Invaded simultaneously by the forces of China and Shiragi, it was also torn by internal dissensions, and could not coöperate in any effective manner with the Japanese navy, which consequently withdrew, leaving Kudara to its inevitable fate. The final fall of Kudara occurred in 670, and a few years later the third Korean district of Koma was also defeated by China. Shiragi subsequently sent occasional tribute to Japan, but was never afterward included in the Japanese dominions. The Emperor Tenchi, reviewing the history of his country's relations with Korea, seems to have arrived at the definite conclusion that the wisest policy was on the side of abandoning all idea of recovering Kudara, and devoting Japan's energies solely to organizing measures of defense against foreign attack. He accordingly adopted every possible means of promoting military efficiency. It should be remembered that Japan had not only lavished money and blood for Korea, but also had outlived the days when the civilizing influence of the continent had to come by way of the peninsula and had already been in communication with the source of enlightenment, China. It was during the reign of the same Emperor Tenchi that China sent an envoy to the court of Japan, and the latter country dispatched an embassy in return, so that the two empires were brought into more friendly relations than before. [Illustration: THE WORSHIP OF THE BEAR AMONG THE AUTOCHTHONS (AINOS) OF EZO] The curious "Hairy Ainos" of northern Japan hold the bear in extreme sanctity. They catch the bear when young and bring him up on human milk, a nurse being deputed to him. Then he is transferred to a cage and, when he is old enough to be slain, on the day of sacrifice the whole village turns out armed with bows and arrows, the cage is opened and each one strives to send home the fatal shaft. The chief prays the bear to pardon the violence done him, requests benefits from the now deified carcass, and presents offerings. They then behead and skin the bear, and begin an orgie which lasts several days.
