The Shitohe clan, a branch of the Nanbu clan

.ShinoheIt is said that the Nanbu clan originated when Munekiyo, the fifth son of Nanbu Mitsuyuki, the founder of the Nanbu clan who moved from Kai to Oshu, was granted the territory of Shinohe and adopted the surname

The branch families of the Shinohe clan include the Takeda clan, Kindaichi clan, Kushibiki clan, Nakano clan, and Nukazuka clan, and the castles that these branch families used as their residences came to be called Shinohe Castles in various places

It is thought that this is why there were "four households" scattered throughout Nukabe County


Where is the location of "Yonhe" as suggested by local documents?

The area believed to be "Shinohe" is around the map shown above. Based on a comprehensive analysis of local historical materials remaining in various regions, it.is highly probable that the Asamizu, Kenkichi, Nakui, Fukuda, Tomabechi, Kushibiki, and Shimamori districts in the lower reaches of the Mabuchi River are the area that constitutes Shinohe

compiled by Iwate PrefectureIwate Prefectural History, states that the Shinohe district, which was granted to Munekiyo, was located in Ninohe County, and Kindaichi is considered to be that location. As such, the candidate locations are scattered widely within the territory of the Nanbu clan, as listed below.

The theory that it is the Asamizu River basin that flows through Gonohe Town

Asamizu Hachiman Shrine
Asamizu Hachiman Shrine (the remains of Asamizu Castle) is located on a hill overlooking the road and the Asamizu village

TheAsamizu River is a tributary of the Mabuchi River and flows from west to east between Sannohe Town and Gonohe Town.

Asamizu in particular is said to have been a small post town along the highway, and there are records that state that Nanbu Munekiyo, the ancestor of the Shinohe clan, was the first to live in this area, making it a likely candidate for Shinohe

Additionally, Asamizu is a strategic transportation hub bordering Sannohe to the south, Hachinohe to the east, and Gonohe to the north, and the theory that it was likely used as a defensive base for Sannohe is also one of the reasons for the theory that Asamizu is Yonnohe

Nozawa Castle Ruins

In the Asamizu River basin,Asamizu,Shidogishi, andNusa, and these have been suggested as candidates for the location of Shinohe. There is a theory that the castle ruins remaining in Asamizu and Nusa might be the site of Shinohe Castle.

Theory that it is near Kushibiki in Hachinohe City

Kushihiki Hachimangu ShrineisShinohe Hachimangu Shrine, one theory suggests that Shinohe was the area from around the shrine to the present-day Nanbu Town, and that the Kushihiki clan, the lords of Kushihiki Castle, ruled that area.

who owned a vast territory stretching from Hachinohe City to Gonohe Town and Ninohe City in Iwate PrefectureKushibiki, was defeated when he rebelled against Toyotomi Hideyoshi in the Kunohe Rebellion, losing his territory and causing the Shinohe clan to disappear.

This theory has been advocated by Mr. Takijiri, a curator at the Hachinohe City Library in Iwate Prefecture, and was broadcast by NHK Aomori Broadcasting Station on October 20, 2023, and was also featured in a special web feature on the station

This theory identifies the Kushibiki family"the lords of Shinohe,"meaning they were the head family of Shinohe, and uses this as evidence that Kushibiki is indeed from Shinohe. In fact,Records of the Southern Regionsuch a description can be found in the Ounan Kyushiroku (Okinawan

However, other historical documents suggest that the Kushibiki clan was likely a branch of the Shinohe clan, and some even state that they served the Sannohe Nanbu clan and held a fief of around 2,000 koku

This theory also states that Kushibiki Kiyonaga's territory of Shinohe was "divided between Hachinohe and Sannohe after the rebellion, causing Shinohe to disappear," but the Negishi Nanbu clan, who ruled Hachinohe at the time, were vassals of the Sannohe Nanbu clan

Therefore, it is considered legitimate to assume that all of the Kushibiki clan's territories were given to the Sannohe Nanbu clan, and for these reasons, there seem to be many voices that question this theory

One theory is that it was located in Kindaichi in the northern part of Ninohe City

Yasaka Shrine is located just before the ruins of Kindaichi Castle. Behind this shrine is the castle ruins

There are documents that state that the Shinohe clan moved from Asamizu Castle to Kindaichi Castle in Ninohe County in the middle of the Sengoku period, and this theory arose from the fact that Kindaichi Castle was called Shinohe Castle

Kindaichi Castle is located on a river terrace on the left bank of the Mabechi River, and it is said that the upper, middle, and lower buildings, separated by dry moats, were the residences of the Shitohe, Kirimaru, and Kindaichi clans, respectively, making it a castle with a complex history

Yasaka Shrine
The approach to Yasaka Shrine is just wide enough for one light car to pass through, just like Asamizu Hachiman Shrine

It is believed that this castle came to be called Yonohe Castle because the Yonohe clan, who had previously ruled Yonohe and used the place name as their surname, moved there, and there seems to be little support for the theory that Yonohe was located in Ninohe County

As we have seen so far, there are many different theories about where Yonhe was located and why its name disappeared, and there is still no consensus

However, it is believed that it must have existed somewhere in Nukabe County, and searches for its location are still ongoing

Let's hope that some new discoveries will be made in the near future, leading to the identification of the four houses and the solution to the mystery
