Nigiri sushi Period BOrigin theory CVerified

Nigiri-zushi took on its modern form in Edo—present-day Tokyo—in the first half of the nineteenth century, roughly between 1804 and 1850.

Around 1804, a cheap red vinegar known as kasu-zu, brewed from sake lees by Nakano Matazaemon in Handa near Nagoya, began reaching Edo. Vinegared rice, until then relatively costly, could now be made inexpensively, and a trade in hand-formed sushi sold in quantity from street stalls became viable. Edo Bay was already rich in fresh fish, and pressing a slice onto a small mound of seasoned rice by hand called for no special or hard-to-acquire technique. Only once vinegar arrived cheaply in Edo did this dish stand up as a product worth selling.

The setting in which it was served shaped its form as much as anything. Early-nineteenth-century Edo was a densely packed city whose streets were lined with stand-up food stalls. Formed to order and eaten on the spot, nigiri-zushi was a style honed to fit exactly that: quick, cheap food for the crowds of an overcrowded city. Where the flow of cheap vinegar into Edo met the world of the street stall, nigiri-zushi came into being.

Ask who created nigiri-zushi and one name always comes up: Hanaya Yohei, who is said to have devised the hand-formed piece in the Bunsei era (1818–1830) at his shop before the Ekoin temple in Ryogoku.

But the claim that he alone invented it finds no support in the records of his own time. That Yohei was a real man and his shop a real place is well attested. Yet the leading cookbooks and books of manners of the period do not name him as the sole inventor. If anything, Sakaiya Matsugoro of the shop "Matsu-no-sushi" is named independently as a rival candidate. That several shops surface as candidates is itself enough to unsettle any story that credits one man. The Morisada Manko, a record of manners compiled around 1853, calls Yohei's shop a famous Edo establishment but stops short of naming him the inventor.

When hand-formed sushi first appeared in Edo can be established without leaning on the Yohei legend. A senryu verse in the Haifu Yanagidaru—"a sorcerer's hand, the way he presses the sushi rice"—was composed in 1827 and printed in 1829, and it is the oldest surviving text to mention nigiri-zushi. The verse names no inventor at all. Hand-formed sushi was already on the streets of Edo before anyone's claim to have invented it.

So what spread the hand-formed piece? Once cheap kasu-zu began circulating in Edo from 1804, the style drifted, shop by shop, from the older pressed sushi toward the hand-formed one. The Morisada Manko notes that in Edo pressed sushi fell out of use until only hand-formed sushi remained, recording that replacement from the side of a contemporary source. Yohei may well have been the first great popularizer, but he was not a lone genius conjuring the form from nothing. The record we have sits closer to a slow shift driven by the arrival of cheap vinegar than to a bright moment of invention credited to one man.
