Busetsu Castle / 武節城
The castle ruins descend like steps with the Honmaru, Ninomaru and Sannomaru constructed one below the other in a line, forming a Renkakushiki formation. This suggests a weak formation, as the important Honmaru baily is exposed on three sides, however the area is surrounded by numerous kuruwa baileys affording adequate protection. Busetsu has 16 main baileys, and over 30 smaller baileys. A swordsmith forgery was located on the site of one of the lower baileys.
The amount of earthworks and the quality of the early 16th century manual labor is amazing. Having large numbers of baileys carved into the hillside means lots of kirigishi, artificially created cliffs and steep slopes. A large Karabori, dry moat, winds its way through the site, linked to smaller dry moats carved into the hill itself. These remain in form from over 500 years ago! The site of the monomidai tower and noroshi smoke signal tower above the Honmaru now houses a small shrine. The Honmaru bailey is vacant, but is used as the shrine’s carpark. The Ninomaru bailey is also vacant, but the San-no-maru is now a vegetable garden. One of the larger baileys has long been used as graveyard, another as a gate-ball field. Others are gardens and even private housing on the castle site. Most are now overgrown with trees and bamboo.
The site hasn’t been maintained very well, and although a road has been built leading to the Honmaru, although it does not follow the original path in and out of the castle. It is thought the original route led from the Jokamachi, castle town below, to the lower corner of the San-no-maru bailey.
The castle has not yet undergone any research excavations, and one of the reasons is because it is dubious much would be revealed. The Honmaru and Ninomaru are now vacant, but during WWII were used as potato growing fields, which appears to have been the reason for the important soseki building foundation base stones having been dug up and removed. I discovered piles of large stones, which appear to be both soseki foundation stones and possibly roof weighting stones in the Ni-no-maru bailey. On March 30, 1984, the ruins of Busetsu Castle were designated as a Toyota City (former Inabu Town) Historic Site, along with nearby Busetsu Kojo.Profile by Chris Glenn.
Fukuzuka Castle (Mino) / 美濃福束城
Hida Castle (Omi) / 肥田城
Hijiyama Castle (Iga) / 伊賀比自山城
All that remains of the castle are the original earthworks, dorui, or earthen embankments around leveled compounds, Horikiri trenches cut into the mountain to prevent enemy advances, and kirigishi, mountainsides shaved back to increase the angle and prevent infiltration. It is exceptionally overgrown, even in winter. This was real Indy Jones jungle tour trekking. We walked a total of 6km, but according to the health meter in my mobile phone we climbed the equivalent of 66 flights of stairs!Profile by Chris Glenn (edited by ART).
Himega Castle (Mikawa) / 三河姫ヶ城
It takes about 6 minutes by the proper stair lined route, 15 plus minutes if attempting to climb through the bamboo and trees freestyle up the steep side (i.e Attacking Warrior Route).
The main part of the castle at the top has been cleared of trees, and the view was good. The two main baileys are the Ni-no-kuruwa second bailey containing a small Inari shrine complex, directly above this, separated by dorui earthen embankments and a small koguchi entrance, the Hon-kuruwa, main bailey, about 30m wide. An obikuruwa, a smaller thinner bailey surrounding the mountain is supposedly found at some point, as well as a horikiri trench however I could find no trace of either. The Hon kuruwa has a small marker stone stating “Historic Site Himega Castle”. The Tomei Expressway can be seen directly below, and beyond that, a fine view of the Mikawa and Okazaki area.Profile by Chris Glenn (edited by ART).
Kaminogou Castle (Mikawa) / 三河上ノ郷町城
Mibuno Castle (Iga) / 伊賀壬生野城
One of the most fascinating points of interest regarding this castle are the 2-4 meter high, thick dorui earthen walls surrounding it. Most Sengoku period castles have the same earthen embankments piled up to make the protective walls, however Mibino castle’s dorui feature large gaps — almost like battlements — around the top. Exactly what these V-shaped spaces were for, remains unknown, although speculation includes “stone dropping” and teppo matchlock firing spaces.
My own thoughts are that there may have been low wooden shield-like walls along the upper, outer edge to allow firing positions for gunners and particularly archers, with their longer bows standing in the sunken sections to remain partially covered, but be forward enough so as not to be hindered by the walling. Again, this is only my speculation. On the north western corner is a slightly thicker segment of dorui. This is slightly hollowed out with a 60cm deep, 2 meter diameter dish, and it has been suggested that it may have been the noroshi-dai, or smoke flare base.
Mibino Castle is currently undergoing preservation works by the Iga Ueno City Culture and History division.Profile by Chris Glenn (edited by ART).
Momochi Tamba Castle / 百地丹波城
East of the temple is the shukaku, or main enclosure, which forms an L-shape with koguchi gates to the north and south. The kuruwa is around 70m long, and 40m wide, This kuruwa is surrounded by high, thick, well preserved dorui (earthen walls), about 4m high and 5 to 10m thick. The tops of these thicker dorui are flattened into spaces that could have supported basic yagura, or monomidai watchtowers. These earthworks are very impressive. The remains are almost complete, and the main enclosure’s surrounding earthworks, moats, wells, etc. are quite spectacular.
