This item has been stored at my parents' house for many years. It's a decoration for the Tango no Sekku (Boys' Day) festival? It's an iron kabuto (helmet) (the material is probably iron). The helmet itself doesn't seem to have any noticeable scratches or stains, but the decorative tassel cords have some dirt and damage. The box is quite damaged and dirty. The family was blessed with sons, and a bountiful harvest?
