those in the mountainous regions who had to purchase it could afford
to eat it only on the first three days of the New Year.

Unfortunately, nearly all scholars who touch on the subject of diet in
the Tokugawa period cite little more than these two sources, and most
are doing so in order to support the position that commoners lived
badly in premodern Japan. Other scholars, who must rely on late-
ninteenth-century figures if they are to use any data at all, probably
overestimate the amount of rice consumed. In all probability, during
the Tokugawa period the consumption of rice steadily increased, but
most of the population ate many other staple foods as well.
The argument for the widespread consumption of rice comes from
both the beginning and the end of the period.

If rice had not been the
staple by an overwhelming proportion in the early seventeenth cen-
tury, it would not have made sense to have an economy in which rice
was the basis for calculating salaries, taxes, and land
values.
More than
two and
a
half centuries later, in 1874, rice comprised
63
percent of the
value of all farm products. One of the few estimates we have on output
and food consumption for any part of the Tokugawa period is for
Choshu in western Honshu for 1840.
19
An estimate based on output
and population places the average daily consumption of
rice
in 1840 at
53 percent of the grains consumed.
It would be unusual to find any premodern society that depended on
one grain crop for its staple; not only would it make poor use of human
and natural resources, but it also would be dangerous, for a crop
failure would cause widespread starvation. The Japanese, like most
peoples, relied on a number of staple foods. The preferred grains were
rice,
barley, and wheat, but a number of others were consumed as
well. The oldest cultivated grains in Japan were two kinds of millet
(awa and kibi) and deccan grass
(hie).
By the Tokugawa period the
Japanese also ate buckwheat
(soba)
and sorghum (Indian millet, called
morokoshi).
From prehistoric times, nuts, roots, and various tubers
have been part of the Japanese diet. But rice, introduced into Japan
some two thousand years ago, is the preferred staple, and other grains
have been considered merely substitutions, supplementary foods, or
foods to be eaten in times of famine.
