THE KUMASO
There has been some dispute about the appellation "Kumaso." One high authority thinks that Kuma and So were the names of two tribes inhabiting the extreme south of Japan; that is to say, the provinces now called Hyuga, Osumi, and Satsuma. Others regard the term as denoting one tribe only. The question is not very material. Among all the theories formed about the Kumaso, the most plausible is that they belonged to the Sow race of Borneo and that they found their way to Japan on the breast of the "Black Tide." Many similarities of custom have been traced between the two peoples. Both resorted freely to ornamental tattooing; both used shields decorated with hair; both were skilled in making articles of bamboo, especially hats; both were fond of dancing with accompaniment of singing and hand-clapping; and both dressed their hair alike. Japanese annals use the word "Kumaso" for the first time in connexion with the annexation of Tsukushi (Kyushu) by the Izanagi expedition, when one of the four faces of the island is called the "land of Kumaso." Plainly if this nomenclature may be taken as evidence, the Kumaso must have arrived in Japan at a date prior to the advent of the immigrants represented by Izanagi and Izanami; and it would further follow that they did not penetrate far into the interior, but remained in the vicinity of the place of landing, which may be supposed to have been some point on the southern coast of Kyushu. Nor does there appear to have been any collision between the two tides of immigrants, for the first appearance of the Kumaso in a truculent role was in A.D. 81 when they are said to have rebelled.
The incident, though remote from the capital, was sufficiently formidable to induce the Emperor Keiko to lead a force against them in person from Yamato. En route he had to deal with "brigands" infesting Suwo and Buzen, provinces separated by the Inland Sea and situated respectively on the south of the main island and the north of Kyushu. These provinces were ruled by chieftainesses, who declared themselves loyal to the Imperial cause, and gave information about the haunts and habits of the "brigands," who in Suwo had no special appellation but in Buzen were known as Tsuchi-gumo, a name to be spoken of presently. They were disposed of partly by stratagem and partly by open warfare. But when the Yamato troops arrived in Hyuga within striking distance of the Kumaso, the Emperor hesitated. He deemed it wise not to touch the spear-points of these puissant foes. Ultimately he overcame them by enticing the two daughters of the principal leaders and making a show of affection for one of them. She conducted Japanese soldiers to her father's residence, and having plied him with strong drink, cut his bow-string while he slept so that the soldiers could kill him with impunity. It is recorded that Keiko put the girl to death for her unfilial conduct, but the assassination of her father helped the Japanese materially in their campaign against the Kumaso, whom they succeeded in subduing and in whose land the Emperor remained six years.
The Kumaso were not quelled, however. Scarcely eight years had elapsed from the time of Keiko's return to Yamato when they rebelled again, "making ceaseless raids upon the frontier districts;" and he sent against them his son, Yamato-dake; with a band of skilled archers. This youth, one of the most heroic figures in ancient Japanese history, was only sixteen. He disguised himself as a girl and thus gained access to a banquet given by the principal Kumaso leader to celebrate the opening of a new residence. Attracted by the beauty of the supposed girl, the Kumaso chieftain placed her beside him, and when he had drunk heavily, Yamato-dake stabbed him to the heart,* subsequently serving all his band in the same way. After this, the Kumaso remained quiet for nearly a century, but in the year 193,** during the reign of the Emperor Chuai, they once more rebelled, and the Emperor organized an expedition against them. He failed in the struggle and was killed by the Kumaso's arrows. Thenceforth history is silent about them.
*The Chronicles relate that when the Kumaso was struck down he asked for a moment's respite to learn the name of his slayer, whose prowess astounded him. On receiving an answer he sought the prince's permission to give him a title, and declared that instead of being called Yamato Oguna, the name hitherto borne by him, he should be termed Yamato-dake (Champion of Japan) because he had conquered the hitherto unconquerable. The prince accepted the name, and then gave the Kumaso his coup de grace.
**It should be understood that these dates, being prehistoric, are not wholly reliable.
Who, then, were they? It is related in the Chronicles that, after breaking the power of the Kumaso, the Emperor Keiko made a tour of inspection in Tsukushi (Kyushu), and arriving at the district of Kuma, summoned two brothers, princes of Kuma, to pay homage. One obeyed, but the other refused, and soldiers were therefore sent to put him to death. Now Kuma was the name of the three kingdoms into which the Korean peninsula was divided in ancient times, and it has been suggested [Aston] that the land of Kuma in Korea was the parent country of Kuma in Japan, Kom in the Korean language having the same meaning (bear) as Kuma in the Japanese. This, of course, involves the conclusion that the Kumaso were originally Korean emigrants; a theory somewhat difficult to reconcile with their location in the extreme south of Kyushu.
The apparent silence of the annals about the subsequent career of the tribe is accounted for by supposing that the Kumaso were identical with the Hayato (falcon men), who make their first appearance upon the scene in prehistoric days as followers of Hosuseri in his contest with his younger brother, Hohodemi, the hero of the legend about the palace of the sea god. Hohodemi according to the rationalized version of the legend having obtained assistance in the shape of ships and mariners from an oversea monarch (supposed to have reigned in Korea), returned to Tsukushi to fight his brother, and being victorious, spared Hosuseri's life on condition that the descendants of the vanquished through eighty generations should serve the victor's descendants as mimes.
"On that account," says the Chronicles, "the various Hayato, descended from Hosuseri to the present time, do not leave the vicinity of the Imperial palace enclosure and render service instead of watch-dogs." The first mention of the name Hayato after the prehistoric battle in Kyushu, occurs in the year 399, when Sashihire, one of the tribe, was induced to assassinate his master, an Imperial prince. This incident goes to show that individual members of the tribe were then employed at Court; an inference confirmed fifty-one years later, when, on the death of Emperor Yuryaku, "the Hayato lamented night and day beside the misasagi (tomb) and refused the food offered to them, until at the end of seven days they died."
It can scarcely be doubted that we have here a reversion to the old custom which compelled slaves to follow their lords to the grave. The Hayato serving in the Court at that epoch held the status generally assigned in ancient days to vanquished people, the status of serfs or slaves. Six times during the next 214 years we find the Hayato repairing to the Court to pay homage, in the performance of which function they are usually bracketted with the Yemishi. Once (682) a wrestling match took place in the Imperial presence between the Hayato of Osumi and those of Satsuma, and once (694) the viceroy of Tsukushi (Kyushu) presented 174 Hayato to the Court.
