\u003Cbr/>【開国・開港】","The Wadamisaki/Minatogawa Battery (Daiba) was a Western-style battery built in 1863, along with the Nishinomiya and Imazu batteries, in Wadamisaki and Minatogawa as part of the defensive measures for Osaka Bay at the end of the Edo period. The construction of the gun emplacements was headed by Nagayuki Ogasawara, a senior vice-minister appointed to the post of \"Odaiba Chutsukuri Goyokake,\" and was carried out by the magistrate for accounts, the magistrate for Osaka Town, the chief steward and his subordinates, with Jiro Kano, a branch of the Nada sake brewer Hon Kano in charge of the shipping department, serving as the subcontractor. From these documents, we can learn not only the structure, materials, standards, and cost of the turret, but also the decision-making process of the Imperial Household regarding the procurement of materials and design changes. Of the four platforms built by the Shogunate at this time, those at Wadamisaki and Nishinomiya are still in existence and are designated as national historic sites. \u003Cbr/>\u003Cbr/>[Opening of Japan and Ports",{"name":41,"catalogueNumber":9,"cataloguePage":9},{"ja":42,"en":43,"en_machine":9},"文化庁「文化遺産データベース」より取得した収蔵品データ. 取得日2022-01-21.","Data extracted from Bunka Isan Dētabēsu (Cultural Heritage Database) by Agency for Cultural Affairs (Bunkachō).
