I think that the bast way to feel what Odawara Castle was during the Sengoku Period, would be to wak the So-gamae structure. Therefore, this article will show you how to walk around the So-gamae in the current Odawara City.

Rare Remaining So-Gamae structures on Plain Area

Unfortunately, there are only a few remaining structures of So-gamae on the plain city area. First of all, it might y be better to walk the old Tokaido Road to the east. The starting point would be Matsubara Shrine, or a rest station called “Odawarajuku-Nariwai-Koryukan”, which are located at the center of the old transportation hub of Odawara.

It would be more comfortable to go on Kamaboko Street, where there are many traditional Japanese fish cake (which is called Kamaboko) shops are located, which is also similar to the route of the old Tokaido Road during the Sengoku Period. If you walk along the street for a while, you will eventually reach Hojo Inari Shrine. The shrine was built by the Hojo Clan and at the southeast corner of the So-gamae structure.

The Hojo Inari Shrine

If you turn left to the north of the shrine, you will soon find the ruins of Edoguchi-mitsuke (which means the gate to Edo). The gate was the eastern entrance of Odawara Transportation Hub during the Edo Period. It was also the Sannoguchi Gate of the So-gamae structure earlier on. Therefore, the partitions of the gate were used until the end of the Edo Period.

In addition, there is also Sanno Shrine, which is little far from the gate ruins, which was a defensive position of the Hojo Clan outside the So-mgamae during the Battle of Odawara. The only direct fighting during the battle happened at this site.

If you go on the path beside the gate ruins, you will eventually arrive at one of the few remaining structures of So-Gamae in the city area. It is called, Renjoin Temple Earthen Walls, which is about 100m long and about 3m high. It was originally set with a moat and more defensive than this single unit. You will see a large dent on the walls, which was caused by the Odawara air raid in 1945 during World War II. The ruins had a long history through the multiple periods.

Remaining Structures on the Hill Areas

An easy way to the So-gamae structure on the hill area is to go on the opposite street of a park, called “Medaka-no-gakko”. The street will go up on Yatsu Hill, one of the hill areas behind the Odawara city area. You will eventually find the ruins of Shiroshita-Haridashi. Haridashi refers to the overhanging part of the So-gamae structure. The defenders could have lookout point of the attackers and could counterattack the side from the site. The remaining structure is the base of the overhanging part. That’s why the line forms a right angle.

You can also look around the remaining dry moats along the hill. However, most of them are currently farms now, where visitors are not allowed to enter.

The dry moats which have become farms

If you continue to go along the street for a while, you will eventually encounter a three-way intersection. Turn right at the intersection, then you will be able to travel on the So-gamae structure easily.

The three-way intersection

After a while, you will be at Yamanokami-Horikiri. Horikiri refers to a ditch separating a hill in order to avoid the enemies from attacking through the hill. If you go to the bottom edge of the Horikiri, you will find the dry moat of the So-gamae structure touching the Horikiri at right angles. However, the moat is much deeper than the Horikiri. That means the enemies that fell inside the moat, would not be able to invade the Horikiri easily.

Next comes Inari-mori (which is the town name). At this site, the earthen walls and dry moats of the So-gamae makes a dent inwards along the natural terrain. The outside of the depression looks like an isolated island. The Hojo Clan also built earthen walls on the island in part to not allow enemies to stay there. This site is one of the most intact parts of the So-gamae structure. The moats managed to keep their original conditions of about 10m deep and over 50-degree slant. This is probably why the visitors are kept out from the moats by ropes and poles.

Large Ditchies of Komine Okane-no-dai, Highlight of So-gamae Structure

The northern part of Odawara City is surrounded by the three hill areas: Hachimanyama, Tenjinyama, and Yatsu. Komine Okane-no-dai hill is part of the Hachimanyama hill area and the highest among the areas. Therefore, the hill was the most important spot for the Hojo Clan in terms of protecting Odawara Castle from invasion. The clan eventually separated the hill by building three ditches. If you walk from the Inarimori Ruins along the So-gamae structure, you will reach the intersection to the three ditches. If you turn right, you will be at the western ditch, left to the eastern ditch, or if you keep going straight, it will lead to the central one.

