In the Azuchi-Momoyama period, Nobunaga ODA and Hideyoshi TOYOTOMI built their bases here and carried out economic reforms, and in addition, a concentration of population and economic development were seen by conducting a large-scale engineering works for the shogun (tetsudai bushin) and by forming castle towns.

The Azuchi Momoyama period (1568 - 1603) is one of the age classifications in Japan, referring to the period in which Nobunaga ODA and Hideyoshi TOYOTOMI held the right to rule Japan (Oda government, Toyotomi government).

Thereafter, using the fact that Yoshiaki had never officially been dismissed from the post of Seii taishogun as a pretext, movements did arise in various provinces to restore the bakufu to power, but against the momentum of the new governmental structure created by Nobunaga and Hideyoshi TOYOTOMI, such efforts were entirely fruitless, and so the Muromachi bakufu--and the Muromachi period itself--is considered to have ended at the point Yoshiaki was driven from Kyoto.

From the fifteenth century to the sixteenth century, the Kakizaki clan, who was growing to become the feudal lord of the southern Oshima Peninsula by unifying Watari-to, was recognized as to the right of dominion and trade in the Ezo territory by Hideyoshi TOYOTOMI and Ieyasu TOKUGAWA and thus became independent from the Ando clan in both name and reality; and the Kakizaki clan changed its name to Matsumae and was elevated to Daimyo (Japanese feudal lord), by which Watari-to became Japanese in Edo period.

Especially before gekokujo (an inverted social order when the lowly reigned over the elite) became common, such a point of view dominated and thus, like Hideyoshi TOYOTOMI in the Sengoku period (period of warring states) (Japan), a person originating from farmers or from a status not of samurai status could not admitted as bushi by definition.

One view on the end of the Sengoku Period, it was 1576 in which Nobunaga launched at Azuchi and jumped to "tenkabito (the ruler of the country)," and in another view, it was 1590 in which Hideyoshi TOYOTOMI made the Gohojo clan surrender, resulting in the completion of the military activities for the unification of the whole country.

During the Sengoku period (period of warring states) (Japan), the Ichien chigyo (complete proprietorships) by the daimyo (Japanese territorial lord) in the Sengoku period was realized and shoens lost substance increasingly and disappeared finally with the nationwide land survey by Hideyoshi TOYOTOMI.

These drawbacks were exposed at the end of Hideyoshi TOYOTOMI's time in power.

In the Azuchi-Momoyama period, Yi Dynasty Korea sent Chosen Tsushinshi to Hideyoshi TOYOTOMI for checking whether he had an intention of sending his military troops to Korea.

As a result of heinobunri (a separation of the warrior class in this domain from the soil) (Sword Hunt) and the confirmation of land ownership (Taiko-kenchi (the land survey by Hideyoshi TOYOTOMI), which had been implemented by Hideyoshi TOYOTOMI, the style of connection called the soson finally disappeared, and there emerged early-modern villages that survived in the Edo period.

However, they were gradually deprived of their lands by the daimyo during the Sengoku period (period of warring states) and finally they lost all lands through taiko kenchi (the cadastral surveys conducted by Hideyoshi) conducted by Hideyoshi TOYOTOMI.

In the Azuchi-Momoyama period, chigyodaka (a stipend in terms of rice production of the fief) was represented by the volume of rice to be supplied; that is to say, by the unit of 'koku' (also called kokudaka), which was organized during the Taiko kenchi (the cadastral survey of Taiko) conducted by Hideyoshi TOYOTOMI.

At the end of the Sengoku period (period of the warring states) (Japan), Nobunaga ODA, Hideyoshi TOYOTOMI and others were strongly against the jisha seiryoku and fought many vicious battles.

Katanagari (written as 刀狩 or 刀狩り) was a policy of heinobunri (separating warriors and peasants) which deprived those in the peasant class of their privilege of wearing swords, which highlighted the policy enacted by Hideyoshi TOYOTOMI through the katanagari edict (at the same time, pirate ship interdiction) issued on August 29, 1588 in the Azuchi-Momoyama period (The first person who executed katanagari was Katsuie SHIBATA.

When involvement in situations in the continent became inevitable as a result of the establishment of diplomatic relationships by opening Japan in the last days of the Edo and the Meiji periods, same as commanders at the time of war were reminded of sankan-seibatsu (the conquest of three countries in old Korea), dispatch of troops by Hideyoshi came to be closed up and many came to consider advancing into the continent was conduct following Hideyoshi's wishes.

During the Warring States period, Zenso YAKUIN, a descendant of the Tanba clan, served Hideyoshi TOYOTOMI as a close adviser and was appointed as the Yakuinshi by Emperor Ogimachi as an imperial order so as to reconstruct the Seyakuin that had lost its substances.

The words "Kishu Seibatsu" or "Kishu-zeme" refer to the conquest of Kii Province by Nobunaga ODA and Hideyoshi TOYOTOMI in the Sengoku period (period of warring states) (in the Azuchi-Momoyama period).

Shigeuji OIKAWA survived as a retainer of the KASAI clan although the Shigetane family line declined, but later, during the time of Hideyoshi TOYOTOMI, the KASAI clan was destroyed by Hideyoshi; all the family became ronins (masterless samurai), and some of them joined Kasai-Osaki-ikki (the revolt of the former retainers of the Kasai and Osaki clans).

According to Nisshu Shonai Gunki, there is an entry stating that Mitsunari ISHIDA or Ieyasu TOKUGAWA told Tadatsune, who had returned from Korea after the death of Hideyoshi TOYOTOMI, that Tadamune IJUIN was thinking of rebellion, but there is no other historical evidence of the same era to prove it.

Even though Ieyasu was believed to be an agricultural fundamentalist, it is pointed that Ieyasu was, in effect, likely to pursue the growth-oriented economic promotion because he actually lived in the same period as Nobunaga ODA and Hideyoshi TOYOTOMI, and witnessed Nobunaga's economic promotion policy by thorough deregulation.
