Hideyoshi's administrative organization was remarkable. He created five _bugyō_; namely, a mayor of the city of Kyōto, a manager of taxation, a judicial administrator, a supervisor of the public works, and a supreme judge of civil suits. He also selected Tokugawa Iyeyasu, Uyesugi Kagekatsu, Mōri Terumoto, Ukita Hideiye, and Mayeda Toshiiye to form a council of state, called the _gotairō_, five elders, for the purpose of deliberating upon all weighty national affairs. The question of the land also received careful attention at his hands. Perceiving that, owing to faulty administration of the regulations, many irregularities had arisen, and estates were in many cases wrongly registered, he dispatched inspectors to all the provinces and caused accurate surveys and returns to be made, severe punishment being meted out to any officials convicted of receiving bribes in the execution of this office. The result was that large tracts of land hitherto improperly exempted from taxation were brought within the fiscal system. A radical change was also introduced in the manner of registering lands: hitherto they had been classed according to the monetary income obtained from them; thenceforth they were estimated according to their produce in kind, and the taxes were calculated on the basis of this new valuation. Speaking roughly, about two-thirds of the produce went to the state, the remainder to the cultivators of the land. Further, in view of the defective condition of the currency, Hideyoshi caused gold coins of two dimensions--_ōban_ and _koban_--to be struck, as well as ingots of silver, and coins of silver and copper known as the _tenshō tsūhō-sen_. In Hideyoshi's time Christianity had already obtained considerable vogue throughout the country. Oda Nobunaga had sanctioned the preaching of the foreign creed, and had built for it a place of worship, called Namban-ji, in Kyōto. But when Hideyoshi, in the course of his campaign against Shimadsu, reached Hakata, the Christian priests showed such an arrogant demeanor that Hideyoshi, enraged by their conduct, ordered that they should leave Japan by a certain day, and prohibited the people from embracing Christianity. He even went to the length of causing Namban-ji to be destroyed. Some of the converts, however, managed to conceal themselves and carry on their worship in secret. When the Tokugawa shōguns came into possession of the administrative power, the edicts against the foreign faith were strictly enforced, and steps were taken to restore to Buddhism those who had embraced Christianity. These measures were unsuccessful, however, and culminated in the Shimabara disturbances in 1637, which will be subsequently described.
