All these were groups organised on the basis of the special professions pursued by the members of each respective group, although many of the groups might consist eventually of persons of homogeneous blood. Besides these groups there was another kind based solely on identity of blood, that is to say, on the principle of racial affinity. When we examine the circumstances of the formation of such groups, we generally find that a body of immigrants at a certain period was constituted as a group by itself by way of facilitating the administration. Sometimes several bodies of immigrants, differing as to the period of immigration, were formed into one large corps. In the corps thus formed, there would have naturally been people of various occupations, connected only by blood relationship.
The third kind of group was quite unique in the motive of its formation. It was customary in ancient times in Japan to organise a special group of people in memory of a certain emperor or of some noted member of the imperial family. This happened generally in the case of those personages who died early and were much lamented by their nearest relations. Sometimes, however, a similar group was formed in honour of a living emperor. As it was natural that groups thus formed paid little attention to the consanguinity of their members, it is presumable that they might have consisted of persons of promiscuous racial origin. On the other hand, it is also clear that there could be no necessity for conglomerating intentionally men of heterogeneous racial origin in order to effect a mixture of blood between them. Such a motive is hardly to be considered as compatible with the spirit of the age in which the scrutinising of genealogies was an important business. Added to this, the organisation of a group out of people of different stocks would have incurred the danger of making its administration exceedingly difficult. As to the profession pursued by persons belonging to such a group, any generalisation is difficult. Some groups might have been organised mainly from the need of creating efficient agricultural labour, in order to provide for the increasing necessity of food stuffs; in other words, from the need for the exploration of new lands. Other memorial groups might have been formed for the sake of providing for the need of various kinds of manual labour, and must have contained men of divers handicrafts and professions, so as to be able to provide for all the daily necessities of some illustrious personage, to whom the group was subject. When men of promiscuous professions formed a group and produced sundry kinds of commodities, the custom of bartering must have naturally arisen within it, but the stage of bartering in a market, periodically opened at a certain spot, such as is described in the San-kuo-chih, must have been the result of a gradual development. Moreover, it would be a too hasty conclusion to say that such a group was a self-providing economic community. On the other hand, to suppose that such a group was a corporation something like the guilds of medieval Europe would be absurd. Though the members of a guild suffered greatly under the oppression of its master, still no relation of vassalage is recognisable in the system. In old Japan, however, men grouped in the manner described above belonged to the chieftain of that group, that is to say, they were not only his subjects but his property, to be disposed of at his free will. As to the groups which pursued a special craft, I do not deny the existence of the practice of bartering between them. In a society in the stage of civilisation of old Japan, no one could exist without some sort of bartering, and the ruling hand was not so strong and rigorous as to be able to prohibit an individual of the group from exchanging the work of his hands with those of men of neighbouring groups, even when the lord of the group wished contrariwise. And it must be kept in mind that though a member of the group of a special profession pursued that profession as his daily business, yet he must have been engaged in agricultural work also, tilling the ground, presumably in the midst of which his house stood. Agricultural products thus raised could perhaps not cover all the demands of his family for subsistence. But, on the other hand, that all the victuals they required were supplied by barter or by distribution on the part of the chieftain of the respective group is hardly to be imagined.
A group pursuing the same occupation was of course not the only one allowed to pursue it, nor was their habitation limited to one special locality. In other words, there were many groups which were engaged in the same occupation, and those groups had their residence in different provinces. It is not clear whether all the groups pursuing the same craft were under the jurisdiction of a common chieftain. The fact is certain, however, that many groups engaged in the same craft often had a common chieftain, notwithstanding their occupying different localities. The chieftain of a group was sometimes of the same blood as the members of the group, as in the case where the group consisted of homogeneous immigrants. The chieftains of immigrant craft-groups, the number of which was very much limited in this country, belonged to this category. Sometimes, however, the chieftain of such a craft-group was not of the same stock as the members of the group under him, though the latter might be of homogeneous blood. This was especially the case when a group was that of arms-bearers composed of Ainu or Haito. These valiant people were enlisted into a homogeneous company, but they were put under the direction of some trustworthy leader, who was of the same racial origin as the imperial family or who belonged to a race subjected to the imperial rule long before. Lastly, in the case where a group was a memorial institution, it is probable that the chieftain was nominated by the emperor without regard to his blood relationship to the members of the group under him.
Summing up what is stated above at length, there were two kinds of seigneurs who were immediately under the sovereignty of the Emperor; the one was the landlord, and the other was the group-chieftain. It is a matter of course that the former was at the same time the chieftain of the serfs who peopled the land of which he was the lord, while the latter was the lord de facto of the land inhabited by himself and his clients, so that there was virtually very little difference between them. As regards their rights over the land and the people under their power it was equally absolute in both cases. The principal difference was that the right of the former rested essentially on his being the lord of the land, and that of the latter on his being the chieftain of the people. How did such a difference come into existence?
