Heiwazumi Issui's "Chikujaku" is a representative work that connects the aesthetic beauty of the design inherited by the National Treasure Great Armor housed at Kasuga Taisha to the present day. This great armor is known as one of the pinnacles of Japanese armor, imbued with the dignity of a craft offered before the gods. Successive generations of Issui were fascinated by its symbolism and aesthetic sense, frequently visiting Kasuga Taisha and continuing to study it to this day. Against the backdrop of such accumulated exploration, "Chikujaku," refined with Issui's unique sense of flowing form while drawing deeply from tradition, is positioned as one of Issui's representative works.
