155.Akagi Castle Part1

The starting point of Takatora Todo as a castle construction master

Location and History

Takatora was seeking his Ideal Master

Akagi Castle was located in the mountain part of Kii Province what is now Wakayama Prefecture. The castle was built around 1589 by Takatora Todo who would be a well-known master of castle construction later. The castle was one of his earliest castles, so it can be seen as the starting point of his castle construction. Takatora came from Omi Province near Kyoto during the Sengoku Period when so many warlords divided the country and often battled with each other. He was well built and distinguished himself in many wars, however, his masters didn’t always survive. As a result, he changed his masters as many as seven times like an excellent business person changes one’s job several times now. In 1576, he found his fourth master, Hidenaga Toyotomi, the little brother of Hideyoshi Toyotomi who would become the ruler of Japan later.

Hedenaga was a nicely balanced leader joining his brother’s unification of Japan. Takatora was promoted by Hidenaga to one of his senior vassals and also learned many elements of the enterprise, one of which was how to build castles. He must have experienced it through many battles under Hidenaga. In 1585, Hideyoshi had conquered Kii Provence which was given to Hidenaga. Hidenaga also gave part of the province to be governed to Takatora. However, it was not easy because many local lords still didn’t want to be ruled by others, who also had guns which were popular weapons in the province at that time. One of Takatora’s answers to the question was to build his new castle called Akagi Castle.

Mountain Castle with Advanced System

Akagi Castle was a simple mountain castle with its Main Enclosure on a hill and its other enclosures on the three ridges in the north, east, and west. They are similar to many other castles built at that time so far. Takatora added advanced systems with his own ideas and experiences using the current technology. First, the Main Enclosure was basically square shaped and surrounded by high stone walls. The line of the walls was also bended elaborately to make a side attack to enemies. Its entrance was guarded by a small square space called Masugata. These features can be seen in other castles Takatora built later such as Imabari and Tsu Castles. Other enclosures were also surrounded by stone walls and placed wisely. For example, if visitors or enemies wanted to go the Main Enclosure by passing the enclosures on the eastern ridge, they had to go through three alternated entrances called Koguchi.

Takatora succeeded in governing the area around the castle. The castle probably provided relief from dangerous battles and Takatora’s authority to the local people. However, his stable governance was not done by only the castle, but also by his strict policy. He executed 160 rebels including local warriors and farmers, called Kitayama Uprising, at Tabirako Mountain Pass near the castle just after the completion of the castle. The reason for the uprising is said that they were against Hideyoshi’s nationwide land survey because the government before Hideyoshi did not recognize how much field people had. People had to pay more tax after the government survey. That was one of the realities in the Sengoku Period.

In the first 17th Century, the Asano Clan governed Kii Province. They were based in Wakayama Castle, but also used Akagi Castle as the Kitayama Uprising people rebelled again. The clan executed more people than Takatora. Akagi Castle was finally abandoned due to the Law of One Castle per Province by the Tokugawa Shogunate in 1615.

155.赤木城 その1

築城の名手、藤堂高虎の原点

立地と歴史

理想の主君を求めた高虎

赤木城は、現在の和歌山県に当たる紀伊国の山間部にあった城でした。この城は1589年に、後に築城の名手と言われるようになる藤堂高虎によって築かれました。この城自体が高虎が築城した中では初期のものとなるため、彼の築城術の原点として位置付けることができます。高虎は、京都の近くの近江国出身であり、その当時は戦国時代で多くの戦国大名が割拠し、互いに戦によりしのぎを削っていました。彼は並外れた体格を持ち、多くの戦いで武功を挙げました。しかし、彼の主君は必ずしもこの時代を乗り切ることはできませんでした。その結果、現代の優秀なビジネスマンが転職を重ねるがごとく、高虎はその生涯で7回主君を変えています。そして1576年に、4度目の主君として、後に天下人となる豊臣秀吉の弟、豊臣秀長を見出しました。

秀長は、周りとの調和を重んじたよきリーダーであり、秀吉の天下統一事業を支えました。高虎は、秀長により重臣の一人として抜擢され、事業を進めるための様々な要素について学びました。その一つが築城術だったのです。彼は、秀長の下での多くの戦いを通じて実践的にそれを学んだに違いありません。1585年、秀吉は紀伊国を征服し、この国を秀長に与えました。秀長はまた、紀伊国を統治するために、その一部を高虎に与えたのです。しかし、地場の領主たちはいまだ他者により統治されることを好まず、当時武器の主流となっていた鉄砲も多く所持していました。よってその統治には困難が伴っていました。その問いへの高虎の回答が、新しく赤木城を築くことだったのです。

最新のシステムを導入した山城

赤木城はシンプルな山城で、本丸が丘の上にあり、他の曲輪は北、東、西の三つの峰の上にありました。ここまでは、それまでにあった他の多くの城に似たものでした。高虎は、彼自身のアイデアと経験をもとに、その当時の最新の技術を使った新しいシステムを城に導入したのです。まず本丸は、基本的に四角い形に作られ、高石垣に囲まれていました。また、石垣のラインは巧みに曲げられていて、敵に対して側面攻撃ができるようになっていました。本丸の入口は、桝形と呼ばれる小さな四角い空間によって防御されていました。これらは、今治城や津城など、高虎が後に築く城にも見られる特徴です。他の曲輪群も石垣に囲まれ、よく考えられた配置をしていました。例えば、もし現代のビジターや過去には敵が、東の峰にある曲輪を通って本丸に行こうとした場合、虎口と呼ばれる食い違いになっている入口を3つ通り過ぎなければなりません。