The intersection to the three ditches

The western ditch is at the outermost area on the hill, which was originally over 200m long, but is now only 150m long. It was built just before the Battle of Odawara. The ditch seems to get shallower and gentler compared to the original condition. However, if you look at the bottom of it, you can still see something that resembles partitions, which may be the traces of the Shoji-bori system. The edge of the ditch is still connected to the moat of the So-gamae structure.

The bottom of the ditch

Next comes the central ditch, which was built at the same time as the western one. The bottom of the ditch is now used as a modern road. You can still see some of the earthen walls around it remaining. A connecting road between this ditch and the eastern ditch still exists.

The central ditch

You will finally arrive at the eastern ditch, which has been developed as a park. You can easily walk the bottom of it. This ditch is the most intact one among the three ditches, which is 280m long and 25 to 30m wide, the same as the original conditions. It is currently 8 to 10m deep, but it was originally about 12m with the Shoji-bori system. Its slant is about 50 degrees, which may be the same as original one, too. The bottom of the ditch is not straight but rather curved, which made it difficult for enemies to walk through smoothly.

Where is the goal of the So-gamae?

You will eventually go down on the hill to the New Moats and Earthen Walls of the Outer Third Enclosure. This place is where Ujimasa Hojo launched the constructions of the So-gamae structure. You can see a great view to the west from there, including Ishigakiyama Mountain where Hideyoshi Toyotomi built his Ishigakiyama Castle during the Battle of Odawara Castle. There is another interesting story where the Hojo side was very surprised to see the completion of Ishigakiyama Castle after all the trees around were cut down, called “Ichiyajo” which means “one night castle” (a castle that only took one night to build). However, the story may be doubtful because the castle ruins can clearly be seen from the site. In addition, please be mindful that the site closes at 3:00 PM, which is much earlier than other historical sites.

You will next walk down to the Tenjinyama hill area. This area also has walls of the So-gamae, called the Earthen Walls, at the west of Denjoji Temple. The walls are located in front of the elevated railways of the Shinkansen (bullet train) and used as a graveyard. If you look up the site from below, you will realize this structure uses natural terrain as well.

Looking up the walls

After returning to the city area, you should also check out Hayakawa-guchi Ruins (Guchi means entrance or route), one of the few remaining items of the So-gamae structure on the plain area. The Hayakawa-guchi entrance was the front line to the west, where the Toyotomi troops attacked from. Therefore, the entrance was fortified heavily by doubled earthen walls and moats. If you enter the ruins, which have been developed as a park, you will eventually find that the park is sandwiched between the remaining doubled walls.

The Hayakaga-guchi Ruins

Other than that, you will be able to find other remaining earthen walls of the So-gamae structure, which are used as the bases of the modern residences along the seaside. If you find one of them, you will be able to understand that these structures were built on such a place and are still intact for the modern facilities to use. This will conclude the tour of the So-gamae structure.

This base of the modern residence uses the earthen walls of the So-gamae structure (its stone walls were probably added later on)

Nakanokuo, Pivot of Defense

Over the dry moat, the other major enclosures of Nakanokuo (the enclosure No.4 & 5) and Onokuo (the enclosure No.6 & 15) follow and are all divided by other dry moats crosswise. In particular, you should check out Nakanokuo (the enclosure No.5), over Nakanokuo (the enclosure No.4). To reach the enclosure, you need to go out of the Main Enclosure, go through the right lengthwise dry moat from the front, and enter the second crosswise dry moat. The bottom of the moat is not flat, but has two tiers, so you also need to climb to the upper tier.

Then, you will face huge vertically cut cliff of the enclosure like a thick column and need to walk around to enter. If you were an enemy, you must have been attacked by the defenders from above until then. The entrance path is altered by thick earthen walls as well, just like a palace gate made of soil. This enclosure might have been pivotal to the defense in the castle.

Amazing Dry Moats

Both the lengthwise dry moats outside the plateau are amazing. The dry moat on the left side from the front (the western side) is called O-Horikiri or the Large Ditch. It is about 17m deep and was about 7m deeper than now according to the excavation. The collapsing volcanic ash has been filling the bottom of the moat naturally. However, it is still enough for us to understand how great the warrior’s work for the moat was.

