THE YAYOI PERIOD IOI
Chinese language despite centuries of Chinese rule. Divergences be-
tween Korean and Japanese must
have
been very great
by the
time of the
fourth-century ruler Yuryaku. Indeed, interpreters were needed by
Korean heads of be (saddlers, weavers, potters, and painters) when
communicating with their craftsmen.
Evidence for the physical characteristics of the Yayoi people comes
from about a thousand skeletons found in southwest Japan, mostly
belonging to Early and Middle Yayoi periods when the jar-burial sys-
tem (which provided the best conditions for preservation) was popu-
lar. No evidence of population displacement has been found in the
physical remains of north Kyushu. Early Yayoi people in north and
west Kyushu were taller by an average of two centimeters, but they
were otherwise little different from their Jomon predecessors. It is
now known that the Early-to-Middle Yayoi people of northwest and
south Kyushu were rather similar to the Tsugumo people of the Late
Jomon.59 Not until the end of
Yayoi
was the impact of better nutrition
and new genetic types felt. By that time, differences between Yayoi
and Jomon people had become clear. Their faces were then markedly
flatter, beginning a slow trend toward mongoloid features that contin-
ued until the sixteenth century. The stature for males had increased to
about 162 centimeters in the Early Yayoi but declined noticeably dur-
ing the Middle Yayoi. Longevity, it is estimated, was by then one year
longer. Like the Jomon people, the Yayoi people were not homoge-
neous,
but they were looking more alike by the end of the Yayoi
period. On the whole, the weapons-burying people of the southwest
tended to have long skulls, and those of the bell-burying people of the
east were rounder.

Some nine thousand footprints of feet 23 to 25
centimeters long were found 3.5 meters below the surface of the Mid-
dle Yayoi Uryudo site in Higashi Osaka City. The feet were 25 to 27
centimeters long at Itazuke, Even today the Kawachi people of central
Japan are regarded as smaller than those of Kyushu. Nutrition had a
greater effect on physical change than did new racial strains, although
the latter must have been quite important. Indeed, the dramatic
change in the size and height of the younger generation in Japan after
World War II is likewise attributed to the availability of larger
