“I said JUST eleven!” Professor Miura said, looking at Chris from the corner of his eyes again.
Professor Miura is a specialist in castle architecture at Hiroshima University. Chris Glenn, the famous radio DJ and samurai expert in Japan, was interviewing him about Nagoya Castle’s gates and watch towers. It was November 15th and I was attending the lecture.
The number eleven, Professor Miura mentioned, indicates the number of watch towers in Nagoya Castle. Watch towers were the buildings for looking out, the strongpoints of defense, and arsenals before the Meiji Era (1868).
“I said JUST eleven!” Professor Miura said again. The whole room was filled with giggling. You know the reason if you have read my former article (Nagoya Castle’s Castle Gates and Watch Towers 1: Death Box). Actually, almost the same thing had happened a few minutes previously when he mentioned the number of castle gates in Nagoya Castle. He said “I said JUST six!” at that time.
“Why did you say JUST eleven?” Chris asked him, rolling his eyes. Professor Miura nodded approvingly and said, “There were more than 80 watch towers in Hiroshima Castle and Okayama Castle. Kumamoto Castle and Himeji Castle had over 100 watch towers! Therefore, the number of watch towers in Nagoya Castle was extremely small.”
Actually, two more watch towers were planned to be built in Nagoya Castle. But Osaka Castle, which was the enemy’s stronghold, fell in 1614 before all the watch towers were completed. That newfound victory is why the foundations for those watch towers remain unbuilt-on.
Interestingly, the designs of the watch towers in Nagoya Castle are all different. Their size, style, shapes of roofs and windows and everything are diverse. Professor Miura gave a funny example to illustrate this uniqueness. “Imagine all the fighters in the Japan Self-Defense Force are different.” Oh, I see…
One big difference between Nagoya Castle’s watch towers and those of other castles except for its diversity is their largeness. Each tower is as big as other castle’s main buildings (donjon). After the lecture, the participants had a rare opportunity to tour one of the watch towers. It is called Seihoku-Sumi-Yagura, and used to be the main tower of Kiyosu Castle, which was the castle of Oda Nobunaga, one of the most powerful feudal lords in the Age of Provincial War (the 16th century). That is why the watch tower is also called Kiyosu Yagura.
Kiyosu Castle was demolished and its main tower was reconstructed as one of the watch towers in Nagoya Castle at the beginning of the 17th century, when Nagoya Castle was built. I do not know the reason but the present main tower of Kiyosu Castle is a replica of Inuyama Castle’s main tower…
Although the number of watch towers is very small, the scale is more impressive than other castles due to the capacity of Nagoya Castle’s watch towers. Moreover, Nagoya Castle had a series of huge roved corridors which surround the main enclosure of the castle. It was called Tamon-Yagura and was also a gigantic store-room for weapons and armor. The width of the corridors was about six meters and the dimensions were equal to more than 300 watch towers from other castles. Unfortunately, this has not been rebuilt yet after it was burnt down by air raids during the Second World War.
I wrote in my previous article that enemies could not enter through the castle gates or other places. The reason is the existence of this huge series of corridors. It was impossible to break into the main enclosure of the castle through the strongest gates and the roofed huge corridors at that time. Actually, the corridors had a disconnected fireproof compartment, and the idea of fire protection was introduced to castle architecture for the first time in Japan. Not only its military preparedness but also the concept shows that Nagoya Castle was the most advanced architecture in Japan in the 17th century.
Professor Miura shouted, “Nagoya Castle should be rebuilt to its original style including Tamon-Yagura! It is Nagoya City’s duty!” Yeah! I would like to see the beautiful appearance of Nagoya Castle with the legendary Tamon-Yagura!
