History and Lords of Shinohara Castle
Shinohara Castle as Seen in Documents
Regarding the detailed construction period and lords of Shinohara Castle, reliable historical sources are scarce, and different descriptions can be found in multiple documents. According to “Medieval Castles and Residences of Tokushima Prefecture,” there are two theories regarding the lord of this castle.
“Awa-shi” identifies Tachibana Tadamasa as the lord. The Tachibana clan was a prominent family from ancient times, and there were samurai groups of the Tachibana clan within Awa Province. On the other hand, the “Awa County History” lists Shinohara (someone) as the castle lord, suggesting the possibility that the Shinohara clan was the lord, given the connection to the place name.
The Position of Shinohara Castle in Awa Province
Medieval Awa Province was a region where powerful warlords, including the Miyoshi clan, held sway. The area north of the Yoshino River, where Shinohara Castle is located, was a crucial transportation hub connecting the central part of Awa Province with Sanuki Province, and is thought to have been a strategically important base despite its small size.
The place name Shinohara is highly likely to originate from the Shinohara clan, who were the developers of this region, and it is presumed that it functioned as the residence of a local lord who ruled this area from the late Heian period to the Kamakura period.
Changes After the Sengoku Period
During the Sengoku period, Awa Province came under the control of the Miyoshi clan and was further invaded by the Chosokabe clan. Following Toyotomi Hideyoshi’s conquest of Shikoku, the Hachisuka clan became the rulers of Awa Province. While the exact date of Shinohara Castle’s abandonment is unclear, it is believed that by the early Edo period, it had already lost its function as a castle and become part of a settlement.
Structure and Layout of Shinohara Castle
Scale and Form of the Castle
Shinohara Castle is a typical medieval flatland castle (residence), lacking the complex layout of large mountain castles or early modern castles. The current grounds of the An’nai Shrine are thought to roughly correspond to the castle’s area, indicating a relatively small scale.
According to the “Comprehensive Survey of Japanese Castles,” a dry moat and earthen ramparts once existed, but the ramparts are no longer visible. It is believed that many remains have been lost due to years of development and the construction of the shrine.
Traces of a Water Moat
Currently, the most clearly remaining trace of Shinohara Castle is the pond located on the south side of the An’nai Shrine grounds. This pond is thought to be a remnant of the castle’s moat, and is featured as a moat site on castle information websites such as “Castle Wanderings” and “Castle Siege Group.”
In medieval residences, it was common to surround them with moats as a defensive feature. Based on the current shape and location of the pond, it is highly probable that Shinohara Castle was a square-shaped residence surrounded by a moat, primarily on the south side.
Relationship with An’nai Shrine
Currently, An’nai Shrine stands on the site of Shinohara Castle. It is common throughout Japan for shrines to be built on the site of abandoned castles. While the exact date of An’nai Shrine’s founding is unknown, it can be said that it has continued to protect the castle site as the guardian shrine of the region.
The shrine grounds are well-maintained, and although there are few clear traces of the castle’s remains, the micro-topography and surrounding land use allow one to imagine the former castle area.
Highlights of Shinohara Castle
Strolling through the An’nai Shrine Grounds
An’nai Shrine is the central point of interest when visiting Shinohara Castle. The shrine itself is small but deeply rooted in the community, and its grounds are enveloped in a quiet and peaceful atmosphere.
When walking around the grounds, if you pay attention to the changes in the terrain and the differences in elevation with the surrounding area, imagining that this was once the residence of a samurai, you can sense the remnants of a castle.
Observation of the Moat Remains (Pond)
The pond located south of the shrine is the most important remains of Shinohara Castle. While it may currently be used as an agricultural reservoir, its location and shape indicate that it is a remnant of the castle’s moat.
Observing the area around the pond provides clues to inferring the scale of the moat and the extent of the castle grounds. Paying particular attention to the positional relationship between the pond and the shrine grounds reveals the layout of the residence.
Location of the Shinohara Castle Monument
A monument marking the castle site stands at Shinohara Castle, but its location requires careful observation. According to information from the Kojodan (Castle Attack Group), the monument is located northwest of the shrine, beyond the fence where solar panels are installed.
Since it’s often difficult to find within the shrine grounds, visitors are advised to confirm the exact location of the stone monument beforehand. You should be able to find it by searching along the perimeter fence of the solar panel facility.
Castle Notes: Points to Note When Visiting
Here’s a summary of points to note when visiting Shinohara Castle:
- State of Remains: Since no clear earthworks or stone walls remain, those expecting extensive castle ruins may be disappointed.
- Location of the Stone Monument: Note that it’s not within the shrine grounds, but near the solar panel facility to the northwest.
- Moat Remains: The pond on the south side is the clearest remains, so be sure to check it.
- Time Required: Approximately 15-30 minutes for observing the shrine grounds and surrounding area.
- Photography: Photography is permitted within the shrine grounds, but please refrain from entering private property or the solar panel facility.
