A case carried on the back by monks of Kannon-ji, a temple strongly associated with the Sanriku region and Hiraizumi's
Chuson-ji Temple. Buddhist images, Buddhist ritual implements, and sutra scrolls would be stored in the case, which was worn like a rucksack. It is a superb piece of craftsmanship, covered in gold, with Buddhist motifs worked onto every surface. It is a beautiful piece that passes down historical goldworking techniques to the present day.
