Iwamura Castle (岩村城, Iwamura-jō) was located in the southeastern area of Mino Province in Japan. Its ruins can be found in the modern-day municipal subdivision of Iwamura, in Ena, Gifu Prefecture.[1] Along with Takatori Castle in Nara and Bitchu-Matsuyama Castle in Okayama, it is regarded as one of the three best mountain castles, and at an elevation of 721 meters above sea level (200 meters above its immediate surroundings), it is one of the highest in Japan.

History

Iwamura Castle is situated on a steep mountain overlooking the Iwamura Basin. The area commands an intersection of the Sanshu Kaidō, which connected southern Shinano Province with central Mikawa Province and the Pacific Coast, and the road connecting Mikawa Province with Tōtōmi Province to the east. In the Sengoku period, this area was of great strategic interest to both Takeda Shingen and Oda Nobunaga.

During the Kamakura period, eastern Mino was held by Kato Kagekado a vassal of Minamoto no Yoritomo.[2] His descendants formed cadet branches named after their residence, and through the Muromachi period, Iwamura was ruled by the Tōyama clan. The Tōyama were never a very strong clan, and were forced to pledge fealty to whichever of their neighbors was more powerful at the time. In 1545, they were subordinate to the Takeda clan. However, Oda Nobunaga was eager to build a relationship with the Tōyama, primarily as they bordered the lands of his arch-nemesis, Saitō Dōsan of Gifu. To this end, Nobunaga sent his aunt, Otsuya-no-kata, to marry Tōyama Kagetō. As the couple did not produce an heir, Nobunaga further sent his sixth son, Oda Katsunaga to be adopted into the clan.

In 1565, Nobunaga began his campaign against eastern Mino in earnest. At first, he maintained an agreement with

Siege of Iwamura, the Tōyama initially drove the attackers off, but with great losses, including that of Tōyama Kagetō, who died of injuries sustained in the attack. His widow, Otsuya-no-kata, assumed command and held out for several more months, before reaching a surrender agreement. Per this treaty, her adopted son (Oda Katsunaga) was sent to Kai Province as a hostage, and she was compelled to marry Akiyama Nobutomo. The remaining Tōyama forces joined the Takeda, a move which enraged Oda Nobunaga, who attacked Iwamura Castle on repeated occasions. In 1575, following the decisive defeat of Takeda Katsuyori at the Battle of Nagashino, Oda forces surrounded Iwamura Castle, but it continued to hold out. After six months of siege and battle, Otsuya-no-kata responded to a call for negotiations. However Nobunaga reneged on his word and had Otsuya-no-kata and Akiyama Nobutomo crucified as traitors on December 23, 1575.[3][4]
The remaining defenders within the castle were all slaughtered and theIwamura branch of the Tōyama clan was extinguished.

In 1582 Oda Nobunaga began his conquest of Kai Province, staying at Iwamura Castle to receive reports of the results of the war. Afterwards, the castle was given to

Subsequent to Meiji revolution, all of the remaining buildings of the castle were demolished in 1873, with the exception of one gate which was moved to a neighboring temple. All that remains at present are some remnants of stone walls on the mountain.
