Tsutsumi / tsuzumi dou, the Japanese equivalent of the famed coat-of-plates. This is a kawazutsumi dou, as it is wrapped in leather, although samples enclosed by fabric, notably layers of heavy silk ( nuno-tsutsumi) are also extant. They were of originally of kozane construction they could just as easily be made of solid lames. The lames (scale or solid construction) are overlaid with leather or fabric, and rows of cross-lacing serve to secure the leather to the plates. Muromachi era form.
