Shinoridate, Medieval castle ruins in eastern Hakodate, Japan
The fortress occupies 4,100 square meters on a coastal terrace, featuring earthen walls on four sides and two entrances on the east and west.
The castle fell during the Koshamain War in 1456, and again in 1512 when the Ainu attacked, leading to the death of Lord Kobayashi Yataro Yoshisada.
Archaeological excavations between 1983 and 1985 revealed celadon, white porcelain, and Suzu pottery, confirming the dating of the Koshamain War in 1457.
Visitors can reach the site by taking the Hakodate Bus line 91A from Hakodate Station to Shinoribashi stop, followed by a three-minute walk.
The site yielded 380,000 ancient Chinese coins in 1968, representing the largest discovery of medieval currency in Japan.
