The Iwamura Historical Museum, located in Iwamura-cho, Ena City, Gifu Prefecture, is a historical museum that clearly introduces the history of Iwamura Castle, one of Japan's three great mountain castles, and its castle town. The museum displays maps and models of Iwamura Castle, artifacts unearthed during archaeological excavations, and materials related to successive castle lords. Visiting the museum before exploring the castle ruins will enhance your visit.
Iwamura Castle developed as the residence of the Toyama clan, which existed from the Kamakura period, and is known for being the castle's guardian during the Sengoku period by Otsuya-no-kata, the aunt of Oda Nobunaga. The museum features materials related to Otsuya-no-kata and Akiyama Torashige (Nobutomo), a renowned general of the Takeda clan, and allows visitors to learn about the fierce battle for Iwamura Castle between the Takeda and Oda clans. The exhibits provide a tangible sense of how eastern Mino Province during the Sengoku period was the front line where the forces of the Takeda, Oda, and Tokugawa clans clashed.
The museum also introduces Iwamura Castle's distinctive six-tiered stone walls and its unusually large number of wells—17 in total—for a mountain castle. Understanding the ingenuity of its construction, such as "why so many wells were dug near the mountaintop," allows for a deeper understanding of Iwamura Castle's structure and background, aspects that might be difficult to grasp from the ruins alone.
The Iwamura Historical Museum is also the official stamp location for Iwamura Castle, one of Japan's Top 100 Castles. For castle enthusiasts nationwide, it's a starting point for their castle visits; a popular route involves getting the stamp, viewing the exhibits, and then heading to the castle ruins.
Particularly interesting is the fact that while very few buildings remain at the current Iwamura Castle site, the museum displays models and drawings that recreate its appearance in its heyday. By comparing the stone walls and baileys viewed from the castle ruins with the exhibits in the museum, one can more vividly imagine the impregnable mountain castle once known as "Kirigajo" (Mist Castle).
The Iwamura Historical Museum is more than just an exhibition facility; it serves as a guide to understanding the history of Iwamura Castle and its surrounding town. For those who want to gain a deeper understanding of Iwamura Castle, a place steeped in the romance of the Sengoku period, it is definitely one of the first places you should visit.
I was able to use the JAF card discount.
I don't think there are any particular problems, but photography is prohibited throughout the entire building.
In this day and age, I think having some areas where photography is allowed would help attract more visitors.
There's a bus stop right in front of the museum, but it's on a rare reservation system.
The restrooms are located behind the museum and are accessible to everyone.
The parking lot is also spacious.
We arrived after a 30-minute stroll through the castle town from Iwamura Station on the Akechi Railway. Even getting here involves quite a bit of climbing. We happened to arrive on the day of Rally Japan, so it was incredibly crowded.
You can get the 100 Famous Castles stamp for free upon entering the entrance.
Seeing the kind old man at the reception, I ended up paying the entrance fee.
