Azuchi Castle Innovations

From Castles in Japan, by Morton S. Schmorleitz (Tuttle, 2011), Kindle Loc. ~830ff:

Azuchi Castle had several distinct features that differentiated it from its predecessors. Its massive proportions and the use of stone as a major building material, as noted in an earlier chapter, were to provide protection from the most destructive firearms available at that time. Other innovations such as the use of high towers and the location of the castle on a hill rather than in mountains with dense vegetation, were also related to a change in the tactics of warfare. These changes made guns an extremely effective defense because the enemy could be seen a long way off and met by gunfire precisely directed from the height of the donjon.

Just as Azuchi Castle was the prototype of the present-day relics of feudal times, the castle town created by [Oda] Nobunaga outside the castle walls was the prototype of a new kind of castle town in general. He had built quarters for his various soldiers and retainers but they were slow to occupy them, and it was two or three years before the town became fairly well settled. (Note: By 1582 the population had reached about 5,000.) At the same time, he made conditions attractive for tradesmen and artisans so that the town would be supplied with the necessary commodities to make it prosper. In 1577 Nobunaga issued a town charter stating that Azuchi was to be a free-market town with no taxes levied on sales or purchases. All merchants traveling along the Nakasendo had to seek lodging in the town when passing through, there were to be no taxes on building or transportation (except in time of war), and in the event of cancellation of debts in the province, debts owed to the town's residents would not be included. These concessions to tradesmen were made to attract money to the town, but the motive was more political than economic. With free trade, goods flowed from all parts of the country to the population and market centers, thus increasing the wealth of the cities and in turn the lord of the area. At the same time, the roads were improved to facilitate the movement of goods, and in time of war the same roads could be used to move troops. Free-trade practices also attracted skilled artisans whose talents could be used to make the tools of war.

It was during this period that Jesuit missionaries arrived in Japan and received encouragement from Nobunaga, who regarded them as a rival to Buddhism for which he had little use. When Father Gnecchi Organtino and some other priests visited Nobunaga at Azuchi, Nobunaga was so flattered that he offered the Jesuits a building site for both a church and a house; the missionaries were only too happy to accept.

After Akechi Mitsuhide killed Nobunaga at Kyoto on June 21, 1582 he marched to Azuchi, took over the castle, and distributed gifts from Nobunaga's treasury to likely supporters. (Note: Akechi is said to have treated the missionaries well.) He did no harm to the castle, but Azuchi nevertheless met its downfall shortly thereafter. It is known for certain that the fortress burned to the ground, but by whom is open to controversy. One popular and often repeated story is that Nobunaga's son, in a fit of rage, grief, or perhaps both, put the castle to the torch. Sansom acknowledges the story, but indicates that looting townspeople probably were responsible for the fire. Still another version says that the tower was destroyed by Nobunaga's adversaries. In any case, the castle burned, leaving only the stone walls, moats, earthworks, and tower foundation (Fig. 23).

The town of Azuchi is now a country village populated by people (some of whom are direct descendants of Nobunaga) who till the land, fish in Lake Biwa, and are proud of their history. At one time they wanted to rebuild the castle donjon but the idea was abandoned for several reasons including lack of funds. Also, the remains of the castle have been declared a special historical relic, and the Committee for the Preservation of Cultural Assets is reluctant to allow construction of a new donjon because of possible damage to the ruins. In addition there is some question whether reliable plans and drawings exist from which a reasonable facsimile could be built. Proponents of the project claim that drawings of the original castle exist and are the property of a temple at the foot of Azuchiyama, but the only known evidence of drawings is a sketch of the exterior on a scroll hanging in the temple.
