What makes this castle distinctive
Tradition places the home of the Kamakura-era warrior Hatakeyama Shigetada here, but the 5-meter ramparts and deep moats you walk among today belong to a Warring States castle built some 300 years later.
Why?
The Azuma Kagami, the Kamakura shogunate's official chronicle, records that in 1205 Shigetada set out from "Sugaya residence" on his final march, and that is taken to be this site. But the museum explains that all the surviving earthworks date from the Warring States period, and nothing from Shigetada's time has been found so far.[3][1]
The height of the ramparts and the steep 45–50 degree slope from rampart top to moat floor.
Why it's interesting
Ramparts facing the hand-dug moats stand about 5 m high and about 15 m wide at the base. Excavation showed the moats were about 12 m wide at the top and 5 m deep, and the slope from rampart to moat floor is 45–50 degrees, making the castle very hard to attack. Because the water table is high, some moats hold water or mud.[2]
Ramparts bent at right angles or zigzagged like a folding screen (ori), and ramparts projecting outward (demasugata).
Why it's interesting
By bending ramparts and pushing them outward, defenders could strike attackers from the side. Such features are thought to have appeared in the Warring States period, showing that this was rebuilt as a Warring States castle rather than left as a Kamakura-era residence.[2]

The rebuilt bridge at the Shoten Gate and its screening rampart
Where
The Shoten Gate site, where the West Enclosure leads into the Third Enclosure.
What to look at
The sloping wooden bridge and the shitomi rampart inside the gate that blocks the view in.
Why it's interesting
The ground at the Third Enclosure's entrance was raised about 1 m above the West Enclosure so the wooden bridge slopes upward, and a screening rampart inside the gate kept outsiders from seeing in. Today's bridge is a reconstruction.[2]

Sugaya Yakata sits on a terrace near the middle of the Hiki Hills, overlooking the Toki River. To the south the river has cut a cliff, and to the east and west several valleys slice into the terrace; the enclosures were laid out to make the most of this landscape. Close by ran the old Kamakura Kaido road linking Kozuke Province (Gunma) with Musashi.[4]

Tradition
Traditionally Hatakeyama Shigetada's home
Hatakeyama Shigetada, a Kamakura-era warrior of Musashi, served Minamoto no Yoritomo and won fame in many battles. He is said to have moved from his family's estate at Hatakeyama (today's Fukaya) to Sugaya, a key point on the Kamakura Kaido, and built a residence here. Local tradition puts his house in the central enclosure, but without excavation there it cannot be confirmed.[3][5][2]
03
Historical record
1205: setting out to his last battle
According to the Azuma Kagami, on the 19th day of the 6th month of 1205, hearing of trouble in Kamakura, Shigetada left "Sugaya residence" with only 134 horsemen. On the 22nd he was ambushed by a large Hojo force at Futamatagawa (in today's Asahi Ward, Yokohama) and was killed along with his son and retainers.[3]
04
Scholarly interpretation
Rebuilt as a Warring States castle
After Shigetada, only scattered records mention the site, but it is thought to have been rebuilt several times in the Warring States period and expanded into a castle. The Yamanouchi and Ogigayatsu branches of the Uesugi clan fought nearby at Sugayagahara in 1488, and the Yamanouchi Uesugi are thought to have restored the castle after that. The castle of about 130,000 square meters you see today reflects this Warring States phase.[1][4][6]
05
Historical record
The buildings vanished; the earthworks stayed
The buildings and wells that once stood in the enclosures are all buried, and the site is now lawns and woods. Excavations found building and well remains thought to date from the Edo period, and posts in front of the museum mark where one building stood. The ramparts and moats, protected by local people, have survived almost undamaged.[2][3]
06
Historical record
From prefectural to national site, with a museum
The site became a prefectural historic site in 1923, and in 1929, with local support, a statue of Shigetada was erected on a rampart of the second enclosure. It was designated a national historic site in 1973, and in 2008 it was renamed "Hiki Castle Sites: Sugaya Yakata" together with the Matsuyama, Sugiyama and Ogura castle sites. Inside the site stands the Saitama Prefectural Ranzan Historical Museum, devoted to the medieval period.[3][1][5]

A medieval residence-fort and castle; it never had a keep.
The site today
The roughly 130,000-square-meter site survives as lawns and woods open to walk, with the Saitama Prefectural Ranzan Historical Museum inside. It is a site traditionally linked to a Kamakura-era warrior's residence (yakata) that was rebuilt as a castle in the Warring States period, so it differs in origin from Edo-period castles.

Who will enjoy it
Good for fans of Kamakura-era samurai and Hatakeyama Shigetada, and for anyone who wants to walk a medieval earthwork castle without stone walls. Walkable from the station and with a museum for background, it makes a good introduction to medieval castles.
What makes it interesting
It is fascinating to keep in mind the 300-year gap between the legend of Shigetada's home and the Warring States ramparts and moats in front of you. Look for the flanking devices: the bends and bastions of the Third Enclosure, and the bridge and screening rampart at the Shoten Gate.
Before you go
The museum is generally closed on Mondays and occasionally for exhibition changes. There is no bus from the station. Download the museum's illustrated walking guide (PDF) to learn the enclosure names and route before you go.
Ways to enjoy it
See the museum's displays on the medieval Hiki area and the site first, then walk a loop from the rear gate to the main gate site in the West Enclosure. On a rampart of the second enclosure stands the 1929 statue of Shigetada.

Open questions
Identifying this as Shigetada's residence rests on the Azuma Kagami's mention of "Sugaya residence" and local tradition; no remains from his time have been found.
Who rebuilt the castle in the Warring States period is unclear; it is thought to have been restored by the Yamanouchi Uesugi. The Japan Castle Foundation's list names Uesugi Akisada among its lords.
Enclosure names such as honkuruwa and ninokuruwa were given after the Meiji era; the medieval names are unknown. Parking fees, opening hours, accessibility and photo rules are unconfirmed.
