A Castle Site, Designated in 2008
Sashiki Castle Ruins (佐敷城跡, Sashiki Jo Ato) is a castle site at Ashikita Town, Ashikita District, Kumamoto Prefecture, designated on 28 March 2008. Its category is historic site, place of scenic beauty and natural monument.
It stands apart from the categories covered so far. Historic sites are designated, where the cultural landscape of the previous entry was selected: a different verb.
The era field carries four entries at once: Momoyama, Muromachi, Kamakura and Nanbokucho. One site spans several periods.
The Same Name in Kumamoto and in Okinawa
This is not the only historic site called Sashiki Castle Ruins.
Nanjo City in Okinawa Prefecture has one as well, designated on 17 October 2013, under the same category.
Their histories have nothing in common. The Kumamoto site is held to have been built by Kato Kiyomasa; the Okinawa site is held to have been the seat of Sho Hashi, who unified Ryukyu.
With the Twelve Devas, two properties shared name, count and owner, and only period and museum could separate them. With the tachi inscribed Masatsune, several swords carried the same signature.
This case differs again. Two places happen to bear the same name, and nothing else connects them. The prefecture must be added or they cannot be told apart.
Demolished Twice Over
The strangest thing in this record is how the castle was pulled down.
The Agency notes that it was abandoned as a castle under the one-castle-per-province edict of 1615. That was the first demolition.
But there is more. In 1638 the Hosokawa removed the stone walls afresh, on the grounds that the demolition carried out by the previous lords, the Kato, had been insufficient.
Twenty-three years later the work was done again because it had not been done thoroughly enough. One lord's demolition was judged inadequate and the next lord took it up.
At Aoi Aso Shrine, the record showed building spread over several years. A record of demolition in two stages is new here.
The State of the Demolition Counts as Value
The assessment makes the same point.
Large quantities of roof tiles were excavated, among them ridge-end tiles bearing an inscription praying for peace under heaven and quiet in the land, ridge-end tiles with a paulownia crest, and eaves tiles dated 1607 associated with the third phase of the stone walls; and the state of the demolition was also well confirmed.
The demolition is listed alongside the excavated tiles. What was destroyed forms part of the site's value.
The Gobu Shinkan scroll writes a loss into its title, and the Hirabaru mirrors, found broken, forced a special manner of counting. Those record that something was lost or damaged.
Here it is otherwise. The act of demolition itself is treated as information the site yields. The Agency closes: an important site for understanding politics and military affairs at the beginning of the early modern age.
Visiting
The site lies at Ashikita Town, Ashikita District, Kumamoto Prefecture. Being a castle site, it has neither an owner nor a managing body entered in the record.
Its layout is recorded: around the main enclosure, second and third enclosures descend in steps to the south, with an outer enclosure set along the ridge.
The approach is described as well: the east side of the castle hill, where the town and the Satsuma highway ran, served as the main entrance, with three gates in succession, each with a square barbican.
Of the walls: the main, second and third enclosures are entirely walled in stone, and the eastern approach in particular carries high stone walling. Even after two removals, walls worth recording remain.
As an outdoor site, conditions for visiting differ from those for a building. Check the town's information before travelling.
