Things remained thus for nine years. Tribute-bearing envoys arrived at intervals from Koma, but with Shiragi there was no communication. At last, in 571, an official was sent to demand from Shiragi an explanation of the reasons for the destruction of Mimana. The intention may have been to follow up this formality with the despatch of an effective force, but within a month the Emperor Kimmei died. On his death-bed he is said to have taken the Prince Imperial--Bidatsu--by the hand and said: "That which comes after devolves on thee. Thou must make war on Shiragi and establish Mimana as a feudal dependency, renewing a relationship like that of husband and wife, just as it was in former days. If this be done, in my grave I shall rest content." Twelve years passed before Bidatsu took any step to comply with this dying injunction. During that long interval there were repeated envoys from Koma, now a comparatively feeble principality, and Shiragi made three unsuccessful overtures to renew amicable relations. At length, in 583, the Emperor announced his intention of carrying out the last testament of his predecessor. To that end his Majesty desired to consult with a Japanese, Nichira, who had served for many years at the Kudara Court and was thoroughly familiar with the conditions existing in Korea. Nichira came to Japan, but the annals indicate that his counsels were directed wholly against Kudara, which was ostensibly on the friendliest terms with Japan, and not at all against Shiragi, whose punishment was alone in question. Besides, instead of advising an appeal to arms, he urged the necessity of developing Japan's material resources, so that her neighbours might learn to count her formidable and her people might acquire ardour in her cause. Whether the wisdom of this advice appealed to Bidatsu, or whether the disputes consequent upon the introduction of Buddhism paralyzed his capacity for oversea enterprise, he made no further attempt to resolve the Korean problem.
