be thrown away.
The oldest form, narezushi, was a way to preserve freshwater fish. Fish was packed in salt and rice and left to ferment for months; the lacto-fermentation stopped it spoiling, and then the rice was discarded. It came from Southeast Asia, probably the Mekong basin, and a Chinese dictionary of the fourth century already describes it. Sushi means sour-tasting. Vinegar replaced the fermentation only in the Edo period.
The old sushi still exists. Near Lake Biwa in Shiga Prefecture, funazushi is made from nigorobuna, a wild goldfish endemic to the lake. The fish are scaled and gutted through the gills, the roe kept intact, packed in salt for a year, then repacked in fermented rice annually for up to four more. Eighteen generations of the Kitamura family have made it at Kitashina since 1619.
Nigirizushi was street food. Around 1824 the chef Hanaya Yohei made or perfected it at his shop in Ryōgoku: an oblong mound of rice with a slice of fish over it, eaten at once. His rice balls were about three times the size of today's, with half the vinegar and more salt. The red vinegar he used, aka-su, was fermented from sake lees.
The most familiar sushi fish is not traditional. Raw salmon can carry Anisakis nematodes, so before refrigeration Japan did not eat it raw. Salmon sushi arrived only in the late 1980s, when Norwegian fishing companies with an oversupply of farmed fish went looking for a buyer and struck a deal with the Japanese company Nichirei for 5000 tons.
