Obata Castle (小幡城) is a former flat mountain castle (平山城 hirayama) in Moriyama Ward, Nagoya.

Obata Castle (小幡城)

The castle is said to have been built in 1522 by Okada Shigeatsu (岡田重篤), a vassal of Oda Toshinobu. The castle was then occupied by Matsudaira Kiyoyasu (松平清康, 1511-1535), Tokugawa Ieyasu's grandfather, before he marched on Moriyama Castle. The castle was abandoned after it became the residence of Oda Nobumitsu (織田信光, 1516-1556). Tokugawa Ieyasu then restored it during the Battle of Komaki Nagakute in 1584. Ieyasu, who had detected the movement of Ikeda Tsuneoki and others who wanted to surprise attack Okazaki Castle, tracked Ikeda's army and stayed at Obata Castle. The two armies clashed at Nagakute, southeast of the castle, where the Tokugawa forces defeated Ikeda Tsuneoki and his son Motosuke and Mori Nagayoshi to win the battle.

On that particular day, we visited Moriyama Castle, Obata Castle and Ryusenji Castle in Moriyama Ward. The topographical map shows that the castles were built on the northern edge of the plateau between the Shonai and Yada rivers. Incidentally, the Japan Ground Self-Defence Force Garrison is still located between Moriyama Castle and Obata Castle.

An enlarged view of the area around Obata Castle shows that it was situated at the tip of an elevated plateau jutting out towards the northwest. However, no remains remain today, only an information board.

Walking from the north, you reach an uphill slope. The castle was built on top of it. It is slightly elevated and seems just right for setting up camp in the middle of a march.

The following photos were also taken from the bottom of the hill. The building at the top of the mountain is the Moriyama Care Community Soyokaze, a magnificent structure that looks like a castle building.

Up the hill, directly opposite Breeze, is the castle's information board.

Near the guideboard is a temple called Amidaji, also known as Jōshisan Amidaji (城址山阿弥陀寺). There is no parking space for visitors to the castle ruins, but it may be possible to borrow a parking space while paying a visit to the temple.
