According to the Agency, it is one of the new, highly individual tosei gusoku armours fashionable in the Warring States period.

Construction

According to the Agency, the body is a two-piece hinged iron cuirass of black-lacquered iron plates laced sparsely with black thread. The helmet is a twelve-plate ridged iron bowl in black lacquer, with a lion-face front crest bearing twin horns in black-lacquered wood and a pair of large antler-shaped side crests.

The sleeves, thigh and shin guards are joined with iron chain mail; the face guard is embossed iron with a black-laced throat guard; the rosary has gilded abacus-bead shapes of wood. The body is 39.0 centimetres high and the helmet bowl 17.8 centimetres.

What to Look For

The Agency calls it rich in character, with its two-piece body, black-lacquered plates, large antler crests and great rosary worn over the shoulder.

It is also historically significant as the armour of Honda Tadakatsu, active at the start of the early modern period.
