The site of in Hakodate, Hokkaidō, Japan, is that once occupied by the Shinori Fort or Fortified Residence (as denoted by the tate or date ending). This was the easternmost of the so-called "Twelve Garrisons of Southern Hokkaido", built on the Oshima Peninsula by the Wajin from the fourteenth century.[1] [2] The site was designated a National Historic Site in 1934 and is one of the Japan Castle Foundation's Continued Top 100 Japanese Castles.[3] [4]
Shinoridate is located some 9km (06miles) to the east of the center of Hakodate, along a stretch of coast with many good natural harbours. A short distance inland from Shinori Fishing Port, with the mouth of the Shinori River to the west, the gently sloping site overlooks the Tsugaru Strait and Shimokita Peninsula, with views also towards Mount Hakodate.[1] [5]
The earthworks rise to a height of 4mto4.5mm (13feetto14.8feetm) on the north side and 1mto1.5mm (03feetto04.9feetm) to the south and are interrupted by an opening on both the east and the west sides. The moat is 5mto10mm (16feetto30feetm) wide on the north and west sides and up to 3.5m (11.5feet) deep and is crossed by two earth bridges, that to the west particularly well-preserved.[1] [5]
First laid out around the end of the fourteenth century, Shinoridate features in the Matsumae Domainal history Shinra no Kiroku, which tells of it being sacked by the Ainu in Chōroku 1 (1457), during Koshamain's War, and again falling to the Ainu in Eishō 9 (1512), after which its occupants, the, became subject to the Matsumae clan.[1] [6]
The Hakodate City Board of Education conducted excavations and surveys of the enclosure and surrounding area between 1983 and 1985, uncovering the remains of a number of buildings, palisades, a well, artefacts made of bronze, iron, stone, and wood, celadons and white porcelain from southern China, as well as domestic Suzu, Echizen, and Seto ware.[1] [5] [7]
Three different intercolumnar measurements were used in the construction of the buildings, the style of the well is that found in Heian-kyō in the late Kamakura period, while many of the ceramics are typical of the early fifteenth century.[5]
Accordingly, three main phases have been identified: the end of the fourteenth or early-fifteenth century; mid-fifteenth century; and sixteenth century or later. With the archaeological evidence pushing back the origins of the fort at least half a century before Koshamain, its construction can no longer be understood as an immediate response to the contingencies of 1457, and other explanations are required.[5]
In July 1968, during widening work on the prefectural road (now National Route 278) that runs past the fort, a Nanbokuchō-period (C14) coin hoard was unearthed some 40m (130feet) inland from the mouth of the Shinori River, at a location 3m (10feet) above sea level. This is the largest hoard found to date in Japan in terms of the number of coins it contains.[5]
The three large vessels excavated weighed, together with their contents, 1.6tonne. Ninety-three different types of coin have been identified: a handful in total of early Japanese coinage of the Asuka, Nara and early Heian periods, late tenth-century Vietnamese coinage of the Đinh and Early Lê dynasties, and late eleventh-century Goryeo coinage from Korea; the bulk comprising Chinese coinage, primarily of the Song dynasty, issues ranging in date from 4 Zhu Ban Liang minted in the fifth year of Emperor Wen of Han (175 BC) to Hongwu Tongbao from the first year of the Hongwu Emperor, founder of the Ming dynasty (1368).[5] The 374,435 coins from this hoard now at the Hakodate City Museum have been designated an Important Cultural Property.[8]
A 1999 study of 275 Japanese hoards, totalling 3,530,000 coins, found that the Chinese copper coins used in Japan in the Middle Ages were brought over in the largest number in the thirteenth century, were used primarily in commerce or for paying soldiers, and were buried largely for reasons of security, although there were also instances of ritual or votive deposits.[9] [10] The dating of the Shinori hoard precludes its burial as a response to Koshamain's War; instead it may relate to trade, the local Shinori or Kaga kombu featuring alongside Ezo salmon in the Nanboku-chō period text . Produce from the area would have been traded along the Hokuriku coast to reach the markets of Kyōto and Ōsaka.[5]