The northern koguchi gateway is a 15m long and narrow path between high dorui, while the larger, wider southern koguchi appears to have been the main entranceway. To the east of the main kuruwa is another small gap in the dorui where a wooden bridge once probably crossed the deep, 5m wide karabori dry moat running north-south.
This karabori separates the main kuruwa from the larger, flatter, square shaped B Kuruwa around 50m long and 40m wide, which is overlooked by a smaller, 30x30m square shaped A Kuruwa a little further up the hill. Most people wouldn’t realise there is more to the castle than the main kuruwa, and the other sections are a little overgrown.
Some people consider this a toride, a fortress rather than a castle, but looking at the scale and the amount of work put into the creation of this site, I’d say it is a castle, more so than a simple toride fortress.
The castle site is most impressive, and exploring the area is also enjoyable. When you do go, remember to always be on the lookout,….you never know where a ninja might be hiding!Profile by Chris Glenn (edited by ART).
Nishiohhira Jin'ya / 西大平陣屋
Located opposite Senkou-ji Temple in Okazaki, the site of the Nishi Odaira Jinya now contains an Inari Jinja shrine. The gates and walls have been recreated, but unfortunately no other structures have been rebuilt.Profile by Chris Glenn (edited by ART).
Oka Castle (Mikawa) / 三河岡城
There is next to no signage. The road leading to the actual site is too narrow for a vehicle, and there is no parking or U-turn space either. Along the road to the south of the site is a nagayamon (long gate) like farmhouse structure, there is room for cars to park opposite this, and it’s a short walk to the site. First you’ll see a small shrine and explanation board to your left and the previously mentioned forest of bamboo filling the 3-4m drop to your right. Proceeding behind the houses, one will see the dorui and former baileys amongst the tall bamboo.Profile by Chris Glenn (edited by ART).
Okayama Jinjiro / 岡山陣城
Hirayamajiro make use of both a hill or small mountain and the flat lands around its base. There are also Jinya, small castle like defensive positions held by low-ranking Daimyo and high ranked Hatamoto, and there are Jinjiro, literally “fortified battle camps”. One of the largest Jinjiro was Okayama Jinjiro in Ogaki City, Gifu Prefecture.
Unfortunately, the main kuruwa was used by Ogaki City to situate a mains water supply tank, while the other kuruwa baileys are used as graveyards and farmland. Some of the moats and dorui, as well as some sections of kuruwa can still be seen to this day, although the aforementioned water tanks and graveyards have changed the site and damaged historical earthworks.Profile by Chris Glenn (edited by ART).
Unuma Castle / 鵜沼城
The castle ruins are located on a small rocky hill (Shiroyama) near the Inuyama Bridge on the Meitetsu Line. There used to be an inn and restaurant called Shiroyama-so, but it was closed due to a major fire in December 1972 in which a number of people were apparently killed. The ruins were removed in 2002. The mountain itself is owned by Kakamigahara City, and plans are underway to develop it into a park by 2023, but the foot of the mountain is currently private property and cannot be accessed.Profile by Chris Glenn (edited by ART).
Yamanaka Castle (Mikawa) / 三河山中城
To the east and below the main and second baileys is the 20-metre-long square shapedHigashi-guruwa bailey , which is key to the castle’s central defences. Below it, on two ridges stretching to the north and east, are terraces of baileys. Each line of terraces has dry moats at the choke points and twisting paths to form enemy obstacles on approach.
Just below this eastern bailey is a semi-circular Umadashi! Umadashi were an effective defensive barrier and compound complex built in front of castle gates, used as a screen to facilitate cavalry charges and attacks during times of siege. Like a barbican gate system, the Umadashi worked like an airlock for a castle, allowing attack parties to sally forth and safely return, without letting the enemy in.
They served as a first line of defense, protecting the main gates. It’s only a small Umadashi, but to see it used in such a position, and so high up the mountain was fascinating!
Yamanaka Castle’s multiple (at least 8!) northern facing tatebori, vertical trenches up the side of the mountain, and horikiri, deep V shaped trenches preventing enemy advances across mountain ridges, (lost count of how many) are quite impressive.
Like most yamajiro, Yamanaka Castle makes very good use of the natural defences of the mountain, augmented and strengthened by the ingenuity of the samurai and their earthwork skills. Naturally, the top of the mountain was cut flat to form a circle.
Parts of the mountainside are also cut away to form Obi-kuruwa, like flat paths around the mountainside. These were created not only to create more space, but also to make the hillside steeper and more difficult to climb. These steep slopes, called a kirigishi, are a most important defensive feature. Most people only see the obi-kuruwa baileys without realising that they are the result of a kirigishi being formed. At Yamanaka Castle, the easily recognisable Obi-kuruwa are very visible. Walking around the narrow ring like paths, you can see how difficult it would be to climb up the bank and how easy it would to shoot arrows and matchlocks in defense from above.
Yamanaka Castle has played an important role in history and boasts links with the Matsudaira, Tokugawa, Imagawa and Sakai clans. It is easily accessed, relatively easy to climb, is being maintained slowly but surely, and being the largest mountain castle site in Aichi Prefecture, it’s a must-see.Profile by Chris Glenn (edited by ART).
