Is this water castle? An explanation of its history, a summary of its history | One of the greatest defense works in ancient Japan
Is this water castle?
Ancient defense construction work between Mizushiro and Kasuga City, Dazaifu City. This huge earthen fort built in the 7th century is one of the largest civil engineering projects in ancient Japan, with a total length of 1.2 km, a base width of 80 meters, and a height of 10 meters.
The origin of the name “Water City” is its unique structure. However, the defense ability of the castle river is not increased, and the defense ability is also important. In front of Mizuki, it was designated as a national special historical site, and it was a historical site where military equipment was developed, and ancient Japanese defense techniques were exhibited at international events.

Historical background of Mizuki Castle construction
The Battle of Shirae and the Japanese Crisis
The Mizuki Castle was built in 663 during the Battle of Baijiang. During the current military role, Japan’s 100 military forces were disastrously defeated in the Tang Dynasty. In this place, the lost envoy arrived at the Japanese government and invaded Tang Xinluo.
The defeat of Shirajiang was a failure on a scale that had occurred during the wars in foreign countries in the history of Japan, putting the nation in danger and threatening its survival. The Imperial Household’s rapid start-up of the defense system and the construction of the Mizuki Castle are one of the most important measures.
Emperor Tenji’s defense policy
After the Battle of Hakue, Emperor Tenji promoted an aggressive defense policy. In 664, while in other provinces, Ikiwa and Tsukushi Sanchi were built as sentries (guards in advance) and Japanese flag towers were built, and in 665 they were rebuilt as Asahi-style mountain castles – Ono Castle.
Mizuki Castle was located along the front line with minor defensive construction, and the defense line was located at the rear of Dazaifu. Ono Castle was built in Lushan District, and Mizuki Castle was designed to be the first defense line on the plains.
Dazaifu defensive key
Dazaifu was the most important center of diplomatic peace and defense in ancient Japan. It is the gateway to exchange between China and China, and is also the administrative center of the Kyushu region. The Mizuki Castle was protected by Dazaifu, and the Hakata Bay area was invaded by construction and defensive works.
Mizuki Castle’s geographical location has important strategic implications. After construction, the narrow area between the Mikasa River and the Wagyu Kubi River was completely blocked, and the main road leading to Dazaifu and Hakata Bay was completely blocked.
Mizuki castle construction technology
Hijikata engineering structure
Mizuki Castle’s earthworks are not easy to use, and the construction of advanced civil engineering engineering techniques has been completed. Archaeological excavation mission completed as follows:
Basic structure:
- Fixed base for opening ground
- Clay construction method for pottery, quick replacement clay Wasako
- Strength of fused wood during local process
Hijikata process horizontal cut surface structure:
Hijikata’s horizontal-cut planes are shaped like ladders, one side of Hakata Bay (northwest side), one side of Hakata Bay (northwest side), one side of Dazaifu (east south side), one side of the land. These types of designs can be used to prevent existing effective forces from attacking, and also to act as effective allies.
护城川统
Mizuki Castle’s most famous special expedition was the river on the side. In fact, it is located on one side of Hakata Bay, with a total area of 60 meters and a total area of 4 meters.
Abilities below:
- Physical barrier: Obstruction by enemy
- Hill hardening: Foundation for fixing earthworks
- Water source guarantee: Water source for use during defense period
- Visibility guarantee: Early arrival of enemy movement
The water level of the Mikasa River comes from the water source of the Mikasa River, and it is designed to ensure that the water level is constant.
Wood control system
Wooden control road for earthwork construction in Mizuki Castle. This is the perfect defense system since the Mikasagawa water gate, the water flow that guaranteed the peace period, and the water barrier during the war.
In 1962, the excavated wood control pipe was a large wood pipe with a diameter of approximately 2 meters, and was considered an important cultural object in advanced civil engineering engineering technology at the time of construction. Right now, you can see the exhibition in Dazaifu, where you can see part of the water canal.
Building water conduits activities
The demand for construction of water conduits consumes a large amount of manpower. 《Japanese Book》 Record, August 664, “Tsukushi Chikuchiku Daike Water Storage, Famous Water Channel.”
The number of researchers and engineers spent hundreds of thousands of hours on the construction of the water culvert. When we think about it, Japan’s population and science and technology level are at the same level, and this is a large-scale project with national resources for one operation.
The history of water conduits
Ancient effects
After the construction of the water conduits, you will be able to use the real force. Because of this, the invasion plan of the new Tang Dynasty army was finally realized. However, the existence of Dazaifu’s defensive image was created by Kazutoshi Mizunao.
In the 8th generation of Kōgen, Japan’s Yoshinro’s original system was Hijaku Hiroaki, and Mizuki’s defensive ability was repeated. In addition, there is a connection between the government and Hakata government roads, which are important transportation hubs for missions.
Changes since the Middle Ages
Since the Heian period, the importance of Mizuki military affairs has gradually declined. Hijikata process step by step, Kawaya Kōjo covered flat. During the Middle Ages, the road was renovated on Mizuki, and the Zhouyan area was used for agricultural cultivation.
During the Jiang Dynasty, Mizuki’s main presence was in the region, but the original appearance was different. Information from Mizuki Mizuki, a scholar of the Fukue domain, who wrote his work Chikuzen Province Wind and Land Records.
Since the modern era, new innovations and protection
Annotations from a historian and Japanese archaeologist who admired the beginnings of Mizuki Castle during the Jimei era. In 1922, Mizuki Castle was designated as a national historical monument, and in 1953, it was designated as a special cultural historical monument.
In 1962, a large-scale excavation was completed, and the construction of Mizuki Castle was completed. This is the turning point in Mizuki Castle’s research, and since then, the research has continued to move forward.

The castle gate is uniformly designed on the east and west sides of Mizuki Castle. The location of the eastern gate has been confirmed by the archaeological excavation, and the information board has been set up.
The construction of an ancient transportation system, where one official road was pierced by Mizuki Castle, was what I imagined.
Woodwind exhibition
In 1962, the first stage of the woodwind was preserved and exhibited at the Dazaifu Exhibition Hall in Dazaifu City. The giant woodwind, with a root diameter of about 2 American, is now a rare artifact of civil engineering technology advanced over 1,300 years ago.
Viewpoint
Due to the construction work on the site of Mizuki Castle, you can see the distant view of Hakata Bay and Dazaifu. Haruharu’s Hikori, who had a direct view of Hakata Bay, was able to sense the true feelings of the people who had built Mizuki Castle, and had the effect of blocking the invasion of Hakata Bay.
When the sun sets, the scenery is especially lost, and this place is the place where the sun shines.