The dry moat on the right side is also surprising. The cut section of the outside enclosure is still vivid making us understand how hard their work was!

The Back Route of the castle goes beside the cut section and very narrow like the Main Route. It must have been made very defensive like the Main Route.

Later History

After Shibushi Castle was abandoned, the foot of the mountain was used as the warriors’ residences called Shibushi Fumoto. Fumoto refers to a residence area for a unique defense system of the Satsuma Domain led by the Shimazu Clan, called Tojo or the Outer Castles, during the Edo Period. Unlike other domains letting their retainers live together in their home base, the Satsuma Domain sent many of its retainers to their local sites to protect the frontiers of its territory. Shibushi Fumoto was one of the most important among over 100 Fumoto of the domain. You can also walk around the Fumoto area at the same time as visiting Shibushi Castle Ruins. As for the castle ruins, they have been excavated and researched since 2003. As a result, they were designated as a National Historic Site in 2005.

The area around still has an atmosphere of Shibushi Fumoto

My Impression

I have never seen such a large and precise miniature model of a mountain castle like the one of Shibushi Castle (Uchijo portion) in Shibushi City Center for Archaeological operations before. I have certainly seen large and precise miniature models of more modern castles like Himeji Castle because they often had or still have many buildings such as the Main Tower, turrets and gates, and great structures such as stone walls. They would be easy to be copied for a model and the model can be popular with people. On the other hand, making models of a mountain castle should be difficult and may be less popular, so it could be rare, especially realistic ones. However, the miniature model of Shubushi Castle is one of the rarely seen models, worth to see by itself, and helps visitors understand what the real castle was very well.

How to get There

If you want to visit the castle ruins by car, it is about a 15 minute drive away from Shibushi IC on the Miyakonojo-Shibushi Road. There is a parking lot for visitors near the ruins. In addition, Shibushi City Center for Archaeological operations is about 3km away from the ruins and it also has a parking lot.
If you want to use public transportation, it takes about 20 minutes on foot to get there form JR Shibushi Station.
For visitors from Tokyo or Osaka: It may be a good idea to rent a car at Kagoshima or Miyazaki Airports after using a plane.

That’s all. Thank you.

Castle Ruins on Hiking Course

Today, the ruins of Kanayama Castle have been well developed by Ota City. The mountain, where the ruins were located, are covered by several hiking courses including the routes to the ruins, where you can see many people enjoying and relaxing on them. For history fans visiting the ruins, it may be better to climb Nishiyama (the Western Mountain) course from such as Historic Site Kanayama Castle Guidance Facility.

Drivers can also go straight to the parking lot on the mountain through the Kanayama Drive Way, about 700m away from the top, around Nishijo or the Western Castle area. The Western Mountain hiking course also meets the area, so a tour to the ruins usually starts there.

Defense system to prevent enemies from attacking Castle easily

To go to the center of the ruins, you need to go on the original or recently developed route towards the east. You will find several ditches which were built for preventing enemies from attacking the castle easily.

In particular, the one in front of the Lookout Tower was built by digging bedrock deeply, which looks very impressive. In addition, double entrances behind the ditch are surrounded by restored stone walls, and you can enter them after going across the earthen bridge over the ditch.

The tower above the entrance was rebuilt as an observation platform, where you can see great views of the city area and mountains around. This area must have been a pivot point of the castle.

Restored Main Entrance with Stone Walls and Paving

Next comes the main portion of the castle, called Mijo, which is divided by the Large Ditch, the largest one in the castle, and a small reservoir being covered with stone mounds, called Tsuki-no-ike or the Moon Pond.

Over the pond, you will see the outstanding Main Entrance in a valley, which are surrounded by great several tiered stone walls on both sides. The entrance also has stone paving with drainage ditches, so it looks like a European castle. These stone walls were recently restored by the officials based on the achievements of the excavations and studies, partially using the original stones.

They were thought to be completed by the Hojo Clan, the final owner of the castle. This is because they were piled in a method called Agodome style (in which all the stones in the bottom row are layered heavily to prevent the walls from collapsing) which the clan used in Hachioji Castle, their other branch castle. However, the excavation team also found that the stone walls were improved many times, so other clans might have started to build them.
