CastleFlatland castle (hirajiro)Japan's 100 Fine Castles No. 5
What makes this castle distinctive
A castle of earth and timber with no keep or stone walls, whose late-16th-century main enclosure has been rebuilt, building by building, from the post holes found in excavation.
Why?
Built in 1334, Ne Castle was the center of the Hachinohe area for about 300 years. Excavation and restoration from 1978 took about 11 years, and the main enclosure was rebuilt as it looked in the late 16th century, when the castle was at its peak. It is described as the first attempt in Japan to recreate an entire enclosure of a medieval-to-early-modern castle.[1][6]
The center of the main enclosure (honmaru, paid area) of the Ne Castle Site Park.
What to look at
The re-created scene of the New Year ceremony held on the 11th day of the first month, set in the main hall.
Why it's interesting
The shuden was where the lord received guests and held ceremonies. It shows that the heart of this castle was a single-story hall, not a tall keep. Inside you can see a recreation of one of those ceremonies.[1][2]
Can you see it?
Visible from outsideThe main enclosure charges admission (250 yen for adults). Closed on some days, including most Mondays.
Around the main enclosure and between it and other baileys such as Nakadate (in the free part of the park).
What to look at
The depth of the dry moats, the earthen banks beside them, and how the baileys connect by bridges and fences.
Why it's interesting
Ne Castle was a flatland castle of eight baileys, including the main enclosure, Nakadate and Tozenji-date, separated by moats and earthen ramparts. Its medieval defenses, built without stone walls, survive in the shape of the ground.[5][6]

The workshop where weapons were repaired, plus stables and storehouses
Where
Inside the main enclosure, around the shuden.
What to look at
The tools laid out in the thatched workshop, and displays showing how weapons and armor were made and repaired.
Why it's interesting
A castle was a place of daily life and work as well as war. With the workshop, board storehouse, barn and stables all rebuilt, it is easy to picture the jobs done inside the walls.[1]

Tradition
Built by Nanbu Moroyuki for the Southern Court
In 1333, when Kitabatake Akiie went to govern Mutsu Province on Emperor Go-Daigo's orders, Nanbu Moroyuki went with him. Akiie made Moroyuki the official in charge of Nukanobu District, and in 1334 Moroyuki is said to have built Ne Castle as a base for the Southern Court. The branch of the Nanbu family based here became known as the Ne Castle Nanbu, or the Hachinohe clan.[4][5]
03
Historical record
Three centuries as the center of Hachinohe
Together with the Ne Castle Nanbu, the castle came through the wars between the Northern and Southern Courts and endured through the Muromachi, Warring States and Azuchi-Momoyama periods in northern Tohoku. It had eight baileys, including the main enclosure, Nakadate and Tozenji-date, and the site covers about 185,000 square meters.[4][6]
04
Historical record
Demolition orders and a move to Tono
In 1590 Nanbu Nobunao of the Sannohe Nanbu was confirmed by Toyotomi Hideyoshi as ruler of all the Nanbu lands, and the Ne Castle Nanbu became his vassals. When Hideyoshi ordered castles across the country torn down, the Nanbu demolished most of theirs except Sannohe Castle, and Ne Castle lost its function as a fortress. In 1627 Nanbu Toshinao moved the Ne Castle Nanbu to Tono in today's Iwate Prefecture, and Ne Castle's history came to an end.[4]
05
Historical record
A park born from excavation
The site became a National Historic Site in 1941. Excavation and restoration from 1978 took about 11 years, and the main area opened in October 1994 as the Ne Castle Site Park. In the main enclosure the shuden hall was rebuilt along with a workshop, board storehouse, barn and stables. Excavations also turned up parts of armor and swords, ceramics and other finds.[1][4][5]
A medieval castle that never had a keep; the center of the main enclosure was a single-story hall.
The site today
The main area is open as the Ne Castle Site Park, free to walk. Only the main enclosure charges admission; inside, buildings of the late 16th century have been rebuilt. The Hachinohe City Museum stands next door (closed for renovation until June 2027).

Who will enjoy it
For anyone who wants to see a medieval warrior's castle rather than one with a keep, those curious about daily life inside a castle, and families. The park is free, so it is easy to drop in for a walk.
What makes it interesting
In the main enclosure, the shuden and workshop show the ceremonies and work that went on inside. Then walk the dry moats and earthworks between the baileys to see, in the shape of the ground, how a castle without stone walls defended itself.
Before you go
The buildings are reconstructions based on excavation, not originals. The main enclosure is closed on most Mondays and some other days. The neighboring Hachinohe City Museum is closed until June 2027.
Ways to enjoy it
Ask for a free volunteer guide (about an hour) to hear about the layout and the excavations as you walk. The 100 Castles stamp is also outdoors at the museum entrance, available 24 hours.
