Miyao Castle

History

The castle was built by Mori Motonari in 1555 on the island of Miyajima. It was a very small castle in a visible location intended to lure Sue Harutaka into a trap. Sue took the bait in September 1555 and took an overwhelming force to the island. He built the To-no-oka fort in the shadow of the Itsukushima Shrine on Sept 16 and easily attacked and took Miyao Castle on September 21. While Sue was preoccupied with Miyao Castle, Mori took Sakurao Castle, one of Sue's most critical castles on the mainland. In a thunderstorm on October 1, the Mori positioned their forces for a damn attack on the castle. The Sue forces were defeated, those the fled the island by ship were hunted down by the Murakami, allies of the Mori. Sue Harutaka himself, seeing the hopelessness of his situation committed seppuku.

As a sacred site, no castle had been built on Miyajima Island where blood could not be shed in birth nor fighting. After the battle, Mori removed all the bodies of the fallen, scrubbed down bedrock and buildings where blood had been shed and even removed blood soaked soil. In the following years Mori Motonari also funded several construction projects for the Itsukushima Shrine. No further castles were built on the island after Miyao Castle was abandoned.

Visit Notes

If you're going to Miyajima anyway this really is a must see stop for castle fans. There are very few remains to be seen of this fortification, but the horikiri trench is impressive. It is also an historically important site for the decisive victory of the Mori over the Sue in a battle of wits.

Apparently there is also one called 安藝勝山城跡 on the otherside of the shrine.

It was Sue's first base/encampment before moving to To-no-oka. In some blog I read, the writer asked at the temple about it but the temple person he had not heard the story and did not believe it :)