高虎は、この城の周辺の地域を治めることに成功しました。この城は恐らく、戦いによる危険から身を守り、高虎の権威を地元の人々に示したことでしょう。しかし高虎の安定した統治は、この城によってのみ果たされたのではなく、厳しい政策も実行された結果だったのです。彼は城の完成直後に、北山一揆と呼ばれる、反抗した地元の武士や農民たちを、近くの田平子(たびらこ)峠において160人も処刑したのです。一揆が発生した理由は、秀吉が全国的に実施した太閤検地にあると言われています。秀吉以前の政権は、人々の田畑の規模を正確には把握していませんでした。検地によって、人々は多くの年貢を納めなければならなくなったことでしょう。これが戦国時代の一つの現実でした。

浅野氏に引き継がれ、一国一城により廃城

17世紀初頭、浅野氏が紀伊国を統治しました。彼らは和歌山城を本拠地としていましたが、北山一揆が再び起こったため、赤木城も使っていました。そして高虎の時以上の人たちを処刑したのです。赤木城は、最終的には1615年に徳川幕府によって発せられた一国一城令により廃城となりました。

154.Tamaru Castle Part1

The home base of Nobukatsu Oda

Location and History

Nobukatsu Oda lives in Castle as Ise Province Governor

Tamaru Castle was located in the center of Ise Province which is almost the same as modern day Mie Prefecture. The castle has a long history, which was first built by the Kitabatake Clan in 1336 during the Northern and Southern Dynasties. The clan survived as a warlord and the governor of the province until the late 16th Century during the Sengoku Period, while the castle was a branch castle of them. The castle eventually got popular when Nobukatsu Oda became the governor in 1575. He also lived and improved the castle as his home base in the same year. The reason for it was that he had been adopted as the Kitabatake Clan’s successor when the Oda Clan and the Kitabatake Clan had made peace with each other after their battles.

He is used by Rulers of Japan

Nobukatsu is one of the most difficult historical figures to evaluate fairly. He was a son of Nobunaga Oda, the ruler of Japan. He was first used by Nobunaga to take over the Kitabatake Clan. Nobunaga actually ordered him to kill his father-in-law, Tomonori Kitabatake in order to completely make the province Oda’s own. Some historians say Nobukatsu was a fool and an incompetent. For example, he failed his own invasion of Iga Province located next to Ise in 1579 and was blamed by Nobunaga.

After his real father was killed in the Honnoji Incident in 1582, he was then used by Hideyoshi Toyotomi, the next ruler. Hideyoshi used him as a stalking horse of beating Katsuie Shibata, Nobutaka Oda or subordinating Ieyasu Tokugawa to Hideyoshi. In the end, just after the completion of Hideyoshi’s unification of Japan in 1590, Hideyoshi fired Nobukatsu because he complained about moving to another territory. That was also the moment when Hideyoshi completed to take over his original master, the Oda Clan.

He is highly educated person

However, was Nobukatsu really incompetent even if he was inferior to the rulers; Nobunaga, Hideyoshi, and Ieyasu? He was finally given small territories which included Uda-Matsuyama in Yamato Province and Obata in Kozuke Province by Ieyasu. He was able to govern from the first Ise to the last of these territories smoothly. He was also a highly educated person as he was once the successor of the Kitabatake Clan, which had been a noble of the Southern dynasty. It is proven by a remaining Japanese garden called Rakusanen in Obata which he built. Then, if you want to see what he was like as a warlord, it may be a good idea to see Tamaru Castle.

Castle is finally followed by Tokugawa Clan

Tamaru Castle was on a hill near Ise Gingu Shrine, with the main portion as connected the Northern, Main, and Second Enclosures on its top. The Main Enclosure also had the three-level Main Tower. The Third Enclosure was below these enclosures and all were surrounded doubly by the Inner and Outer Moats. The three gates behind the moats and of the Third Enclosure were bent inside to prevent enemies from attacking easily. This structure would lead to a square defensive space called Masugata later. Some stone walls were built including the stone wall base for the Main Tower, but the details are uncertain. As long as you look at the castle, Nobukatsu chose a good location and built it well. However, the castle was unfortunately burned down by an arson in 1580 before he had to move to Matsugashima castle.

After that, the castle was restored by the Gamo Clan and followed by the Inaba, Todo and finally Tokugawa Clans. In particular, the Inaba Clan renovated the castle by building stone walls surrounding all the main portions. Since 1619, one of the Three Branches of the Tokugawa Family, the Kii Domain owned the castle through the Edo Period. It was based in the Wakayama Castle, so the Kuno Clan which was a senior vassal of the domain lived in the castle. The clan maintained and repaired it when it got old or suffered damage from natural disasters such as earthquakes.
