basic forms of Chinese learning as Buddhism, Confucianism, and Chi-

Paekche's interest in obtaining Yamato support was probably sharp-
ened by the expansionist tendencies of
Silla,
a kingdom located east of
Paekche and the third one to emerge during the fourth century. Silla
was then allying itself with Koguryd in opposing Paekche.** Refer-
ences to Silla in Japanese chronicles, particularly in sections devoted to
the Jingu campaign against Silla, claim that the Yamato kings were
disturbed by Silla advances against small kingdoms along the Tsu-
shima Straits, an area where Yamato had traditionally exercised some
control. Thus Paekche and Yamato may have been drawn together by
a common desire to check Silla aggression.
But earlier
views
regarding Yamato's influence over kingdoms on the
southern tip of Korea, even entitling Yamato to tribute, are now ques-
tioned. Little or no valid support
can be
found for
the
claim that Yamato
was then obtaining tribute from Mimana (K: Kaya). Ueda reminds us
that the Kojiki contains no references to Mimana, that the most specific
Nikon
shoki
items are for a later time in the Yamato period, and that
Korean sources include only
a
few comments about such
a
kingdom and
none at all about its being under Yamato control. As for Kaya, which
some historians assert was a Yamato colony, Ueda believes that neither
Korean historical sources nor archaeological findings support such a
claim.

Nevertheless, the Jingu tradition, the presentation of the
seven-pronged sword (made in Paekche in 369) to a Yamato ruler, and
the 414 memorial inscription mentioning a Japanese invasion of Korea
in 391 indicate that Paekche desired Yamato's support.
The conclusion that Yamato's relations with the Korean kingdoms
had become more active during the last half of the fourth century -
when burial mounds were being built in the Saki area around Nara -
has been greatly reinforced by archaeological discoveries at sites all
over Japan that reveal a continuous flow of materials, techniques,
and immigrants from the Korean peninsula into Japan during these

the Yamato period are summarized in Ueda, Okimi no seiki, pp. 156-63; Suzuki, "Ajia

vanced into central Korea from a place called Mimana. See Yamao Yukihisa, Nihon kokka no
keisei (Tokyo: Iwanami shinsho, 1977). Ki-baik Lee, in his A New History of Korea, makes no
mention of Mimana, referring always to the southern kingdom as Kaya. Here the Nihon
shoki's references to the kingdom as Mimana will be rendered as Mimana (Kaya) but else-
where as Kaya.
