"Men are always forming groups; whilst, on the other hand, few ever come to anything. On this account, they fail to follow their lords or fathers, and soon come into collision with those of neighbouring villages. If the ancient prohibitions are not maintained, somehow or other innovating schemes will be formed."
Everything in the form of combination, whether nominally for good or for evil, was regarded with suspicion by the Bakufu, and all unions were therefore interdicted. Of course, the most important incident which the law was intended to prevent took the form of alliances between barons of adjacent provinces.
"(8) Marriages must not be contracted at private convenience.
"Now, the marriage union is a result of the harmonious blending of the In and Yo (i.e. the Yin and Yang of Chinese metaphysics, the female and male principles of nature). It is therefore not a matter to be lightly undertaken. It is said in the 'Scowling' passage of the (Chow) Book of Changes, 'Not being enemies they unite in marriage.' Whilst (the elders are) thinking of making advances to the opponent (family), the proper time (for the marriage of the young couple) is allowed to slip by. In the 'Peach Young' poem of the Book of Odes it is said, 'If the man and woman, duly observing what is correct, marry at the proper time of life, there will be no widows in the land.' To form cliques (political parties) by means of matrimonial connexions is a source of pernicious stratagems."
This provision was, in fact, a codification of the veto pronounced by Hideyoshi on his death-bed against marriages between the families of different daimyo. Ieyasu himself had been the first to violate the veto, and he was the first to place it subsequently on the statute book. The third Tokugawa shogun, Iemitsu, extended the restriction by ordering that even families having estates of only three thousand koku should not intermarry without Yedo's previous consent.
"(9) As to the rule that the daimyo shall come (to the shogun's court at Yedo) to do service:—
"In the Shoku Nihongi (The Continuation of the Chronicles of Japan) it is recorded amongst the enactments,
"'Except when entrusted with some official duty to assemble, no one (dignitary) is allowed at his own pleasure to assemble his tribe within the limits of the capital, no one is to go about attended by more than twenty horsemen, etc.'
"Hence it is not permissible to lead about a large force of soldiers. For daimyo whose revenues range from 1,000,000 koko down to 200,000 koku, the number of twenty horsemen is not to be exceeded. For those whose revenues are 100,000 koku and under, the number is to be in the same proportion.
"On occasions of official service, however (i.e. in time of warfare), the number of followers is to be in proportion to the social standing of each daimyo."
