Armor (Gusoku) 19th century Japanese Although constructed in the traditional sixteenth-century gusoku (complete set) fashion, this is actually an example of the revival of earlier armor styles during the Edo period. It was part of the large collection of Japanese arms and armor formed by Arms and Armor Department founding curator Bashford Dean around 1900, during his extended stays in Japan for scientific research. The armor was included in the Metropolitan Museum's 1903 loan exhibition of Japanese arms and armor from Dean's private collection, which the Museum purchased in 1904.. Armor (Gusoku) 22020