The fact that there were many landlords who were not of the same stock as the imperial family, might be regarded as a proof that they were descendants of the chiefs who held their lands prior to the coming over of the Japanese, or, more strictly, before the immigration of the predominant stock. They acquiesced afterwards in, or were subjected to, the rule of the Japanese, but the relation between the Emperor and these landlords was of a personal nature, and the right of the latter over their own land remained unchanged. Later on many members of the imperial family were sent out to explore new lands at the expense of the Ainu, and they generally installed themselves as masters of the land which they had conquered. These new landlords assumed, as was natural, the same power as that which was possessed by the older landlords mentioned above. The power of the imperial family was thus extended into a wider sphere by the increase in the number of the landlords of the blood royal, but at the same time the power of the Emperor himself was in danger of being weakened by the overgrowth of the branches of the Imperial family.
As to the chieftains of groups, they must have been of later origin than the landlords, for to be a virtual possessor of land only as the consequence of being chieftain of the people who happened to occupy the land shows that the relation between the people and the land inhabited by them was the result of some historical development. Moreover, the grouping of people according to their handicrafts must be a step far advanced beyond the pristine crowding together of people of promiscuous callings. It is also an important fact which should be taken into consideration here again that the greater part of the craft-groups consisted of immigrants. From all these data we may safely enough assume that the chieftains who were at first placed at the head of a certain group of people perhaps came over to this country simultaneously with the predominant stock, or came from the same home at a time not very far distant from that of the migration of the predominant stock itself, and that they distinguished themselves by their fidelity to the emperor; in short, these chieftains might have been mostly of the same racial origin as the imperial family, except in the case of groups formed by peninsular immigrants of later date. The increasing organisation of such groups, therefore, must have led to the aggrandizement of the power of the imperial family; but there was, of course, the same fear of a relaxation of the blood-ties between the emperor and the chieftains akin in blood to him.
Such are the general facts relating to the social and political life of Japan before the seventh century. If its development had continued on the lines described above, the ultimate result would have been the division of the country among a large number of petty chieftains, heterogeneous in blood and in the nature of the power which they wielded, and with very relaxed ties between themselves and the emperor. We can observe a similar state of things even today among several uncivilised tribes, for example, among the natives of Formosa and in many South Sea Islands. Japan, however, was not destined to the same fate. How then did it come to be consolidated?
Centralisation presupposes a centre into which the surroundings may be centralised. This centre or nucleus for centralisation may be an individual or a corporate organism. As regards the latter, however, in order to become a nucleus of centralisation, it must be solidly organised, which is only possible in an advanced stage of civilisation. For Japan in the period of which I am speaking, such a centre could create only a very loose centralisation, which could be broken asunder very easily. To have Japan strongly centralised, it was necessary for her to have an individual, that is to say the Emperor, as a nucleus of centralisation.
We have seen the process by which the predominant stock of the Japanese grew in power and influence, as well by exploring new lands and installing there men of their own stock as lords, as by organising more and more new groups out of the immigrants who came over to this country, and, perhaps, also out of a certain number of autochthons. Within the predominant stock itself the imperial family was no doubt the most influential. Most of the new landlords were recruited from the members of that family, and many memorial groups were instituted in their honour and for their sakes. Stretches of land which were exploited by these clients and on that account stood under the rule of the family increased gradually. Such an estate was called miyake, which meant a royal granary, a royal domain. The number of these domains constantly grew as time went on. Not only in the neighbourhood of the province of Yamato, in which the emperors of old time used to have their residence, but also in several distant provinces new miyake were organised. It is no wonder that they were more generally instituted in the western provinces, especially in the coastal provinces of the Inland Sea and in the island of Kyushu rather than in other directions, because it was natural that the imperial house, which is said to have had its first foothold in the west, should have had a stronger influence in those parts than in provinces close to lands still retained by the Ainu and not yet occupied by the Japanese. Still it is a credit to the power of the imperial house that in the first half of the seventh century, we can already find such royal domains in the far eastern provinces of Suruga and Kôtsuke.
The method of increasing the miyake was not limited to the exploitation only of new ground previously uncultivated. Some of the chieftains were loyal enough to present to the emperor a part of their own dominions or a portion of their clients, with or without the lands inhabited by them. Confiscation, too, was a method often resorted to, when the crimes of some of the landlords, such as complicity in rebellion, insult to high personages of the imperial family, and so forth, merited forfeiture. Sometimes there were penitents who made presents of their lands or people, in order either not to lose or to regain the royal favour. In these sundry ways the imperial family was enabled to increase its domains to a very large extent, domains which, it should be noted, were cultivated mostly by groups of immigrant people, generally superintended by capable men of the same groups who knew how to read, write and make up the accounts of the revenue.
